Abstract The EFSA Plant Health Panel performed a pest categorisation of Setoptus parviflorae (Acari: Eriophyoidea: Phytoptidae) for the European Union (EU). This mite is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is known to occur in the Nanjing Botanical Garden (China) on Pinus parviflora. This is its only known host plant and location. The mite occurs on the needles and in the needle sheaths. Details about its life cycle are mostly unknown. Plants for planting, including dwarfed plants, of P. parviflora are the main potential pathway for entry into the EU. However, plants of the genus Pinus other than fruit and seeds are mostly prohibited from entering the EU (Commission Implementing Regulation (EU) 2019/2072). The host, P. parviflora, can be found in temperate‐zone gardens and arboreta, and is a popular tree for bonsai in the EU. Although the Köppen–Geiger climate type Cfa (humid subtropical), which occurs in Nanjing, can be found in the EU, the growing conditions of P. parviflora at the Nanjing Botanical Garden were not reported. This adds uncertainty about where in the EU this mite could establish, most probably on ornamental P. parviflora. There is no evidence of impact of S. parviflorae. Measures to prevent entry and spread are available. S. parviflorae does not satisfy all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest, as there is no evidence of impact.

The EFSA Panel on Plant Health performed a pest categorisation of Blissus insularis (Hemiptera: Heteroptera: Blissidae) for the European Union (EU) territory. B. insularis, known in the US as the southern chinch bug, primarily feeds on St. Augustine grass (Stenotaphrum secundatum, Poaceae, subfamily Panicoideae). This is a lawn grass grown in warm, tropical and subtropical regions of the world and which is widely grown in the southern US and also used in southern EU as a lawn and amenity grass. Adults and nymphs aggregate to feed at the base of the grass. B. insularis occurs in the southern continental US, Hawaii, Guam, Mexico, Central and South America, and across the Caribbean. In the EU, B. insularis was first detected in Portugal in 2019, where following a national survey, it has now been found in 10 municipalities across the central and southern parts of the country. The pathway for entry into Portugal is unknown. B. insularis is not a regulated pest in the EU. It could further enter and spread within the EU via the import and movement of host plants for planting. S. secundatum is vegetatively propagated because seed is largely sterile. Many Poaceae plants for planting are prohibited from entering the EU, other than some ornamental perennial grasses. Whether S. secundatum is considered an ornamental grass within phytosanitary legislation is not clear. Host availability and climate suitability suggest that southern EU regions extending from the Atlantic coast of Portugal through the Mediterranean would be suitable for B. insularis establishment. The introduction of B. insularis to such areas of the EU would likely cause impacts to St. Augustine grass, as already seen in Portugal. Measures to prevent further entry and spread are available. Options to reduce the impact of established populations are also available. B. insularis satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Euzophera semifuneralis (Lepidoptera: Pyralidae), the American plum borer for the EU. This insect is native to North America, reported from the United States, Canada and Mexico. Out of its native range it is only present in Türkiye. It has not been reported in the EU and is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It can complete from one up to three generations per year in its native range and is polyphagous, feeding on 22 genera in 16 plant families. Host plant species commonly found in the EU include black walnut (Juglans nigra), mulberry (Morus alba, M. nigra), olive (Olea europaea), almond (Prunus dulcis), apricot (P. armeniaca), peach (P. persica), plum (P. domestica), sweet cherry (P. avium), apple (Malus domestica), pear (Pyrus communis) and pomegranate (Punica granatum). E. semifuneralis is generally known as pest of trees affected by mechanical injuries, frost or canker diseases. The pest is also known to vector the fungus Ceratocystis fimbriata which is not known to occur in the EU. Climatic conditions and availability of host plants in some EU countries would allow this species to establish and spread. Impact in cultivated hosts including apples, plums, mulberries, almond, olive and ornamental broadleaf trees is anticipated. Phytosanitary measures are available to reduce the likelihood of entry and spread. E. semifuneralis meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Hoplolaimus galeatus (Nematoda: Hoplolaimidae) for the EU. H. galeatus belongs to the order Rhabditida, subfamily Hoplolaiminae. This nematode is not reported from the EU and is not included in the EU Commission Implementing Regulation 2019/2072. It is widely distributed in the USA and is also reported from South America, Africa, Asia and Australia. The identity of H. galeatus is clearly defined and methods for its identification are available. H. galeatus is polyphagous and natural hosts include barley, wheat, rye, red and white clover, alfalfa, cabbage, pine, spruce, oak, apple, grapevine, as well as various ornamental plants and turf grasses. These hosts are grown over vast areas of the EU. The climate of the EU is suitable for the establishment of H. galeatus. Pathways of entry are host plants for planting except seeds, but also soil as a contaminant. Soil import to the EU is prohibited and special requirements apply to import of machinery for agricultural/forestry purposes from third countries. Impact of the nematode is best known for North American plant species. The nematode has been reported to damage cotton, maize, soybean, pine, oak and turfgrass. Many of the hosts represent a considerable economic and environmental value to the EU. Therefore, the Panel concludes that H. galeatus satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The EFSA Panel on Plant Health conducted a pest categorisation of the avocado sunblotch viroid (ASBVd) for the EU. The identity of ASBVd, a member of the genus Avsunviroid (family Avsunviroidae) is clearly defined and detection and identification methods are available. The pathogen is not included in the EU Commission Implementing Regulation 2019/2072. ASBVd has been reported in Australia, Ghana, Guatemala, Israel, Mexico, Peru, South Africa, USA (California, Florida) and Venezuela. In the EU, it has been reported in Greece (Crete Island) and Spain. The pathogen could establish in the EU wherever avocado (Persea americana) is grown. The only known natural host of ASBVd is avocado to which it causes the severe 'avocado sunblotch' disease, characterised by white, yellow, red or necrotic depressed areas or scars on the fruit surface, bleached veins and petioles of the leaf, and rectangular cracking patterns in the bark of the old branches. Fruit yield and quality are severely diminished. ASBVd infects under experimental conditions a few more species in the family Lauraceae. The viroid is naturally transmitted at an extremely high rate by seeds (up to 100% in asymptomatically infected trees), but with a low efficiency by pollen (only to the produced seeds), and possibly through root grafts. Plants for planting, including seeds, and fresh avocado fruits were identified as the most relevant pathways for further entry of ASBVd into the EU. Avocado crops are cultivated in southern EU countries. Should the pest further enter and establish in the EU, impact on the production of avocado is expected. Phytosanitary measures are available to prevent entry and spread of the viroid in the EU. ASBVd fulfils the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Diplodia bulgarica, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects Malus domestica, M. sylvestris and Pyrus communis causing various symptoms such as canker, twig blight, gummosis, pre‐ and post‐harvest fruit rot, dieback and tree decline. The pathogen is present in Asia (India, Iran, Türkiye) and in non‐EU Europe (Serbia). Concerning the EU, the pathogen is present in Bulgaria and widespread in Germany. There is a key uncertainty on the geographical distribution of D. bulgarica worldwide and in the EU, because in the past, when molecular tools were not available, the pathogen might have been misidentified as other Diplodia species (e.g. D. intermedia, D. malorum, D. mutila, D. seriata) or other members of the Botryosphaeriaceae family affecting apple and pear based only on morphology and pathogenicity tests. Diplodia bulgarica is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting, other than seeds, fresh fruits, and bark and wood of host plants as well as soil and other plant‐growing media carrying plant debris are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors are favourable for the further establishment of the pathogen in the EU. In the areas of its present distribution, including Germany, the pathogen has a direct impact on cultivated hosts. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. Diplodia bulgarica satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Coleosporium asterum (Dietel) Sydow & P. Sydow, Coleosporium montanum (Arthur & F. Kern) and Coleosporium solidaginis (Schwein.) Thüm, three basidiomycete fungi belonging to the family Coleosporiaceae, causing rust diseases on Pinus spp. (aecial hosts) and on Asteraceae (telial hosts). Coleosporium asterum was described on Aster spp. in Japan and has been reported from China, Korea, France and Portugal. Coleosporium montanum is native to North America, has been introduced to Asia and has been reported from Austria on Symphyotrichum spp. Coleosporium solidaginis has been reported on Solidago spp. from North America, Asia and Europe (Switzerland and Germany). There is a key uncertainty about these reported distributions, due to the until recently accepted synonymy between these fungi and the lack of molecular studies. The pathogens are not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072, an implementing act of Regulation (EU) 2016/2031, or in any emergency plant health legislation. There are no reports of interceptions of C. asterum, C. montanum or C. solidaginis in the EU. The pathogens can further enter into, establish in and spread within the EU via host plants for planting, other than seeds and host plant parts (e.g. cut flowers, foliage, branches), other than fruits. Entry into and spread within the EU may also occur by natural means. Host availability and climate suitability in the EU are favourable for the establishment of the pathogens in areas where host plants in the Asteraceae and Pinaceae co‐exist. Impacts can be expected on both aecial and telial hosts. Phytosanitary measures are available to reduce the risk of further introduction and spread of the three pathogens in the EU. Coleosporium asterum, C. montanum and C. solidaginis satisfy the criteria that are within the remit of EFSA to assess for these species to be regarded as Union quarantine pests, but a key uncertainty exists about their EU distribution.

The EFSA Panel on Plant Health updated its 2017 pest categorisation of coconut cadang cadang viroid (CCCVd) for the EU territory due to new data on its host range. The identity of CCCVd, a member of the genus Cocadviroid (family Pospiviroidae), is established and detection and identification methods are available. It is included as a quarantine pest for the EU in the Commission Implementing Regulation (EU) 2019/2072. CCCVd has been reported from the Philippines and Malaysia. It is not known to be present in the EU. The host range of CCCVd is restricted to Arecaceae species (palms), in particular, coconut palm (Cocos nucifera) to which it causes a lethal disease. Oil palm (Elaeis guineensis) and buri palm (Corypha utan) are other natural hosts of CCCVd. Palm species of several genera, including Phoenix spp. and other species grown and/or cultivated in the EU, have been identified as potential hosts. The viroid is naturally transmitted at low rate by seeds and pollen and possibly by additional not yet identified natural transmission means. It can be transmitted through vegetative propagation applied to some palm species. Plants for planting including seeds of its hosts have been identified as the main entry pathway of CCCVd. Potential hosts of CCCVd are present in the EU, therefore establishment is possible. Should the pest establish in the EU, an impact is expected, with uncertainty on its magnitude. The Panel identified the susceptibility of palm species grown in the EU as a key uncertainty potentially affecting the conclusion of this pest categorisation. Nevertheless, the pest satisfies the criteria that are within the remit of EFSA to assess for this viroid to be regarded as potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Coleosporium eupatorii Arthur ex Cummins, a clearly defined heteroecious fungus of the family Coleosporiaceae, causing rust diseases on five‐needle Pinus spp. (aecial hosts) and on several genera of the Asteraceae family (telial hosts), such as Eupatorium spp. and Stevia spp. C. eupatorii is reported from Asia as well as North, Central and South America. It is not known to occur in the EU. The pathogen is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072 and has not been intercepted in the EU. The pathogen can be detected on its host plants by DNA sequencing. The main pathway for the entry of C. eupatorii into the EU is host plants for planting, other than seeds. In the EU, there is availability of aecial host plants, with Pinus peuce, P. strobus and P. cembra being the most important ones. There is a key uncertainty about whether European Eupatorium species (specifically E. cannabinum) are hosts of C. eupatorii and thus the ability of the pathogen to complete its life cycle, establish and spread in the EU. C. eupatorii could potentially spread within the EU by both natural and human‐assisted means. The introduction of C. eupatorii into the EU is expected to have an economic and environmental impact. Phytosanitary measures are available to prevent the introduction and spread of the pathogen in the EU. C. eupatorii satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Nilaparvata lugens (Hemiptera: Delphacidae), the brown planthopper, for the European Union. N. lugens is widespread in Asia where it is native; it also occurs in Oceania where it is naturalised. N. lugens is not known to be present in the EU and is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is a monophagous species and a major pest of rice (Oryza sativa). High populations of planthoppers cause leaves to initially turn orange yellow before becoming brown and dry and this is a condition called 'hopperburn' that kills the plant. N. lugens can also transmit plant viruses. It can complete 12 generations per year in tropical areas, where it resides year‐round. N. lugens can undertake long‐distance migration of up to 500 km from tropical areas to form transient populations in sub‐tropical and temperate areas but due to low temperatures and absence of rice plants during the winter it does not establish in such areas. Entry to the EU via migration is unlikely given the distance from tropical rice growing areas. A possible but unlikely potential pathway is the import of infested rice seedlings, although we have no evidence that such trade exists. In the EU, rice is mainly planted from seed; when transplanted, it is sourced locally. N. lugens is very unlikely to survive year‐round in the EU due to unsuitable climate and lack of hosts during the winter. Consequently, the pest is very unlikely to become established in the EU territory. Nevertheless, there are measures available to further reduce the likelihood of entry, establishment and spread of N. lugens within the EU. N. lugens does not satisfy the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Neoscytalidium dimidiatum, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects a wide range of woody perennial crops and ornamental plants causing symptoms such as leaf spot, shoot blight, branch dieback, canker, pre‐ and post‐harvest fruit rot, gummosis and root rot. The pathogen is present in Africa, Asia, North and South America, and Oceania. It has also been reported from Greece, Cyprus and Italy, with a restricted distribution. Nevertheless, there is a key uncertainty on the geographical distribution of N. dimidiatum worldwide and in the EU, because in the past, when molecular tools were not available, the two synanamorphs of the pathogen (Fusicoccum‐like and Scytalidium‐like) might have been misidentified based only on morphology and pathogenicity tests. N. dimidiatum is not included in Commission Implementing Regulation (EU) 2019/2072. Because of the wide host range of the pathogen, this pest categorisation focuses on those hosts for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequence analysis. Plants for planting, fresh fruits and bark and wood of host plants as well as soil and other plant growing media are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the further establishment of the pathogen. In the areas of its present distribution, including Italy, the pathogen has a direct impact on cultivated hosts. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. N. dimidiatum satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Takahashia japonica (Hemiptera: Sternorrhyncha: Coccidae), the Asian string cottony scale, for the EU. This insect is native to Japan, and it is now established in many countries in Asia. It was first recorded in the EU (Italy) in 2017 and has also been found in Croatia. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on broad‐leafed trees and shrubs assigned to 25 genera belonging to 17 families. Host plant species commonly found in EU include maple (Acer spp.), alder (Alnus japonica), silkworm mulberry (Morus alba), black mulberry (Morus nigra), quince (Cydonia oblonga), walnut (Juglans regia), cherry plum (Prunus cerasifera), apple (Malus domestica) and citrus (Citrus sp.). Climatic conditions and availability of host plants in southern and central EU countries have allowed this species to establish and spread. Impact in cultivated hosts including citrus, mulberries, quinces, apples, plums, forest trees, as well as ornamental plants, is anticipated. Phytosanitary measures are available to reduce the likelihood of entry and further spread. T. japonica meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Solenopsis invicta Butler (Hymenoptera: Formicidae) the red imported fire ant, for the EU territory. S. invicta is native to central South America and has spread to North and Central America, East Asia and Australia where it is recognised as a major invasive species causing serious environmental impacts to biodiversity and harming horticultural crops such as cabbage, eggplant and potatoes. It can girdle and kill young citrus trees. S. invicta is not listed as a Union quarantine pest in Annex II of Commission Implementing Regulation (EU) 2019/2072. However, the European Scientific Forum on Invasive Alien Species lists S. invicta as a species of Union concern (Commission Implementing Regulation (EU) 2022/1203). Like other ant species, S. invicta is a social insect commonly creating colonies in the soil. Long‐distance spread in the Americas has been attributed to nests being carried in soil accompanying plants for planting, or simply in soil alone. S. invicta could enter the EU via conveyances carrying a wide range of goods if the conveyance is contaminated with soil or has been in close contact with soil, and with plants for planting in soil or growing media. Climatic conditions in large parts of the southern EU are suitable for establishment and spread would occur when mated females disperse to form new colonies. If S. invicta established in the EU, losses to horticultural crops would be expected in addition to losses to biodiversity. The impacts of S. invicta go beyond plant health with the ant attacking new‐born, hatching, weak or sick animals. Stings can cause allergic reactions in humans and are a public health issue. However, such factors are outside the scope of a pest categorisation. S. invicta satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as saprophytes, or as plant growth promoting bacteria or biocontrol agents. It is also described as a clinical pathogen causing bacteraemia and sepsis or as a member of the gut microbiota of several insects. P. ananatis is the causal agent of different diseases affecting numerous crops: in particular, centre rot of onion, bacterial leaf blight and grain discoloration of rice, leaf spot disease of maize and eucalyptus blight/dieback. A few insect species have been described as vectors of P. ananatis, among them, Frankliniella fusca and Diabrotica virgifera virgifera. This bacterium is present in several countries in Europe, Africa, Asia, North and South America, and Oceania from tropical and subtropical regions to temperate areas worldwide. P. ananatis has been reported from the EU territory, both as pathogen on rice and maize and as an environmental, non‐pathogenic bacterium in rice marshes and poplar rhizosoil. It is not included in EU Commission Implementing Regulation 2019/2072. The pathogen can be detected on its host plants using direct isolation, or PCR‐based methods. The main pathway for the entry of the pathogen into the EU territory is host plants for planting, including seeds. In the EU, there is a large availability of host plants, with onion, maize, rice and strawberry being the most important ones. Therefore, disease outbreaks are possible almost at any latitude, except in the most northern regions. P. ananatis is not expected to have frequent or consistent impact on crop production and is not expected to have any environmental impact. Phytosanitary measures are available to mitigate the further introduction and spread of the pathogen into the EU on some hosts. The pest does not satisfy the criteria, which are within the remit for EFSA to evaluate whether the pest meets the definition of a Union quarantine pest. P. ananatis is probably widely distributed in different ecosystems in the EU. It may impact some specific hosts such as onions while on other hosts such as rice it has been reported as a seed microbiota without causing any impact and can even be beneficial to plant growth. Hence, the pathogenic nature of P. ananatis is not fully established. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Urocerus albicornis (Hymenoptera: Siricidae), the black horntail sawfly, for the territory of the EU. U. albicornis is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. U. albicornis occurs throughout Canada and continental USA and has established in northern Spain, and probably in southern France (based on two specimens caught in two sites) and Japan (based on one individual caught in one site). It attacks mostly stumps or fallen or weakened trees of at least 20 species of Pinaceae (Abies spp., Larix spp., Picea spp., Pinus spp., Pseudotsuga menziesii, Tsuga spp.) and of Cupressaceae (Thuja plicata). In Spain, the females fly between May and September with a peak in August and September. The eggs are deposited into the sapwood, together with mucus containing a venom and a white‐rot wood‐decay basidiomycete, either Amylostereum chailletii or A. areolatum. Each fungus is symbiotic with the insect. The larvae feed on wood infected by the fungus. All immature stages live in the host sapwood. In British Columbia, the lifecycle of the pest lasts 2 years but has not been fully characterised elsewhere. The wood of the host trees is impacted by decay due to the fungus, and structurally impaired by the larval galleries. U. albicornis can be carried in conifer wood, solid wood packaging material (SWPM) or plants for planting. Wood from North America is regulated by 2019/2072 (Annex VII) while SWPM is managed according to ISPM 15. The pathway plants for planting is largely closed by prohibition, with the exception of Thuja spp. Climatic conditions in several EU member states are conducive for establishment and the main host plants are widespread in those areas. Further spread and introduction of U. albicornis is likely to decrease the quality of host wood and may influence forest diversity by selectively affecting conifers. Phytosanitary measures are available to reduce the likelihood of additional entry and further spread, and there is a potential for biological control. Despite uncertainty regarding potential damage, U. albicornis satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The EFSA Panel on Plant Health performed a pest categorisation of Milviscutulus mangiferae (Hemiptera: Sternorrhyncha: Coccidae), the mango shield scale, for the EU. The native range of M. mangiferae is uncertain. This species occurs widely in tropical and warmer subtropical regions throughout the world. Within the EU, the pest has been recorded in Italy in a greenhouse at the Botanical Garden of Padua on mango trees imported from Florida (USA); however, its establishment remains uncertain. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on plant species belonging to more than 86 genera in more than 43 families including many crop and ornamental plants. It can be a serious pest of mango (Mangifera indica) and an occasional pest of a range of ornamental plants. Economically important crops in the EU such as citrus (Citrus spp.), avocado (Persea americana) and ornamentals such as hibiscus (Hibiscus spp.) and myrtle (Myrtus communis), are included in the host list of M. mangiferae. Reproduction of M. mangiferae is generally parthenogenetic and it completes two to three generations annually. Plants for planting, cut flowers and fruits provide potential pathways for entry into the EU. Climatic conditions in southern EU countries and host plant availability in those areas are conducive for establishment and spread. Establishment could also occur in heated greenhouses in cooler areas of the EU. The introduction of the mango shield scale is expected to have an economic impact in the EU through the reduction in yield, quality and commercial value of fruits and ornamental plants. Phytosanitary measures are available to reduce the likelihood of entry and further spread. M. mangiferae meets the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Coniella granati, a clearly defined fungus of the Order Diaporthales and the family Schizoparmaceae, described for the first time in 1876 as Phoma granatii and later named as Pilidiella granati. The pathogen mainly affects Punica granatum (pomegranate) and Rosa spp. (rose), causing fruit rot, shoot blight and cankers on crown and branches. The pathogen is present in North America, South America, as well as in Asia, Africa, Oceania and Eastern Europe and has also been reported in the EU (Greece, Hungary, Italy and Spain), where it is widespread in the major pomegranate growing areas. Coniella granati is not included in Commission Implementing Regulation (EU) 2019/2072 and there are no interceptions in the EU. This pest categorisation focused on those hosts for which the pathogen was detected and formally identified in natural conditions. Plants for planting, fresh fruits and as well as soil and other plant growing media are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the further establishment of the pathogen. In the area of its present distribution, including Italy and Spain, the pathogen has a direct impact in pomegranate orchards as well as during post‐harvest storage. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. Coniella granati does not satisfy the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest as it is present in several EU MSs.

The EFSA Panel on Plant Health conducted a pest categorisation of cowpea mosaic virus (CPMV) for the EU territory. The identity of CPMV, a member of the genus Comovirus (family Secoviridae), is established and detection and identification methods are available. The pathogen is not included in the Commission Implementing Regulation (EU) 2019/2072. It has been reported from the Americas, and several countries in Africa and Asia and it is not known to be present in the EU in natural conditions. CPMV is considered a major pathogen of cowpea on which it causes symptoms ranging from mild to severe mosaic, chlorosis and necrosis. The virus has been reported sporadically on some other cultivated species of the family Fabaceae, including soybean and some common bean varieties. CPMV is transmitted by cowpea seeds, with uncertainty on the transmission rate. There is uncertainty on seed transmission by other Fabaceae host species due to lack of information. CPMV is also transmitted by several beetle species, one of which, Diabrotica virgifera virgifera, is present in the EU. Seeds for sowing of cowpea are identified as the major entry pathway. The cultivated area and production of cowpea in the EU territory are mainly limited to local varieties cultivated at a small scale in Mediterranean EU Member States. Should the pest establish in the EU, an impact is expected on cowpea crops at local scale. There is high uncertainty on the potential impact that CPMV would cause on other natural hosts cultivated in the EU due to the lack of information from the areas of CPMV's current distribution. Despite the uncertainty concerning the potential impact on bean and soybean crops in the EU, CPMV satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Blissus insularis (Hemiptera: Heteroptera: Blissidae) for the European Union (EU) territory. B. insularis, known in the US as the southern chinch bug, primarily feeds on St. Augustine grass (Stenotaphrum secundatum, Poaceae, subfamily Panicoideae). This is a lawn grass grown in warm, tropical and subtropical regions of the world and which is widely grown in the southern US and also used in southern EU as a lawn and amenity grass. Adults and nymphs aggregate to feed at the base of the grass. B. insularis occurs in the southern continental US, Hawaii, Guam, Mexico, Central and South America, and across the Caribbean. In the EU, B. insularis was first detected in Portugal in 2019, where following a national survey, it has now been found in 10 municipalities across the central and southern parts of the country. The pathway for entry into Portugal is unknown. B. insularis is not a regulated pest in the EU. It could further enter and spread within the EU via the import and movement of host plants for planting. S. secundatum is vegetatively propagated because seed is largely sterile. Many Poaceae plants for planting are prohibited from entering the EU, other than some ornamental perennial grasses. Whether S. secundatum is considered an ornamental grass within phytosanitary legislation is not clear. Host availability and climate suitability suggest that southern EU regions extending from the Atlantic coast of Portugal through the Mediterranean would be suitable for B. insularis establishment. The introduction of B. insularis to such areas of the EU would likely cause impacts to St. Augustine grass, as already seen in Portugal. Measures to prevent further entry and spread are available. Options to reduce the impact of established populations are also available. B. insularis satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Hoplolaimus galeatus (Nematoda: Hoplolaimidae) for the EU. H. galeatus belongs to the order Rhabditida, subfamily Hoplolaiminae. This nematode is not reported from the EU and is not included in the EU Commission Implementing Regulation 2019/2072. It is widely distributed in the USA and is also reported from South America, Africa, Asia and Australia. The identity of H. galeatus is clearly defined and methods for its identification are available. H. galeatus is polyphagous and natural hosts include barley, wheat, rye, red and white clover, alfalfa, cabbage, pine, spruce, oak, apple, grapevine, as well as various ornamental plants and turf grasses. These hosts are grown over vast areas of the EU. The climate of the EU is suitable for the establishment of H. galeatus. Pathways of entry are host plants for planting except seeds, but also soil as a contaminant. Soil import to the EU is prohibited and special requirements apply to import of machinery for agricultural/forestry purposes from third countries. Impact of the nematode is best known for North American plant species. The nematode has been reported to damage cotton, maize, soybean, pine, oak and turfgrass. Many of the hosts represent a considerable economic and environmental value to the EU. Therefore, the Panel concludes that H. galeatus satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health conducted a pest categorisation of the avocado sunblotch viroid (ASBVd) for the EU. The identity of ASBVd, a member of the genus Avsunviroid (family Avsunviroidae) is clearly defined and detection and identification methods are available. The pathogen is not included in the EU Commission Implementing Regulation 2019/2072. ASBVd has been reported in Australia, Ghana, Guatemala, Israel, Mexico, Peru, South Africa, USA (California, Florida) and Venezuela. In the EU, it has been reported in Greece (Crete Island) and Spain. The pathogen could establish in the EU wherever avocado (Persea americana) is grown. The only known natural host of ASBVd is avocado to which it causes the severe ‘avocado sunblotch’ disease, characterised by white, yellow, red or necrotic depressed areas or scars on the fruit surface, bleached veins and petioles of the leaf, and rectangular cracking patterns in the bark of the old branches. Fruit yield and quality are severely diminished. ASBVd infects under experimental conditions a few more species in the family Lauraceae. The viroid is naturally transmitted at an extremely high rate by seeds (up to 100% in asymptomatically infected trees), but with a low efficiency by pollen (only to the produced seeds), and possibly through root grafts. Plants for planting, including seeds, and fresh avocado fruits were identified as the most relevant pathways for further entry of ASBVd into the EU. Avocado crops are cultivated in southern EU countries. Should the pest further enter and establish in the EU, impact on the production of avocado is expected. Phytosanitary measures are available to prevent entry and spread of the viroid in the EU. ASBVd fulfils the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Euzophera semifuneralis (Lepidoptera: Pyralidae), the American plum borer for the EU. This insect is native to North America, reported from the United States, Canada and Mexico. Out of its native range it is only present in Türkiye. It has not been reported in the EU and is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It can complete from one up to three generations per year in its native range and is polyphagous, feeding on 22 genera in 16 plant families. Host plant species commonly found in the EU include black walnut (Juglans nigra), mulberry (Morus alba, M. nigra), olive (Olea europaea), almond (Prunus dulcis), apricot (P. armeniaca), peach (P. persica), plum (P. domestica), sweet cherry (P. avium), apple (Malus domestica), pear (Pyrus communis) and pomegranate (Punica granatum). E. semifuneralis is generally known as pest of trees affected by mechanical injuries, frost or canker diseases. The pest is also known to vector the fungus Ceratocystis fimbriata which is not known to occur in the EU. Climatic conditions and availability of host plants in some EU countries would allow this species to establish and spread. Impact in cultivated hosts including apples, plums, mulberries, almond, olive and ornamental broadleaf trees is anticipated. Phytosanitary measures are available to reduce the likelihood of entry and spread. E. semifuneralis meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Coleosporium asterum (Dietel) Sydow & P. Sydow, Coleosporium montanum (Arthur & F. Kern) and Coleosporium solidaginis (Schwein.) Thüm, three basidiomycete fungi belonging to the family Coleosporiaceae, causing rust diseases on Pinus spp. (aecial hosts) and on Asteraceae (telial hosts). Coleosporium asterum was described on Aster spp. in Japan and has been reported from China, Korea, France and Portugal. Coleosporium montanum is native to North America, has been introduced to Asia and has been reported from Austria on Symphyotrichum spp. Coleosporium solidaginis has been reported on Solidago spp. from North America, Asia and Europe (Switzerland and Germany). There is a key uncertainty about these reported distributions, due to the until recently accepted synonymy between these fungi and the lack of molecular studies. The pathogens are not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072, an implementing act of Regulation (EU) 2016/2031, or in any emergency plant health legislation. There are no reports of interceptions of C. asterum, C. montanum or C. solidaginis in the EU. The pathogens can further enter into, establish in and spread within the EU via host plants for planting, other than seeds and host plant parts (e.g. cut flowers, foliage, branches), other than fruits. Entry into and spread within the EU may also occur by natural means. Host availability and climate suitability in the EU are favourable for the establishment of the pathogens in areas where host plants in the Asteraceae and Pinaceae co‐exist. Impacts can be expected on both aecial and telial hosts. Phytosanitary measures are available to reduce the risk of further introduction and spread of the three pathogens in the EU. Coleosporium asterum, C. montanum and C. solidaginis satisfy the criteria that are within the remit of EFSA to assess for these species to be regarded as Union quarantine pests, but a key uncertainty exists about their EU distribution.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Diplodia bulgarica, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects Malus domestica, M. sylvestris and Pyrus communis causing various symptoms such as canker, twig blight, gummosis, pre‐ and post‐harvest fruit rot, dieback and tree decline. The pathogen is present in Asia (India, Iran, Türkiye) and in non‐EU Europe (Serbia). Concerning the EU, the pathogen is present in Bulgaria and widespread in Germany. There is a key uncertainty on the geographical distribution of D. bulgarica worldwide and in the EU, because in the past, when molecular tools were not available, the pathogen might have been misidentified as other Diplodia species (e.g. D. intermedia, D. malorum, D. mutila, D. seriata) or other members of the Botryosphaeriaceae family affecting apple and pear based only on morphology and pathogenicity tests. Diplodia bulgarica is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting, other than seeds, fresh fruits, and bark and wood of host plants as well as soil and other plant‐growing media carrying plant debris are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors are favourable for the further establishment of the pathogen in the EU. In the areas of its present distribution, including Germany, the pathogen has a direct impact on cultivated hosts. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. Diplodia bulgarica satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Solenopsis invicta Butler (Hymenoptera: Formicidae) the red imported fire ant, for the EU territory. S. invicta is native to central South America and has spread to North and Central America, East Asia and Australia where it is recognised as a major invasive species causing serious environmental impacts to biodiversity and harming horticultural crops such as cabbage, eggplant and potatoes. It can girdle and kill young citrus trees. S. invicta is not listed as a Union quarantine pest in Annex II of Commission Implementing Regulation (EU) 2019/2072. However, the European Scientific Forum on Invasive Alien Species lists S. invicta as a species of Union concern (Commission Implementing Regulation (EU) 2022/1203). Like other ant species, S. invicta is a social insect commonly creating colonies in the soil. Long‐distance spread in the Americas has been attributed to nests being carried in soil accompanying plants for planting, or simply in soil alone. S. invicta could enter the EU via conveyances carrying a wide range of goods if the conveyance is contaminated with soil or has been in close contact with soil, and with plants for planting in soil or growing media. Climatic conditions in large parts of the southern EU are suitable for establishment and spread would occur when mated females disperse to form new colonies. If S. invicta established in the EU, losses to horticultural crops would be expected in addition to losses to biodiversity. The impacts of S. invicta go beyond plant health with the ant attacking new‐born, hatching, weak or sick animals. Stings can cause allergic reactions in humans and are a public health issue. However, such factors are outside the scope of a pest categorisation. S. invicta satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Neoscytalidium dimidiatum, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects a wide range of woody perennial crops and ornamental plants causing symptoms such as leaf spot, shoot blight, branch dieback, canker, pre‐ and post‐harvest fruit rot, gummosis and root rot. The pathogen is present in Africa, Asia, North and South America, and Oceania. It has also been reported from Greece, Cyprus and Italy, with a restricted distribution. Nevertheless, there is a key uncertainty on the geographical distribution of N. dimidiatum worldwide and in the EU, because in the past, when molecular tools were not available, the two synanamorphs of the pathogen (Fusicoccum‐like and Scytalidium‐like) might have been misidentified based only on morphology and pathogenicity tests. N. dimidiatum is not included in Commission Implementing Regulation (EU) 2019/2072. Because of the wide host range of the pathogen, this pest categorisation focuses on those hosts for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequence analysis. Plants for planting, fresh fruits and bark and wood of host plants as well as soil and other plant growing media are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the further establishment of the pathogen. In the areas of its present distribution, including Italy, the pathogen has a direct impact on cultivated hosts. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. N. dimidiatum satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Nilaparvata lugens (Hemiptera: Delphacidae), the brown planthopper, for the European Union. N. lugens is widespread in Asia where it is native; it also occurs in Oceania where it is naturalised. N. lugens is not known to be present in the EU and is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is a monophagous species and a major pest of rice (Oryza sativa). High populations of planthoppers cause leaves to initially turn orange yellow before becoming brown and dry and this is a condition called ‘hopperburn’ that kills the plant. N. lugens can also transmit plant viruses. It can complete 12 generations per year in tropical areas, where it resides year‐round. N. lugens can undertake long‐distance migration of up to 500 km from tropical areas to form transient populations in sub‐tropical and temperate areas but due to low temperatures and absence of rice plants during the winter it does not establish in such areas. Entry to the EU via migration is unlikely given the distance from tropical rice growing areas. A possible but unlikely potential pathway is the import of infested rice seedlings, although we have no evidence that such trade exists. In the EU, rice is mainly planted from seed; when transplanted, it is sourced locally. N. lugens is very unlikely to survive year‐round in the EU due to unsuitable climate and lack of hosts during the winter. Consequently, the pest is very unlikely to become established in the EU territory. Nevertheless, there are measures available to further reduce the likelihood of entry, establishment and spread of N. lugens within the EU. N. lugens does not satisfy the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Takahashia japonica (Hemiptera: Sternorrhyncha: Coccidae), the Asian string cottony scale, for the EU. This insect is native to Japan, and it is now established in many countries in Asia. It was first recorded in the EU (Italy) in 2017 and has also been found in Croatia. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on broad‐leafed trees and shrubs assigned to 25 genera belonging to 17 families. Host plant species commonly found in EU include maple (Acer spp.), alder (Alnus japonica), silkworm mulberry (Morus alba), black mulberry (Morus nigra), quince (Cydonia oblonga), walnut (Juglans regia), cherry plum (Prunus cerasifera), apple (Malus domestica) and citrus (Citrus sp.). Climatic conditions and availability of host plants in southern and central EU countries have allowed this species to establish and spread. Impact in cultivated hosts including citrus, mulberries, quinces, apples, plums, forest trees, as well as ornamental plants, is anticipated. Phytosanitary measures are available to reduce the likelihood of entry and further spread. T. japonica meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health updated its 2017 pest categorisation of coconut cadang cadang viroid (CCCVd) for the EU territory due to new data on its host range. The identity of CCCVd, a member of the genus Cocadviroid (family Pospiviroidae), is established and detection and identification methods are available. It is included as a quarantine pest for the EU in the Commission Implementing Regulation (EU) 2019/2072. CCCVd has been reported from the Philippines and Malaysia. It is not known to be present in the EU. The host range of CCCVd is restricted to Arecaceae species (palms), in particular, coconut palm (Cocos nucifera) to which it causes a lethal disease. Oil palm (Elaeis guineensis) and buri palm (Corypha utan) are other natural hosts of CCCVd. Palm species of several genera, including Phoenix spp. and other species grown and/or cultivated in the EU, have been identified as potential hosts. The viroid is naturally transmitted at low rate by seeds and pollen and possibly by additional not yet identified natural transmission means. It can be transmitted through vegetative propagation applied to some palm species. Plants for planting including seeds of its hosts have been identified as the main entry pathway of CCCVd. Potential hosts of CCCVd are present in the EU, therefore establishment is possible. Should the pest establish in the EU, an impact is expected, with uncertainty on its magnitude. The Panel identified the susceptibility of palm species grown in the EU as a key uncertainty potentially affecting the conclusion of this pest categorisation. Nevertheless, the pest satisfies the criteria that are within the remit of EFSA to assess for this viroid to be regarded as potential Union quarantine pest.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Coleosporium eupatorii Arthur ex Cummins, a clearly defined heteroecious fungus of the family Coleosporiaceae, causing rust diseases on five‐needle Pinus spp. (aecial hosts) and on several genera of the Asteraceae family (telial hosts), such as Eupatorium spp. and Stevia spp. C. eupatorii is reported from Asia as well as North, Central and South America. It is not known to occur in the EU. The pathogen is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072 and has not been intercepted in the EU. The pathogen can be detected on its host plants by DNA sequencing. The main pathway for the entry of C. eupatorii into the EU is host plants for planting, other than seeds. In the EU, there is availability of aecial host plants, with Pinus peuce, P. strobus and P. cembra being the most important ones. There is a key uncertainty about whether European Eupatorium species (specifically E. cannabinum) are hosts of C. eupatorii and thus the ability of the pathogen to complete its life cycle, establish and spread in the EU. C. eupatorii could potentially spread within the EU by both natural and human‐assisted means. The introduction of C. eupatorii into the EU is expected to have an economic and environmental impact. Phytosanitary measures are available to prevent the introduction and spread of the pathogen in the EU. C. eupatorii satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Urocerus albicornis (Hymenoptera: Siricidae), the black horntail sawfly, for the territory of the EU. U. albicornis is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. U. albicornis occurs throughout Canada and continental USA and has established in northern Spain, and probably in southern France (based on two specimens caught in two sites) and Japan (based on one individual caught in one site). It attacks mostly stumps or fallen or weakened trees of at least 20 species of Pinaceae (Abies spp., Larix spp., Picea spp., Pinus spp., Pseudotsuga menziesii, Tsuga spp.) and of Cupressaceae (Thuja plicata). In Spain, the females fly between May and September with a peak in August and September. The eggs are deposited into the sapwood, together with mucus containing a venom and a white‐rot wood‐decay basidiomycete, either Amylostereum chailletii or A. areolatum. Each fungus is symbiotic with the insect. The larvae feed on wood infected by the fungus. All immature stages live in the host sapwood. In British Columbia, the lifecycle of the pest lasts 2 years but has not been fully characterised elsewhere. The wood of the host trees is impacted by decay due to the fungus, and structurally impaired by the larval galleries. U. albicornis can be carried in conifer wood, solid wood packaging material (SWPM) or plants for planting. Wood from North America is regulated by 2019/2072 (Annex VII) while SWPM is managed according to ISPM 15. The pathway plants for planting is largely closed by prohibition, with the exception of Thuja spp. Climatic conditions in several EU member states are conducive for establishment and the main host plants are widespread in those areas. Further spread and introduction of U. albicornis is likely to decrease the quality of host wood and may influence forest diversity by selectively affecting conifers. Phytosanitary measures are available to reduce the likelihood of additional entry and further spread, and there is a potential for biological control. Despite uncertainty regarding potential damage, U. albicornis satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Pantoea ananatis, a Gram‐negative bacterium belonging to the Erwiniaceae family. P. ananatis is a well‐defined taxonomic unit; nonetheless, its pathogenic nature is not well defined and non‐pathogenic populations are known to occupy several, very different environmental niches as saprophytes, or as plant growth promoting bacteria or biocontrol agents. It is also described as a clinical pathogen causing bacteraemia and sepsis or as a member of the gut microbiota of several insects. P. ananatis is the causal agent of different diseases affecting numerous crops: in particular, centre rot of onion, bacterial leaf blight and grain discoloration of rice, leaf spot disease of maize and eucalyptus blight/dieback. A few insect species have been described as vectors of P. ananatis, among them, Frankliniella fusca and Diabrotica virgifera virgifera. This bacterium is present in several countries in Europe, Africa, Asia, North and South America, and Oceania from tropical and subtropical regions to temperate areas worldwide. P. ananatis has been reported from the EU territory, both as pathogen on rice and maize and as an environmental, non‐pathogenic bacterium in rice marshes and poplar rhizosoil. It is not included in EU Commission Implementing Regulation 2019/2072. The pathogen can be detected on its host plants using direct isolation, or PCR‐based methods. The main pathway for the entry of the pathogen into the EU territory is host plants for planting, including seeds. In the EU, there is a large availability of host plants, with onion, maize, rice and strawberry being the most important ones. Therefore, disease outbreaks are possible almost at any latitude, except in the most northern regions. P. ananatis is not expected to have frequent or consistent impact on crop production and is not expected to have any environmental impact. Phytosanitary measures are available to mitigate the further introduction and spread of the pathogen into the EU on some hosts. The pest does not satisfy the criteria, which are within the remit for EFSA to evaluate whether the pest meets the definition of a Union quarantine pest. P. ananatis is probably widely distributed in different ecosystems in the EU. It may impact some specific hosts such as onions while on other hosts such as rice it has been reported as a seed microbiota without causing any impact and can even be beneficial to plant growth. Hence, the pathogenic nature of P. ananatis is not fully established.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Milviscutulus mangiferae (Hemiptera: Sternorrhyncha: Coccidae), the mango shield scale, for the EU. The native range of M. mangiferae is uncertain. This species occurs widely in tropical and warmer subtropical regions throughout the world. Within the EU, the pest has been recorded in Italy in a greenhouse at the Botanical Garden of Padua on mango trees imported from Florida (USA); however, its establishment remains uncertain. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is polyphagous, feeding on plant species belonging to more than 86 genera in more than 43 families including many crop and ornamental plants. It can be a serious pest of mango (Mangifera indica) and an occasional pest of a range of ornamental plants. Economically important crops in the EU such as citrus (Citrus spp.), avocado (Persea americana) and ornamentals such as hibiscus (Hibiscus spp.) and myrtle (Myrtus communis), are included in the host list of M. mangiferae. Reproduction of M. mangiferae is generally parthenogenetic and it completes two to three generations annually. Plants for planting, cut flowers and fruits provide potential pathways for entry into the EU. Climatic conditions in southern EU countries and host plant availability in those areas are conducive for establishment and spread. Establishment could also occur in heated greenhouses in cooler areas of the EU. The introduction of the mango shield scale is expected to have an economic impact in the EU through the reduction in yield, quality and commercial value of fruits and ornamental plants. Phytosanitary measures are available to reduce the likelihood of entry and further spread. M. mangiferae meets the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Panel on Plant Health conducted a pest categorisation of cowpea mosaic virus (CPMV) for the EU territory. The identity of CPMV, a member of the genus Comovirus (family Secoviridae), is established and detection and identification methods are available. The pathogen is not included in the Commission Implementing Regulation (EU) 2019/2072. It has been reported from the Americas, and several countries in Africa and Asia and it is not known to be present in the EU in natural conditions. CPMV is considered a major pathogen of cowpea on which it causes symptoms ranging from mild to severe mosaic, chlorosis and necrosis. The virus has been reported sporadically on some other cultivated species of the family Fabaceae, including soybean and some common bean varieties. CPMV is transmitted by cowpea seeds, with uncertainty on the transmission rate. There is uncertainty on seed transmission by other Fabaceae host species due to lack of information. CPMV is also transmitted by several beetle species, one of which, Diabrotica virgifera virgifera, is present in the EU. Seeds for sowing of cowpea are identified as the major entry pathway. The cultivated area and production of cowpea in the EU territory are mainly limited to local varieties cultivated at a small scale in Mediterranean EU Member States. Should the pest establish in the EU, an impact is expected on cowpea crops at local scale. There is high uncertainty on the potential impact that CPMV would cause on other natural hosts cultivated in the EU due to the lack of information from the areas of CPMV's current distribution. Despite the uncertainty concerning the potential impact on bean and soybean crops in the EU, CPMV satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

Abstract The EFSA Plant Health Panel performed a pest categorisation of Coniella granati, a clearly defined fungus of the Order Diaporthales and the family Schizoparmaceae, described for the first time in 1876 as Phoma granatii and later named as Pilidiella granati. The pathogen mainly affects Punica granatum (pomegranate) and Rosa spp. (rose), causing fruit rot, shoot blight and cankers on crown and branches. The pathogen is present in North America, South America, as well as in Asia, Africa, Oceania and Eastern Europe and has also been reported in the EU (Greece, Hungary, Italy and Spain), where it is widespread in the major pomegranate growing areas. Coniella granati is not included in Commission Implementing Regulation (EU) 2019/2072 and there are no interceptions in the EU. This pest categorisation focused on those hosts for which the pathogen was detected and formally identified in natural conditions. Plants for planting, fresh fruits and as well as soil and other plant growing media are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the further establishment of the pathogen. In the area of its present distribution, including Italy and Spain, the pathogen has a direct impact in pomegranate orchards as well as during post‐harvest storage. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. Coniella granati does not satisfy the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest as it is present in several EU MSs.

The EFSA Panel on Plant Health performed a pest categorisation of Resseliella maxima (Diptera: Cecidomyiidae), the soybean gall midge, for the EU. This midge was first described in 2018 and is widespread in north‐western United States. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. Larvae feed on and develop in soybean (Glycine max, Fabaceae), and possibly in two other Fabaceae, sweet clover (Melilotus officinalis) and alfalfa/lucerne (Medicago sativa). Feeding damage results in dark brown or black areas on the stems which become weak and can break near the soil; heavy infestations can cause plant death. R. maxima adults live only a few days and adult females lay eggs within 24 h after emergence. Larvae of R. maxima overwinter in the soil as third instars in silken cocoons. The main natural dispersal stage is the adult, which can fly. Freshly cut host plants for animal feed contaminated with larvae provide a potential pathway for entry into the EU. However, there is great uncertainty as to whether such plants are imported from USA states where R. maxima occurs. Climatic conditions and host availability in central‐western EU MS are favourable for outdoor establishment. Phytosanitary measures are available to reduce the likelihood of entry and spread. Except for the uncertainty concerning the likelihood of entry, R. maxima satisfies the other criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The EFSA Panel on Plant Health performed a pest categorisation of Nipaecoccus viridis (Hemiptera: Sternorrhyncha: Pseudococcidae), the spherical scale, for the EU. It is of Asian origin and occurs widely in southern Asia, Africa and tropical Australia. It has been introduced to a few countries in the Americas. In the Mediterranean basin it is found in Algeria, Egypt, Israel, Syria and Turkey, where it is limited to the Marmara region. It has not been reported within the EU. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It reproduces sexually, has three generations each year in citrus orchards in South Africa, and all stages can overwinter. First instar nymphs may move to neighbouring plants by crawling or be passively dispersed by wind or hitchhiking on clothing, equipment or animals. It is highly polyphagous, feeding on plants in 115 genera and 46 families. It is an important pest of citrus (Citrus spp.), cotton (Gossypium spp.), mango (Mangifera indica), avocado (Persea americana) and stored potatoes (Solanum tuberosum). It also feeds on a wide range of other fruit (apple Malus domestica, olive Olea europea, pear Pyrus communis and grape Vitis vinifera) and vegetable crops (tomato Solanum lycopersicum), and ornamental plants (roses, Rosa spp.) that are widely grown in the EU. Plants for planting, fruits, vegetables, and cut flowers are the main potential pathways for entry of N. viridis into the EU. Climatic conditions and availability of host plants in southern parts of the EU where there are few days of frost each year would likely allow this species to successfully establish and spread. Reductions in yield and quality of cultivated hosts including avocado, citrus, cotton and mango is anticipated if establishment occurs. Phytosanitary measures are available to reduce the likelihood of entry and spread. N. viridis meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Icerya aegyptiaca (Hemiptera: Sternorrhyncha: Monophlebidae), the Egyptian fluted scale, for the EU. This insect is established in several countries in tropical and subtropical regions of the world. Within the EU, the pest has not been reported. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is highly polyphagous, feeding on plants in 128 genera and 66 families, with some preference for avocado (Persea americana), banana (Musa sp.), citrus (Citrus spp.), coconut (Coccos nucifera), common pear (Pyrus communis), fig (Ficus spp.), guava (Psidium guajava), maize (Zea mays), mango (Mangifera indica), white mulberry (Morus alba), and grapevine (Vitis vinifera). It has also been recorded feeding on tomato (Solanum lycopersicum), as well as on ornamental plants. Plants for planting and fruits, vegetables and cut flowers are the main potential pathways for entry of I. aegyptiaca into the EU. Climatic conditions and availability of host plants in parts of the EU where there are very few days of frost each year would likely allow this species to successfully establish and spread. Economic impact in cultivated hosts including citrus, grapes, maize, peppers, sunflowers, tomatoes and ornamental crops is anticipated if establishment occurs. Phytosanitary measures are available to reduce the likelihood of entry and spread. I. aegyptiaca meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Xylella taiwanensis, a Gram‐negative bacterium belonging to the Xanthomonadaceae. The pathogen is a well‐defined taxonomic entity, and it is the causal agent of the pear leaf scorch. X. taiwanensis is present in subtropical and temperate areas of the island of Taiwan, where it affects low chilling pear cultivars of the species Pyrus pyrifolia (Asian pear). No other plant species are reported to be affected by the pathogen. The pathogen is not known to be present in the EU territory and it is not included in the Commission Implementing Regulation (EU) 2019/2072. The main pathway for the entry of the pathogen into the EU territory is host plants for planting (except seeds); another possible pathway might be represented by putative insect vectors, though their identity remains unknown. The cultivated area of P. pyrifolia in the EU territory is very limited. Conversely, the genetically related P. communis is widely cultivated in most EU Member States and there is no information so far on the susceptibility of its several cultivars. Should the pest establish in the EU, economic impact is expected, provided that suitable insect vectors are present and P. communis is as susceptible to infection as P. pyrifolia. Phytosanitary measures are available to prevent the introduction and spread of the pathogen into the EU, since plants for planting from Taiwan is a closed pathway; nonetheless, putative vectors, if confirmed and identified, may represent an additional risk of the pathogen's introduction and spread. The lack of knowledge on whether X. taiwanensis can infect P. communis, the identity and presence of suitable vectors in the EU lead to key uncertainties on entry, establishment, spread and impact. X. taiwanensis satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

Navel orangeworm, Amyelois transitella (Walker) (Lepidoptera Pyralidae), satisfies the criteria that are within the remit of the European Food Safety Authority (EFSA) to assess this species as a potential Union quarantine pest. A. transitella occurs in North, Central and South America. This species has been cited as present in Italy, Austria and Germany; however, no records was found, and it may also refer to an interception, the pest does not seem to be established in Europe. Should A. transitella arrive in the EU, the availability of hosts and occurrence of potentially suitable climates would be conducive for establishment. Because of the economic importance of this species, morphological characters, biological notes and seasonal ecology are reported. [ABSTRACT FROM AUTHOR]

The EFSA Plant Health Panel performed a pest categorisation of Coleosporium phellodendri Kom., a basidiomycete fungus belonging to the order Pucciniales, causing rust diseases on Pinus spp. (aecial host) and on Phellodendron spp. (telial host). C. phellodendri has been reported only from Asia (namely, China, Republic of Korea, Japan and Russia) and is not known to be present in the EU territory. The pathogen is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072, an implementing act of Regulation (EU) 2016/2031, or in any emergency plant health legislation. The pathogen could enter into, become established in, and spread within the EU territory via host plants for planting and host plant parts (e.g. foliage, branches) other than seeds and fruits, respectively. Spread within the EU territory may also occur by natural means if Phellodendron spp. were present. Availability of the Pinus spp. and climate suitability factors occurring in the EU are favourable for the establishment of the pathogen in areas where Phellodendron spp. are also present. Phytosanitary measures are available to prevent the introduction and spread of the pathogen in the EU. C. phellodendri does not satisfy all the criteria assessed by EFSA for consideration as a Union quarantine pest as no economic and environmental impact of this pathogen is expected without widespread presence of Phellodendron spp. in the EU.

The EFSA Panel on Plant Health performed a pest categorisation of Penthimiola bella (Hemiptera: Cicadellidae), the citrus leafhopper, for the European Union (EU). P. bella is native to the Afrotropical region; it has spread to Israel (first reported in 1974), Lebanon, and was reported from Morocco in 2018. Within the EU, P. bella is established in Portugal (Algarve) where it was first found on sweet oranges in 2012, and then in Spain in 2020, also on sweet oranges. P. bella is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is a polyphagous species reported, among cultivated hosts, on sweet orange, grapefruit and avocado. It is also described as being found on unspecified trees and bushes in savannahs, mountain forests and rain forests in Africa. Climatic conditions in some parts of southern EU countries are favourable and host plants are available in those areas to support establishment and spread. Despite being present in Portugal for over 10 years, there is a lack of evidence of impacts; hence, the magnitude of impact following introduction is uncertain. Nevertheless, in South Africa, P. bella was reported as being an economically important pest of citrus and to cause damage to avocado fruit during the early stages of development. Phytosanitary measures are available to reduce the likelihood of entry and further spread. Except for having uncertain economic or environmental impacts as a result of its introduction, P. bella satisfies all the other criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The EFSA Plant Health Panel performed a pest categorisation of Stenocarpella maydis, a clearly defined fungus causing seedling blight, stalk and ear rot in maize, its only confirmed main host. The pathogen occurs in many countries of North, Central and South America, Africa, Asia and Oceania where maize is grown commercially. It is present in the EU with restricted distribution (Czech Republic and Spain). Stenocarpella maydis is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting (maize seeds) is the main pathway of entry and spread in the EU. Host availability and climate are favourable for the establishment of the pathogen in maize‐growing areas of the EU. The pathogen has a direct impact on yield and quality of maize production. Phytosanitary measures are available to mitigate further introduction and spread of the pathogen into the EU. The Panel concludes that S. maydis satisfies all the criteria to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Matsucoccus massonianae (Hemiptera: Matsucoccidae), the Massonian pine bast scale, for the EU territory. M. massonianae occurs in western China and has been reported as a pest of Pinus massoniana (Chinese red pine) and P. thunbergii (Japanese black pine). These hosts occur in the EU as ornamental/amenity trees. Other scales in the Matsucoccus genus feed on a variety of Pinus species and the host range of M. massonianae could be wider than is currently recorded. There is one generation per year. All stages occur on the branches and stems of hosts with developing nymphs and adult females feeding under the bark on the phloem vessels of the host. Symptoms include the yellowing/browning of host needles, early needle drop, desiccation of shoots and bark necrosis. The most serious infestations occur in hosts aged 8–25 years old and there can be some host mortality. In principle, host plants for planting and plant products such as cut branches and wood with bark could provide entry pathways into the EU. However, prohibitions on the import of Pinus from non‐European third countries close these pathways. In China, M. massonianae occurs in regions with temperate humid conditions and hot summers. These conditions are also found in parts of southern EU. Were M. massonianae to establish in the EU, it is conceivable that it could expand its host range; however, this remains uncertain. M. massonianae satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. Some uncertainty exists over the magnitude of potential impacts. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Aonidiella orientalis (Hemiptera: Diaspididae), the oriental scale, for the EU. A. orientalis is a species mostly occurring in tropical and subtropical areas. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It is a polyphagous species, with hosts in more than 160 plant genera belonging to more than 70 families. Numerous important crops suffer economic losses from A. orientalis such as citrus, figs, mangoes, papayas, bananas, palms, tea and some ornamentals. A. orientalis has also been recorded on several other crops which are important for the EU such as cotton, apricots, peaches and grapes, but there are no records of economic impact on these hosts. This scale insect reproduces rapidly and may reach high population density between 15 and 30°C. In the tropics, the scale breeds continuously, generations overlap and all life stages coexist. In Queensland, Australia, A. orientalis can have up to six generations each year. The main natural dispersal stage is the first instar which crawls over the natal host plant or to adjacent host plants and can be dispersed further by wind. Plants for planting, vegetables, cut flowers and fruits provide potential pathways for entry into the EU. Between 1997 and 2019, the UK intercepted A. orientalis more than 120 times, most frequently on mangoes and guava fruit. Climatic conditions and host availability in southern EU MS are favourable for outdoor establishment. Phytosanitary measures are available to reduce the likelihood of entry and spread. The main uncertainties include the area of establishment and magnitude of impact. A. orientalis meets the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

The EFSA Panel on Plant Health performed a pest categorisation of Neomaskellia andropogonis (Hemiptera: Aleyrodidae), the sugarcane whitefly, for the EU territory. N. andropogonis is a tropical and subtropical species that originates in south central Asia and has recently established in Iran and Iraq. N. andropogonis is not listed in Commission Implementing Regulation (EU) 2019/2072. It is oligophagous on Poaceae and most frequently reported on sugarcane (Saccharum officinarum), on which it has become an important emerging pest in western Iran. The larvae feed on the foliage and stalks and can cause a reduction of photosynthesis rate and growth. In heavy infestations, the sugar purity and content are greatly decreased. Honeydew egested by feeding N. andropogonis larvae can promote the growth of black sooty mould over the host. No evidence was found indicating economic damage to other grasses. The ornamental grass hosts Andropogon sp. and Imperata cylindrica are ornamental grasses in the subfamily Panicoideae and are exempt from a general prohibition on Poaceae entering the EU and together with fresh sugarcane, provide potential pathways for entry. An estimated threshold for development from egg to adult of 7.2°C with approximately 500 degree days required for a generation suggests that climatic conditions, together with the availability of grass hosts in the southern EU, would support establishment. Adults disperse naturally by flying and all stages can be moved over long distances by the trade of infested plant material. The pest has the potential to impact sugarcane production in Portugal and Spain. N. andropogonis satisfies all of the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. However, this conclusion has high uncertainties regarding the likelihood of entry and the magnitude of potential impact within the EU as the insect is only recorded as an economically important pest in Iran, and its host range is poorly known and understood.

The EFSA Panel on Plant Health performed a pest categorisation of Dendrolimus spectabilis (Lepidoptera: Lasiocampidae), a moth, also known as the Japanese pine caterpillar, for the European Union (EU). D. spectabilis is native to China, Japan and Korea. Its larvae primarily feed on the needles of Pinus densiflora and P. thunbergii and can also feed on P. strobus, P. rigida, P. taeda and P. tabuliformis. The pest can have one or two generations per year; winter is mostly spent as fifth instar larvae in the soil. Adults emerge in July and August and females lay egg masses of 200–300 eggs on coniferous host needles. Natural enemies are described as significant factors of population density changes in Japan and the Republic of Korea. The pest can be detected visually, and there are morphological keys as well as molecular markers allowing identification. D. spectabilis could enter the EU, either as eggs, larvae or pupae in the foliage of plants for planting or cut branches, as larvae on wood with bark or as overwintering larvae in the litter of potted plants. However, Annex VI of Regulation 2019/2072 prohibits the introduction of D. spectabilis hosts from countries and areas where the pest occurs. D. spectabilis occurs in climatic zones that are found in the EU, and the fact that it attacks the North American P. strobus, P. taeda and P. rigida in its Asian native area suggests a potential to shift to local conifer species in the EU territory. There is uncertainty regarding the magnitude of economic and environmental impact of D. spectabilis on conifer species commonly occurring in the EU. Notwithstanding this uncertainty, D. spectabilis satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.

The EFSA Panel on Plant Health conducted a pest categorisation of chickpea chlorotic dwarf virus (CpCDV) for the EU territory. The identity of CpCDV, a member of the genus Mastrevirus (family Geminiviridae) is established. Reliable detection and identification methods are available. The pathogen is not included in the EU Commission Implementing Regulation 2019/2072. CpCDV has been reported in Africa, Asia and Oceania. It has not been reported in the EU. CpCDV infects plant species in the family Fabaceae and several species of other families (Amaranthaceae, Brassicaceae, Caricaceae, Cucurbitaceae, Malvaceae and Solanaceae), including weeds. It may induce symptoms on its hosts, causing severe yield reduction. The virus is transmitted in a persistent, circulative and non‐propagative manner by the leafhopper species Orosius orientalis and O. albicinctus, which are not regulated. O. orientalis is known to be present in some EU member states. Plants for planting (other than seeds), parts of plants and cut flowers of CpCDV hosts and viruliferous leafhoppers were identified as the most relevant pathways for the entry of CpCDV into the EU. Cultivated and wild hosts of CpCDV are distributed across the EU. Would the pest enter and establish in the EU territory, impact on the production of cultivated hosts is expected. Phytosanitary measures are available to prevent entry and spread of the virus in the EU. CpCDV fulfils the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. [ABSTRACT FROM AUTHOR]

Early detection of new pests can reduce their long-term impacts by enabling more rapid management response. Knowledge of pest establishment risk and background rates of detection (e.g., by the public) can help inform more cost-effective targeting of formal early detection survey programs. Here we quantify county-level locational attributes associated with pest establishment and detection by the public using data for 113 new pest incursions detected in the United States from 2010 through 2018. Aligning with expectations, we find a higher likelihood of new pest establishment in counties with higher human population numbers, nearer to ports (<250 km), and with amenable climate characteristics. Controlling for potential sample selection issues, we find that pests are less likely to be first detected by the public (e.g., homeowners, community members) versus by other sources (e.g., agency surveys, researchers, or agricultural operators) in counties with higher total crop sales values and lower human population number. The negative association between public detection and high agricultural values may reflect greater survey efforts by other sources (e.g., by agency surveillance programs, researchers, and agricultural operators) in high-value agricultural areas. The positive association between public detection and human population size may reflect larger numbers of public detectors (i.e., people) available to encounter the pests. Our models provide spatially explicit estimates of the likelihood of new pest establishment across U.S. counties and of the likelihood that an established pest would first be detected by the public. These estimates can serve as quantitative inputs to decision-support activities for new pest surveillance planning. • New pest introductions associated with human population, port proximity, and climate. • Public detection linked to high human population (where more potential detectors). • Public detection plays relatively greater role in low agricultural value areas. • High human population associated with both pest establishment and public detection.

Abstract The EFSA Panel on Plant Health performed a pest categorisation of Nipaecoccus viridis (Hemiptera: Sternorrhyncha: Pseudococcidae), the spherical scale, for the EU. It is of Asian origin and occurs widely in southern Asia, Africa and tropical Australia. It has been introduced to a few countries in the Americas. In the Mediterranean basin it is found in Algeria, Egypt, Israel, Syria and Turkey, where it is limited to the Marmara region. It has not been reported within the EU. It is not listed in Annex II of Commission Implementing Regulation (EU) 2019/2072. It reproduces sexually, has three generations each year in citrus orchards in South Africa, and all stages can overwinter. First instar nymphs may move to neighbouring plants by crawling or be passively dispersed by wind or hitchhiking on clothing, equipment or animals. It is highly polyphagous, feeding on plants in 115 genera and 46 families. It is an important pest of citrus (Citrus spp.), cotton (Gossypium spp.), mango (Mangifera indica), avocado (Persea americana) and stored potatoes (Solanum tuberosum). It also feeds on a wide range of other fruit (apple Malus domestica, olive Olea europea, pear Pyrus communis and grape Vitis vinifera) and vegetable crops (tomato Solanum lycopersicum), and ornamental plants (roses, Rosa spp.) that are widely grown in the EU. Plants for planting, fruits, vegetables, and cut flowers are the main potential pathways for entry of N. viridis into the EU. Climatic conditions and availability of host plants in southern parts of the EU where there are few days of frost each year would likely allow this species to successfully establish and spread. Reductions in yield and quality of cultivated hosts including avocado, citrus, cotton and mango is anticipated if establishment occurs. Phytosanitary measures are available to reduce the likelihood of entry and spread. N. viridis meets the criteria that are within the remit of EFSA to assess for this species to be regarded as a potential Union quarantine pest.
