Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus X (PVX). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact and availability of control measures of non-EU isolates of PVX has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non-EU isolates of PVX are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. On the basis of their ability to overcome potato resistance genes, PVX isolates can be divided into several pathotypes. PVX isolates that are not able to overcome resistance genes and PVX isolates that are able to overcome the Nb and/or Nx resistance genes are already present in the EU. Isolates able to overcome the Rx resistance gene have only been reported from South America. These Rx breaking isolates could potentially have an additional impact over the current situation in the EU and therefore meet all the criteria to qualify as a potential Union quarantine pest. All other non-EU isolates, should they be introduced, are not expected to have additional impact and therefore do not meet this criterion to qualify as a potential Union quarantine pest.

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non‐EU isolates of potato leafroll virus (PLRV). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact and availability of control measures of non‐EU isolates of PLRV has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non‐EU isolates of PLRV are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non‐quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. This categorisation was performed considering two groups of PLRV isolates: those associated with the tomato yellow top disease (PLRV‐TYTV), not reported from the EU, and all other isolates (hereafter referred to as PLRV), with a worldwide distribution. Isolates of PLRV‐TYTV could potentially have an additional impact over the current situation in the EU and therefore meet all the criteria to qualify as a potential Union quarantine pest. All other non‐EU PLRV isolates, should they be introduced, are not expected to have additional impact and therefore do not meet this criterion to qualify as a potential Union quarantine pest.

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus Y (PVY). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways and potential additional impact of non-EU isolates of PVY, has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non-EU isolates of PVY are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. Populations of PVY can be subdivided into several strains and groups of isolates: strain C (PVY-C), strain N (PVY-N), strain O (PVY-O) and a wide range of recombinant isolates (PVYrecombinants) which have a worldwide distribution (including the EU). Two groups of isolates, i.e. the Brazilian (PVY-Br) and Chilean (PVY-Ch) isolates, are considered absent from the EU. Non-EU isolates of PVY-C, PVY-N, PVY-O and PVY-recombinants identified so far are not expected to have an additional impact in the EU compared to the PVY isolates already present and, therefore, do not meet the corresponding criterion to qualify as a potential Union quarantine pest. The Panel is unable to conclude on the potential additional impact of isolates of PVY-Br and PVY-Ch in the EU territory, but these isolates meet all the other criteria to qualify as potential Union quarantine pests.

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus V (PVV). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact and availability of control measures of non-EU isolates of PVV has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non-EU isolates of PVV are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. This categorisation was performed considering two lineages, PVV-I (present in and outside the EU) and PVV-II (not reported in the EU), and isolate PVV-PA4 (unknown distribution). Non-EU isolates of PVV-I and PVV-PA4 do not meet one of the criteria evaluated by EFSA to be regarded as a potential Union quarantine pest, since they are not expected to have an additional impact in the EU. With the exception of the criterion regarding the potential consequences in the EU territory, for which the Panel is unable to conclude, non-EU isolates of PVV-II meet all the other criteria to qualify as a potential Union quarantine pest.

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus A (PVA). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact over the current situation and availability of control measures of non-EU isolates of PVA has been evaluated with regard to the criteria to qualify as potential Union quarantine pest. Because non-EU isolates of PVA are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. This categorisation was performed considering two groups of isolates: those reported in Solanum betaceum (PVA-TamMV, not reported from the EU) and all other isolates (hereafter referred to as PVA, worldwide distribution). Non-EU isolates of PVA and of PVA-TamMV do not meet one of the criteria evaluated by EFSA to be regarded as a potential Union quarantine pest, since they are not expected to have an additional impact in the EU.

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus S (PVS). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact compared to the current situation in the EU, and availability of control measures of non-EU isolates of PVS has been evaluated with regard to the criteria to qualify as potential Union quarantine pest. Because non-EU isolates of PVS are absent from the EU, they do not meet one of the requirements to be regulated as an RNQP (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. Populations of PVS can be subdivided into two strains: the ordinary strain (PVS-O) with a worldwide distribution (including the EU), and the Andean strain (PVS-A) which is absent from the EU or considered to have at most a limited distribution in the EU. Two additional divergent isolates (PVS-A/PVS-O recombinants and PVS-arracacha) have also been categorised. Non-EU isolates of PVS-A are expected to have an additional impact as compared to the PVS isolates currently present in the EU, and therefore meet all the criteria to qualify as potential Union quarantine pests; the magnitude of the additional impact is, however, unknown. Non-EU isolates of PVS-A/PVS-O recombinants and of PVS-arracacha also meet these criteria, with the exception of the criterion regarding the potential additional consequences in the EU territory for which the Panel was unable to conclude. Non-EU PVS-O isolates are not expected to have an additional impact in the EU as compared to EU isolates and therefore do not meet the corresponding criterion. [ABSTRACT FROM AUTHOR]

Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of non-EU isolates of potato virus M (PVM). The information currently available on geographical distribution, biology, epidemiology, potential entry pathways, potential additional impact compared to the current situation in the EU and availability of control measures of non-EU isolates of PVM has been evaluated with regard to the criteria to qualify as a potential Union quarantine pest. Because non-EU isolates of PVM are absent from the EU, they do not meet one of the requirements to be regulated as a regulated non-quarantine pest (RNQP) (presence in the EU); as a consequence, the Panel decided not to evaluate the other RNQP criteria for these isolates. Populations of PVM can be subdivided into two strains: the ordinary strain (PVM-O) is present in the EU, while the divergent strain (PVM-D) is absent from the EU or considered to have at most a limited distribution in the EU. Non-EU isolates of PVM-O are not expected to have an additional impact in the EU compared to EU isolates and therefore do not meet the corresponding criterion to qualify as a potential Union quarantine pest. The Panel is unable to conclude on the potential impact of non-EU PVM-D isolates in the EU territory, but PVM-D isolates meet all the other criteria to qualify as a potential Union quarantine pest.

Abstract The Panel on Plant Health performed a pest categorisation of non‐EU Acleris spp. Acleris is a well‐defined insect genus in the family Tortricidae (Insecta: Lepidoptera). Species can be identified using taxonomic keys based on adult morphology and genitalia. The genus includes 261 species attacking conifers and non‐conifer plants in many areas in the world, among which 40 species are present in the EU. The non‐EU species are collectively listed in Annex IAI of Council Directive 2000/29/EC as Acleris spp. (non‐European). Some species are important defoliators in North America, mainly on conifers but also on several broadleaf trees. Females lay eggs on the leaves or on the bark. The larvae bind together with silk the leaves upon which they feed. Pupation occurs in leaves attached with silk or in the soil. Some species are univoltine; others are bivoltine or multivoltine. Flight capacity is not documented, but outbreak expansion suggests that the adults can probably fly long distances. The main pathways for entry are host plants for planting with or without soil, cut branches, fruits of host plants (including cones), round wood with bark and bark. The presence of host plants and suitable EU climate would allow the establishment of the known non‐EU harmful species. In the literature, nine non‐EU Acleris species are reported as pests on various host plants, namely A. gloverana, A. variana, A. minuta, A. nishidai, A. issikii, A. semipurpurana, A. robinsoniana, A. senescens and A. nivisellana. These non‐EU Acleris spp. satisfy all the criteria to be considered as Union quarantine pests. Concerning the other 212 non‐EU Acleris species, there is scarce information on host plants, pests status and climatic suitability. Measures are in place to prevent the introduction of non‐EU Acleris spp. through the pathways described in the document. As non‐EU Acleris spp. are not present in the EU and plants for planting are not the major pathway for spread, non‐EU Acleris spp. do not meet the criteria to be considered as regulated non‐quarantine pests.

Abstract The Panel on Plant Health performed a listing of non‐EU viruses and viroids (reported hereinafter as viruses) of Cydonia Mill., Fragaria L., Malus Mill., Prunus L., Pyrus L., Ribes L., Rubus L. and Vitis L. A systematic literature review identified 197 viruses infecting one or more of the host genera under consideration. Viruses were allocated into three categories (i) 86 non‐EU viruses, known to occur only outside the EU or having only limited presence in the EU (i.e. reported in only one or few Member States (MSs), known to have restricted distribution, outbreaks), (ii) 97 viruses excluded at this stage from further categorisation efforts because they have significant presence in the EU (i.e. only reported so far from the EU or known to occur or be widespread in some MSs or frequently reported in the EU), (iii) 14 viruses with undetermined standing for which available information did not readily allow to allocate to one or the other of the two above groups. Comments provided by MSs during consultation phases were integrated in the opinion. The main knowledge gaps and uncertainties of this listing concern (i) the geographic distribution and prevalence of the viruses analysed, in particular when they were recently described; (ii) the taxonomy and biological status of a number of poorly characterised viruses; (iii) the host status of particular plant genera in relation to some viruses. The viruses considered as non‐EU and those with undetermined standing will be categorised in the next steps to answer a specific mandate from the Commission to develop pest categorisations for non‐EU viruses. This list does not imply a prejudice on future needs for a pest categorisation for other viruses which are excluded from the current categorisation efforts.

Abstract Following a request from the EU Commission, the Panel on Plant Health performed a pest categorisation of 17 viruses and viroids, herein called viruses, of Cydonia Mill., Malus Mill. and Pyrus L. determined as being either non‐EU or of undetermined standing in a previous EFSA opinion. These viruses belong to different genera and are heterogeneous in their biology. They can be detected by available methods and are efficiently transmitted by vegetative propagation techniques, with plants for planting representing a major long‐distance spread mechanism and, potentially, a major entry pathway. Depending on the viruses, additional pathway(s) can also be seed, pollen and/or vector transmission. Most of the viruses categorised here are known to infect only one of few related plant genera, but some of them have a wider host range, thus extending the possible entry pathways. Three viruses (apple necrotic mosaic virus, cherry rasp leaf virus, temperate fruit decay‐associated virus) and one viroid (apple fruit crinkle viroid) satisfy all the criteria to be considered as Union quarantine pests. Five viruses (apple green crinkle‐associated virus, blackberry chlorotic ringspot virus, eggplant mottled crinkle virus, tobacco ringspot virus and tomato ringspot virus) and one viroid (apple scar skin viroid), satisfy the criteria to be considered as Union quarantine pests with the possible exception of being absent from the EU territory or having a restricted presence and being under official control. The remaining six viruses (apple geminivirus, apple latent spherical virus, apple‐associated luteovirus, Pyrus pyrifolia cryptic virus, Pyrus pyrifolia partitivirus 2 and Tulare apple mosaic virus) and one viroid (apple hammerhead viroid) were not found to satisfy one or more of these criteria. The Panel highlights that for several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly linked to the absence of data on biology and distribution. Since this opinion addresses specifically the non‐EU viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as a potential Union regulated non‐quarantine pests.

Abstract Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Fragaria L. determined as being either non‐EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of strawberry latent virus and strawberry latent C virus for which very limited information exists, the pest categorisation was completed for 12 viruses having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative propagation techniques, with plants for planting representing the major pathway for long‐distance dispersal and thus considered as the major pathway for entry. Depending on the virus, additional pathway(s) can also be Fragaria seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Strawberry chlorotic fleck‐associated virus, strawberry leaf curl virus, strawberry necrotic shock virus, strawberry pallidosis‐associated virus, strawberry vein banding virus (SVBV) and tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). For SVBV, the Panel considered that following its entry and establishment into the EU territory, an impact of uncertain magnitude is expected mainly because a synergistic effect may occur in strawberry in case of mixed infections with viruses already present in the EU. Strawberry crinivirus 3, strawberry crinivirus 4 and strawberry polerovirus 1 meet all criteria for being considered as potential Union QPs, except for the impact in the EU territory, on which the Panel was unable to conclude. Fragaria chiloensis cryptic virus, Fragaria chiloensis latent virus and strawberry pseudo mild yellow edge virus do not meet the criterion of having potential negative impact in the EU. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically the non‐EU viruses, in general, these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non‐quarantine pests.

Abstract Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Prunus L. determined as being either non‐EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of Ilarvirus S1 and Ilarvirus S2, for which very limited information exists, the pest categorisation was completed for 26 viruses and 1 viroid having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative plant propagation techniques, with plants for planting representing the major pathway for long‐distance dispersal and thus considered as the major pathway for entry. Depending on the virus, additional pathway(s) can also be Prunus seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Apple scar skin viroid, American plum line pattern virus, cherry mottle leaf virus, cherry rasp leaf virus, cherry rosette virus, cherry rusty mottle‐associated virus, cherry twisted leaf‐associated virus, peach enation virus, peach mosaic virus, peach rosette mosaic virus, tobacco ringspot virus and tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). With the exception of impact in the EU territory, on which the Panel was unable to conclude, apricot vein clearing virus, Asian prunus virus 1, Asian prunus virus 2, Asian prunus virus 3, Caucasus prunus virus, cherry virus B, Mume virus A, nectarine stem pitting‐associated virus, nectarine virus M, peach chlorotic mottle virus, peach leaf pitting‐associated virus, peach virus D, prunus virus F and prunus virus T satisfy all the other criteria to be considered as potential Union QPs. Prunus geminivirus A does not meet the criterion of having negative impact in the EU. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically the non‐EU viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as potential Union regulated non‐quarantine pests.

Abstract Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses and viroids of Vitis L. determined as being either non‐EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to different genera and are heterogeneous in their biology. With the exclusion of grapevine virus 101‐14.N.23.9.1/South Africa/2009 for which very limited information exists, the pest categorisation was completed for 30 viruses or viroids having acknowledged identities and available detection methods. All these viruses are efficiently transmitted by vegetative propagation techniques, with plants for planting representing the major pathway for long‐distance dispersal and thus considered as the major pathway for potential entry. Depending on the virus, additional pathway(s) can also be seeds, pollen and/or vector(s). Most of the viruses categorised here are known to infect only one or few plant genera, but some of them have a wide host range, thus extending the possible entry pathways. Grapevine yellow speckle viroid 2, blueberry leaf mottle virus, grapevine Ajinashika virus, grapevine Anatolian ringspot virus, grapevine berry inner necrosis virus, grapevine deformation virus, grapevine fabavirus, grapevine red blotch virus, grapevine stunt virus, grapevine Tunisian ringspot virus, grapevine vein‐clearing virus, temperate fruit decay‐associated virus, peach rosette mosaic virus, tobacco ringspot virus, tomato ringspot virus meet all the criteria evaluated by EFSA to qualify as potential Union quarantine pests (QPs). With the exception of impact for the EU territory, on which the Panel was unable to conclude, blackberry virus S, grapevine geminivirus A, grapevine leafroll‐associated virus 7, grapevine leafroll‐associated virus 13, grapevine satellite virus, grapevine virus E, grapevine virus I, grapevine virus J, grapevine virus S, summer grape enamovirus, summer grape latent virus satisfy all the other criteria to be considered as potential Union QPs. Australian grapevine viroid, grapevine cryptic virus 1, grapevine endophyte endornavirus and wild vitis virus 1 do not meet all the criteria evaluated by EFSA to be regarded as potential Union QPs because they are not known to cause an impact on Vitis. For several viruses, especially those recently discovered, the categorisation is associated with high uncertainties mainly because of the absence of data on their biology, distribution and impact. Since this opinion addresses specifically non‐EU viruses, in general these viruses do not meet the criteria assessed by EFSA to qualify as a potential Union regulated non‐quarantine pests.

Abstract The EFSA Panel on Plant Health (PLHP) performed a pest categorisation of Spodoptera litura (Lepidoptera: Noctuidae) for the EU. S. litura is widely distributed across South and East Asia and Oceania. It is established in tropical and subtropical regions where there are no, or few, frost days each year. It can extend its range into cooler temperate regions during summer months. S. litura is highly polyphagous feeding on hosts within at least 40 botanical families, including economically important crops within Brassicaceae, Cucurbitaceae, Fabaceae, Malvaceae, Poaceae and Solanaceae. Larvae are primarily leaf feeders and can cause complete defoliation. At high population densities almost all plant parts are eaten. S. litura is a serious pest in the Asia‐Pacific region where it causes losses to many economically important cultivated field crops and crops such as eggplants, sweet peppers and tomatoes in protected cultivation. As a species that appears limited by winter temperatures, only a small area of the EU provides climatic conditions where establishment outdoors may be possible although cultivated and wild hosts are distributed across the EU. S. litura has been intercepted in the EU many times on ornamentals and leafy vegetables. Outbreaks have occurred in EU glasshouses and have been eradicated. Phytosanitary measures are available to inhibit entry. S. litura satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest. S. litura does not meet the criteria of occurring in the EU, and plants for planting being the principal means of spread for it to be regarded as a potential Union regulated non‐quarantine pest.

Abstract The Panel on Plant Health performed a group pest categorisation of non‐EU Cicadomorpha vectors of Xylella spp. known to be associated with plant diseases. Although all the insects considered in this categorisation are proven vectors of Xylella spp., additional vectors within the order Hemiptera most probably exist but have not been associated with any Xylella spp. disease yet. Currently, the group consists of 50 taxa (49 at species level and one at genus level) from the families Aphrophoridae, Cicadellidae and Membracidae (Arthropoda: Hemiptera: Cicadomorpha) for which reliable identification methods exist. Members of the group can be found in the Americas, Asia, Africa and Oceania. Only one of them, Homalodisca vitripennis is considered invasive. Species in the group are mostly polyphagous; many are known to feed on several plant families. Hosts can include broadleaf trees, herbaceous plants and grasses. Breeding takes place on herbaceous hosts and eggs are inserted into plant tissues. Nymphs emerge to feed on sap of the natal host. Adults move from breeding hosts to food hosts and can spread Xylella spp. causing a variety of diseases. Three of the species are listed in Annex IAI of Council Directive 2000/29/EC as examples of Cicadellidae (non‐EU) known to be vector of Pierce's disease (caused by Xylella fastidiosa). Plants for planting, cut branches, flowers and fruit are potential pathways for entry into the EU. However, there are no records of EU interceptions of any members of the group. EU biotic and abiotic conditions are conducive for establishment and spread of these insects. Were members of the group to establish and spread, impact on several cultivated species (e.g. grapevine, citrus, Prunus spp.) and ornamentals (e.g. Polygala myrtifolia) could be expected as these insect species are efficient vectors of Xylella spp. Considering the criteria within the remit of EFSA to assess their regulatory plant health status, the group of non‐EU Cicadomorpha vectors of Xylella spp. meets all the criteria assessed by EFSA for consideration as potential Union quarantine pests. The group does not meet all the criteria assessed by EFSA for consideration as regulated non‐quarantine pests, as members of the group are not present in the EU.

Abstract The Panel on Plant Health performed a pest categorisation of non‐EU Choristoneura spp. Choristoneura is a well‐defined insect genus in the family Tortricidae (Insecta: Lepidoptera). Species can be identified using taxonomic keys and molecular methods. The genus includes 52 species and subspecies colonising conifers and non‐conifer trees in many areas in the world, among which five species are present in the EU. The non‐EU species are listed in Annex IAI of Council Directive 2000/29/EC as Choristoneura spp. (non‐European). Some Choristoneura species are important defoliators in North America, mainly on conifers but also on several broadleaf tree species and on non‐forest crops. Females lay eggs in batches on the needles or the leaves, and overwintering occurs at the larval stage in a silken hibernaculum. Most species are univoltine, some are bivoltine and at least one subspecies has a 2‐year life cycle. Pupation occurs on the twigs of conifers or in folded leaves of broadleaf trees. The adults are strong flyers, and the larvae can disperse by ballooning. The main pathways for entry are plants for planting, cut branches, fruits of host plants (including cones), round wood with bark and bark. Suitable host plants and climate would allow the establishment in the EU of the known, North American harmful species. Non‐EU Choristoneura spp. satisfy all the criteria to be considered as Union quarantine pests. Measures are in place to prevent the introduction of non‐EU Choristoneura spp. through the pathways described above. As non‐EU Choristoneura spp. are not present in the EU and plants for planting are not the major pathway for spread, non‐EU Choristoneura spp. do not meet the criteria to be considered as regulated non‐quarantine pests.

Abstract The Panel on Plant Health performed a pest categorisation of species in the family Margarodidae (Hemiptera: Coccomorpha; Coccoidea). Of 107 species of Margarodidae, 97 are not known to occur in the EU. Margarodids are cosmopolitan soil‐dwelling species. The nymphs suck on the roots of host plants, while the adults have no mouthparts and do not feed. Some species are serious destructive pests of grape vines, sugar cane, oil palms, cotton or turf grass. The import of soil or rooted plants for planting with soil are potential pathways for entry. Measures are available to inhibit entry. Non‐European species in the genus Margarodes are regulated on Vitis plants for planting by Council Directive 2000/29/EC (Annex IIAI). Non‐EU Margarodidae species were categorised into three groups. The first group includes 11 species reported as pests of crop plants that satisfy all of the criteria that are within the remit of EFSA to assess, to be regarded as Union quarantine pests. The second group includes 10 species that are not reported to cause economic damage to plants although they do feed on plants that are grown in the EU; these species do not satisfy all the criteria to be regarded as Union quarantine pests. Uncertainty exists whether species in this group could cause damage if they were introduced into the EU. The third group includes 76 species that appear restricted to climate and soil types that do not occur in the EU, feed on hosts that have limited significance in the EU, or are little studied due to their lack of impact. There is no evidence that these species satisfy the criteria to be regarded as Union quarantine pests in the EU. For completeness, the 10 species of Margarodidae that are known to occur in the EU are named in the opinion.

Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of Clavibacter sepedonicus, a well‐defined and distinguishable bacterial plant pathogen of the family Microbacteriaceae. C. sepedonicus causes bacterial ring rot of potato and is reported from North America, Asia and Europe. The bacterium is mostly tuber transmitted, but it can also enter host plants through wounds or via contaminated equipment. C. sepedonicus is regulated in Council Directive 2000/29/EC (Annex IAII, as Clavibacter michiganensis subsp. sepedonicus) as a harmful organism whose introduction into the EU is banned. In addition, Council Directive 1993/85/EEC concerns the measures to be taken within EU Member States (MS) against C. sepedonicus to (a) detect it and determine its distribution, (b) prevent its occurrence and spread, and (c) control it with the aim of eradication. The pest is present in several EU MS, but in all cases with a restricted distribution and under official control. C. sepedonicus could enter the EU and spread primarily via host plants for planting (i.e. potato tubers). The pest could establish in the EU, as the main host (potato) is commonly grown and climatic conditions are favourable. Direct potato losses following infection by C. sepedonicus can be substantial and are due to the destruction of the vascular tissue, wilting of the plant and rotting of the tubers. Infected hosts can remain asymptomatic. The main knowledge gaps are the geographic distribution of the pest and the host range. The criteria assessed by the Panel for consideration of C. sepedonicus as a potential quarantine pest are met, while, for regulated non‐quarantine pests, the criterion on the widespread presence in the EU is not met.

Abstract The Panel on Plant Health performed a pest categorisation of Arrhenodes minutus, a well‐defined wood‐boring insect species in the family Brentidae (Insecta: Coleoptera). It can be identified using taxonomic keys. A. minutus is only present in southern Canada and eastern USA down to Florida. The main host plants of A. minutus are species of the genera Quercus, Ulmus, Fagus and Populus. The pest larvae bore galleries in the wood, causing structural damage to the timber. The pest is also a vector of the quarantine pest Breziella (Ceratocystis) fagacearum. A. minutus most often lays its eggs in wounded parts of the trees where sap is oozing. The female bores minute holes with her snout and deposits one egg in each of them. The larvae bore a straight gallery against the grain. When the gallery nearly reaches the other side of the bole, it makes a sharp U‐turn towards the point of origin. These galleries cause structural damage to the timber. The life cycle lasts generally 3 years, but some individuals develop in 2 years and a few require 4 years. The main pathways are wood and possibly plants for planting. Specific phytosanitary requirements exist for Quercus and Populus only, while Ulmus is regulated in relation to other pests. Establishment would be favoured by the wide distribution of host trees in the EU territory and by climatic conditions locally comparable to those of the pest's native range. A. minutus meets all the criteria assessed by EFSA for consideration as potential Union quarantine pest. The criteria for considering it as a potential Union regulated non‐quarantine pest are not met since the species is absent from the EU.

Abstract The EFSA Panel on Plant Health (PLH) performed a pest categorisation of Thrips palmi (Thysanoptera: Thripidae), for the EU. T. palmi is listed in Annex IAI of 2000/29 EC. Using molecular methods, cryptic speciation has been shown although no new species from the group have been formally described. Here, we consider T. palmi sensu lato as a defined species native to southern Asia, which has spread to tropical and subtropical countries in Asia, the Pacific, North, Central and South America, Africa and Australia. T. palmi has been reported from many different hosts in 20 botanical families; Cucurbitaceae, Solanaceae and Orchidaceae are of primary importance. T. palmi has been intercepted many times on plants from these families. Wild and cultivated hosts are widespread in the EU. However, as a subtropical and tropical species, only a small area of the EU provides climatic conditions where establishment may be possible outdoors. Several host plants are cultivated in glasshouses where conditions may be more favourable for establishment in year‐round crops. There have been past outbreaks of T. palmi in EU glasshouses and outdoors in Portugal. T. palmi causes feeding and oviposition damage and populations in Asia are competent vectors of tospoviruses. Impacts could occur on many hosts, especially Cucurbitaceae, Solanaceae and ornamental plants particularly in glasshouses. Phytosanitary measures aim to prevent the entry of T. palmi specifically on cut flowers of Orchidaceae and fruits of Momordica and Solanum melongena. The species meets all the criteria assessed by the PLH Panel to satisfy the definition of a Union quarantine pest, while it does not satisfy all the criteria for it to be regarded as a Union regulated non‐quarantine pest (RNQP).

Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of the Ralstonia solanacearum species complex (RSSC), a distinguishable cosmopolitan group of bacterial plant pathogens (including R. solanacearum, Ralstonia pseudosolanacearum and two subspecies of Ralstonia syzygii) of the family Burkholderiaceae. The RSSC causes bacterial wilt in solanaceous crops, such as potato, tomato and pepper, but can also cause wilts in other important food crops such as fruit banana, plantain banana and cassava. The pest survives in the soil, and a number of weed species can also be infected by the pest, often asymptomatically. The RSSC is regulated in Council Directive 2000/29/EC (Annex IAII) (indicated by its former name R. solanacearum, as delimited by Yabuuchi et al.) as a harmful organism whose introduction into the EU is banned. In addition, Council Directive 1998/57/EC (amended by Commission Directive 2006/63/CE) concerns the measures to be taken within EU Member States (MS) against the RSSC to (a) detect it and determine its distribution, (b) prevent its occurrence and spread, and (c) control it with the aim of eradication. The pest is present in several EU MS, but in all cases with a restricted distribution and under official control. New phylotypes of the RSSC could enter the EU primarily via host plants for planting (including seed tubers). The pest could establish in the EU, as climatic conditions are favourable, hosts are common and the pathogen has high adaptability. Spread is mainly via plants for planting. Substantial crop losses in the EU would occur in the presence of RSSC epidemics. The RSSC is regarded as one of the world's most important phytopathogenic bacteria due to its broad geographical distribution, large host range, aggressiveness, genetic diversity and long persistence in soil and water. The list of hosts and commodities for which the pest is regulated is incomplete due to the high diversity of hosts and the lack of knowledge of the complete host range. Moreover, the comparative epidemiology of the different pathogen species has not yet been studied. The criteria assessed by the Panel for consideration of the RSSC as potential quarantine pest are met, while, for regulated non‐quarantine pests, the criterion on the widespread presence in the EU is not met.

Abstract The Panel on Plant Health performed a pest categorisation of Pseudopityophthorus minutissimus and Pseudopityophthorus pruinosus, two well‐defined insect species in the family Curculionidae, subfamily Scolytinae (Insecta: Coleoptera). They can be identified using taxonomic keys. P. minutissimus is present in parts of Canada and the USA, and P. pruinosus is present in parts of the USA, Guatemala, Honduras and Mexico. The main host plants of the two species are Quercus spp., but they also attack several other genera. The two species mostly colonise weakened or dead branches but can also attack the stems. They are mostly secondary pests but they vector the oak wilt fungus, Bretziella fagacearum, which causes heavy damage in American Quercus spp. populations. The fungus is mainly transmitted by the young adults during their maturation feeding on twigs, leaf petioles and young acorn stems. The beetles are polygamous and have two generations per year in most of their range. The main pathways are wood, bark, plants for planting, cut branches, chips and wood waste. These pathways are fully or partly regulated for the genera Quercus, Castanea and Prunus. However, the pathways are not regulated for the following genera: Carpinus, Fagus, Hamamelis, Alnus. P. minutissimus and P. pruinosus meet all the criteria assessed by EFSA for consideration as potential Union quarantine pest. The criteria for considering P. minutissimus and P. pruinosus as potential Union regulated non‐quarantine pests are not met since neither species are known to be present in the EU.

The EFSA Panel on Plant Health performed a pest categorisation of Malacosoma parallela (Staudinger) (Lepidoptera: Lasiocampidae) for the territory of the European Union, following commodity risk assessments of Berberis thunbergii, Malus domestica , Prunus persica and P. dulcis plants for planting from Türkiye, in which M. parallela came to attention as of possible concern. M. parallela is commonly known as the mountain ring silk moth and is a polyphagous leaf-eating pest in west-central Asia, primarily feeding on deciduous trees and shrubs, and known to cause serious damage to Malus, Prunus, and Quercus species. It is found at a range of altitudes from 130 m to 3000 m although most common above 1000 m. It is a univoltine species. Eggs are laid in masses on twigs and branches in the summer and larvae hatch the following spring to feed on buds and fresh leaves. Host plants can be completely defoliated. Plants for planting and cut branches provide pathways for entry, especially if infested with egg masses. Host availability and climate suitability suggest that parts of the EU would be suitable for establishment. Adults can fly and the pest could spread naturally within the EU although adults only live for a few days. Faster and more extensive spread is therefore more likely via egg masses moved on plants for planting. The introduction of M. parallela into the EU could lead to outbreaks causing damage to deciduous trees and shrubs in forests and orchards. Phytosanitary measures are available to inhibit the entry and spread of this species. M. parallela satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2024 European Food Safety Authority.

Following the EFSA commodity risk assessment of Malus domestica plants imported from Türkiye into the EU, the EFSA Panel on Plant Health performed a pest categorisation of Pratylenchus loosi (Nematoda: Pratylenchidae) for the EU. Pratylenchus loosi belongs to the order Rhabditida, subfamily Pratylenchidae. This nematode is not known to be present in the EU. The species is not included in the EU Commission Implementing Regulation 2019/2072. The pest occurs primarily in tropical, subtropical and warm temperate areas. It is widely distributed in Asian countries, with tea plants ( Camellia sinensis ) as the main host. The pest was reported from more than 60 plant species, but reports from hosts other than C. sinensis , e.g. citrus ( Citrus spp.) and banana ( Musa spp.), are associated with high uncertainty due to doubtful pest identification. Morphological and molecular methods are available for the identification of the pest. Pathways of entry are host plants for planting except seeds, as well as soil attached to plants for planting, machinery or footwear. Soil import to the EU is prohibited from third countries. The climatic preferences of P. loosi are compatible with the microclimatic conditions occurring in the areas of the EU where tea is grown outside. The impact of the nematode is primarily known for Asian countries, where it is a devastating pathogen on tea plants, but there is a key uncertainty on impacts on hosts other than tea. Considering the strong pathogenicity of the pest, its establishment in tea producing areas would have negative consequences for tea producers. Therefore, the Panel concludes that P. loosi satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2024 European Food Safety Authority.

Following an EFSA commodity risk assessment of bonsai plants ( Pinus parviflora grafted on Pinus thunbergii ) imported from China, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis microspora, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen was reported on a wide range of monocotyledonous, dicotyledonous and gymnosperms, either cultivated or wild plant species, causing various symptoms such as leaf spot, leaf blight, scabby canker, fruit spot, pre- and post-harvest fruit rot and root rot. In addition, the fungus was reported as an endophyte on a wide range of asymptomatic plant species. This pest categorisation focuses on the hosts that are relevant for the EU and for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequencing analyses. Pestalotiopsis microspora was reported in Africa, North, Central and South America, Asia and Oceania. In the EU, it was reported in the Netherlands. There is a key uncertainty on the geographical distribution of P. microspora worldwide and in the EU, because of the endophytic nature of the fungus, the lack of surveys, and because in the past, when molecular tools were not fully developed, the pathogen might have been misidentified as other Pestalotiopsis species or other members of the Pestalodiopsidaceae family based on morphology and pathogenicity tests. Pestalotiopsis microspora is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting, fresh fruits, bark and wood of host plants as well as soil and other growing media associated with plant debris are the main pathways for the entry of the pathogen into the EU. Host availability and climate suitability in parts of the EU are favourable for the establishment and spread of the pathogen. The introduction and spread of the pathogen into the EU are expected to have an economic and environmental impact where susceptible hosts are grown. Phytosanitary measures are available to prevent the introduction and spread of the pathogen into the EU. Unless the restricted distribution in the EU is disproven, Pestalotiopsis microspora satisfies all the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2023 European Food Safety Authority.

Following the commodity risk assessments of bonsai plants from China consisting of Pinus parviflora grafted on P. thunbergii performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis disseminata, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen has been reported on herbaceous, woody and ornamental plants causing symptoms such as leaf blight, shoot blight, seedling blight, pod canker, pre- and post-harvest fruit rot, and gummosis. Moreover, the fungus was reported as an endophyte on a wide range of asymptomatic hosts. The pathogen is present in Africa, North and South America, Asia, Europe and Oceania. It has been reported from the EU, with a restricted distribution (Portugal). There is a key uncertainty on the geographical distribution of P. disseminata in the EU and worldwide, because of the endophytic nature of the fungus, the lack of surveys and since the pathogen might have been misidentified based only on morphology and pathogenicity tests. The pathogen is not included in Commission Implementing Regulation (EU) 2019/2072. This pest categorisation focuses on those hosts that are relevant for the EU and 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, bark and wood of host plants as well as soil and other plant growing media are the main pathways for the entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the establishment of the pathogen. Despite the low aggressiveness observed in most reported hosts, and the fact that P. disseminata may colonise plants as an endophyte, its introduction and spread in the EU may have an economic and environmental impact (with a key uncertainty) where susceptible hosts are grown. Phytosanitary measures are available to prevent the introduction and spread of the pathogen. The Panel cannot conclude on whether P. disseminata satisfies all the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest, because of the key uncertainties on the restricted distribution in the EU and the magnitude of the impact., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2023 European Food Safety Authority.

The EFSA Panel on Plant Health performed a pest categorisation of Mimela testaceipes (Coleoptera: Scarabaeidae), the striated chafer, for the EU, following a commodity risk assessment of dwarfed Pinus parviflora grafted onto P. thunbergii from China in which M. testaceipes was identified as a pest of possible concern to the EU. M. testaceipes occurs in Japan, northeast China, Far East Russia, South Korea and very likely North Korea. Adults are recognised pests feeding on and damaging the needles of Japanese cedar ( Cryptomeria japonica ), Japanese cypress ( Chamaecyparis obtusa ) and Japanese larch ( Larix leptolepis ) which are important forestry trees where the pest currently occurs. It has adapted to feed on the needles of Pinus species introduced into its native area, such as P. taeda, which is native to southeastern USA although M. testaceipes is not regarded as a significant pest of pines. Larvae are reported to cause root damage to grasses, as well as conifers. Eggs are usually laid in grassy soils by females that develop on conifer species. Larvae develop in the soil feeding on the roots of grasses or conifer hosts. Larvae overwinter in the soil and take 2 or 3 years to develop. In principle soil, host plants for planting and cut branches with foliage could provide pathways into the EU. However, prohibitions on the import of soil and hosts such as Chamaecyparis , Larix and Pinus regulate such pathways into the EU. Nevertheless, certain dwarfed Pinus spp. from Japan are provided with a derogation for entry into the EU. In addition, the host C. japonica is unregulated and could also provide a pathway. Hosts occur in the EU in climate zones that match those where M. testaceipes occurs in Asia. If M. testaceipes were to enter the EU, conditions in central and northern EU are conducive to establishment. Following establishment, impacts on Japanese cedar, Japanese cypress and Japanese larch would be expected; it is possible that M. testaceipes could adapt to feed on Pinus and Larix species growing in Europe. M. testaceipes satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2023 European Food Safety Authority.

The EFSA Panel on Plant Health performed a pest categorisation of Lepidosaphes pineti Borchsenius the pine oyster scale, Lepidosaphes pini (Maskell) the Oriental pine scale and Lepidosaphes piniphila Borchsenius (Hemiptera: Diaspididae) for the EU, following a commodity risk assessment of dwarfed Pinus parviflora grafted onto P. thunbergii from China in which the three Lepidosaphes species were identified as pests of possible concern to the EU. All three species are native to Asia. L. pineti is only known from China; L. piniphila occurs in China, Japan and Malaysia; and L. pini is present in China, Japan, South Korea, Taiwan, and has been introduced to the USA. All three species feed primarily on Pinus spp., including several important forestry and ornamental trees, and L. pineti and L. pini have adapted to feed on North American species of pine. L. pineti also feeds on Torreya grandis ; L. pini on Abies sp., Cunninghamia lanceolata , Cycas spp., Podocarpus spp., Taxus sp. and Torreya sp.; and L. piniphila on Podocarpus spp. and T. grandis . All developmental stages occur on the foliage. Host plants for planting and cut branches with foliage could provide pathways into the EU. However, prohibitions on the import of Pinus close the main pathway. Certain dwarfed Pinus spp. from Japan are provided with a derogation for entry into the EU. The main hosts ( Pinus spp.) occur throughout the EU in climate zones that match those where the three Lepidosaphes species occur in Asia. If any of the three Lepidosaphes species were to enter the EU, conditions in most of the EU are conducive to establishment. Following establishment, impacts on pines by L. pineti and L. pini would be expected. There are no published reports of L. piniphila causing damage to pine. L. pineti and L. pini satisfy the criteria that are within the remit of EFSA to assess for them to be regarded as potential Union quarantine pests. L. piniphila does not satisfy the criteria, as there is no evidence that it is harmful; however, there is a key uncertainty regarding whether it is synonymous with a closely related species, L. pitysophila , which is recorded as a pest of pine in China., Competing Interests: If you wish to access the declaration of interests of any expert contributing to an EFSA scientific assessment, please contact interestmanagement@efsa.europa.eu., (© 2023 European Food Safety Authority.

The EFSA Panel on Plant Health performed a pest categorisation of the citrus root weevil Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) for the European Union (EU) following the commodity risk assessment of Ligustrum delavayanum topiary grafted on L. japonicum plants from the UK in which D. abbreviatus was identified as a relevant non-regulated EU pest which could potentially enter the EU. This species is native to the Caribbean and was introduced to the continental USA in 1964, to Gran Canaria (Spain) in 2014 and to Madeira Island (Portugal) in 2018. It is a polyphagous insect, associated with more than 270 species in 60 plant families. Female D. abbreviatus can lay up to 5,000 eggs in clusters within leaves folded and glued together. Neonate larvae drop off the leaves onto the ground and enter the soil, where they feed on roots for several months. The mature larvae pupate in the soil. After emergence, adults usually stay on the first host plant they encounter and can move long distances on nursery stock. D. abbreviatus is not a regulated pest in the EU. It could enter and spread within the EU via the import and movement of host plants for planting, cut flowers and soil. Some host plants for planting (e.g. Vitis spp., Citrus spp.), and soil are prohibited from entering the EU from countries where this weevil is known to occur. The import of other host plants for planting and cut flowers is subject to phytosanitary certificate and that of soil attached to machinery is regulated. Host availability and climate suitability suggest that the southernmost coastal areas of southern EU MSs would be suitable for establishment of D. abbreviatus . Temporary establishment in greenhouses in other EU territories would be possible. The introduction of D. abbreviatus would likely cause impacts. Measures to prevent entry, spread and impact are available. D. abbreviatus satisfies all the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest., (© 2023 European Food Safety Authority.

Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of Cronartium spp. (non‐EU), a well‐defined and distinguishable group of fungal pathogens of the family Cronartiaceae. There are at least 40 species described within the Cronartium genus, of which two are considered native to the EU (C. gentianeum and C. pini) and one has been introduced in the 19th century (C. ribicola) and is now widespread in the EU – these three species are thus not part of this pest categorisation. In addition, the non‐EU C. harknessii, C. kurilense and C. sahoanum were already dealt with in a previous pest categorisation. All the non‐EU Cronartium species are not known to be present in the EU and are regulated in Council Directive 2000/29/EC (Annex IAI) as harmful organisms whose introduction into the EU is banned. Cronartium spp. are biotrophic obligate plant pathogens. Many of the North American Cronartium species alternate between the aecial host Pinus spp. and telial hosts of various dicotyledonous plants. C. conigenum, C. orientale, C. quercuum and C. strobilinum have different Quercus spp. as their telial hosts. C. orientale and C. quercuum also infect Castanea spp. and Castanopsis spp. The pathogens could enter the EU via host plants for planting and cut flowers and branches. Non‐EU Cronartium spp. could establish in the EU, as climatic conditions are favourable to many of them and Pinus and Quercus spp. are common. The pathogens would be able to spread following establishment by movement of host plants, as well as natural spread. Should non‐EU Cronartium spp. be introduced in the EU, impacts can be expected on pine, oak and chestnut woodlands, plantations, ornamental trees and nurseries. The Cronartium species present in North America cause important tree diseases. Symptoms on Pinus spp. differ between Cronartium spp., but include galls, cankers, dieback of branches and stems, deformity, tree and cone death. The main knowledge gap concerns the limited available information on (sub)tropical Cronartium spp. The criteria assessed by the Panel for consideration of Cronartium spp. (non‐EU) as potential quarantine pests are met, while, for regulated non‐quarantine pests, the criterion on the pest presence in the EU is not met.

Abstract The European Commission requested EFSA to conduct a pest categorisation of Grapholita prunivora (Lepidoptera: Tortricidae), an oligophagous moth whose larvae feed mostly on leaves and fruit of different Rosaceae including cultivated apples, plums, cherries and pecans. It overwinters in soil and bark crevices of its host plants. G. prunivora has reliable identification methods, both for adults and immature stages. It occurs in North America, where it can impact pome and stone fruit production, especially when broad spectrum insecticides targeting pome and stone fruit key pests are substituted by more selective crop protection methods (i.e. mating disruption, biological control). G. prunivora is regulated in the EU by EU Directive 2000/29/EC where it is listed in Annex IIAI using the synonym Enarmonia prunivora. Plants for planting, fruit, cut branches, and bark are potential pathways. Most, but not all hosts are regulated, e.g. pecan (Carya sp.). There are no records of interception of this species on Europhyt. Biotic and abiotic conditions are conducive for establishment and spread of G. prunivora in the EU. Therefore, were G. prunivora to establish, impact on pome and stone fruit production could be expected. Considering the criteria within the remit of EFSA to assess its regulatory plant health status, G. prunivora meets with no uncertainties the criteria for consideration as a potential Union quarantine pest (it is absent from the EU, potential pathways exist, and its establishment would cause an economic impact). Given that G. prunivora is not known to occur in the EU, it fails to meet this criterion required for regulated non‐quarantine pest (RNQP) status.

Abstract The EFSA Panel on Plant Health (PLH) performed a pest categorisation of Grapholita inopinata, (Lepidoptera: Tortricidae), the Manchurian fruit moth, for the territory of the EU. G. inopinata is a well‐defined species that is recognised as a major pest of Malus spp. in Far East Russia, Eastern Siberia and northern China. G. inopinata is less common in Japan where it is not a serious pest. G. inopinata is not known to occur in the EU. G. inopinata is listed in Annex IIAI of 2000/29 EC as a harmful organism regulated on Cydonia, Malus, Prunus and Pyrus from non‐European countries. Adult G. inopinata emerge in the summer, mate and lay eggs on host leaves and fruit. Larvae burrow into the fruit to develop. Larvae exit fruit and overwinter under bark, under leaf litter or in the soil. Import of host fruit provides a potential pathway into the EU. Restrictions on the import of host plants for planting close other potential pathways. G. inopinata occurs in a range of climates in Asia, some of which also occur in the EU. Wild and commercially grown hosts are available within the EU. G. inopinata has the potential to establish within the EU. There could be one or two generations per year as in its native range. Impacts could occur in pome fruit orchards. The level of impacts would be uncertain. Phytosanitary measures are available to reduce the likelihood of introduction of G. inopinata. G. inopinata meets all the criteria assessed by EFSA PLH to satisfy the definition of a Union quarantine pest. G. inopinata does not meet the criteria of occurring within the EU, nor plants for planting being the principal means of spread, so does not satisfy all the criteria for it to be regarded as a Union regulated non‐quarantine pest (RNQP).

Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of Gymnosporangium spp. (non‐EU), a well‐defined and distinguishable group of fungal plant pathogens of the family Pucciniaceae affecting woody species. Many different Gymnosporangium species are recognised, of which at least 14 species are considered not to be native in the European Union. All the non‐EU Gymnosporangium species are not known to be present in the EU and are regulated in Council Directive 2000/29/EC (Annex IAI) as harmful organisms whose introduction into the EU is banned. Gymnosporangium spp. are biotrophic obligate plant pathogens. These rust fungi are heteroecious as they require Juniperus, Libocedrus, Callitropsis, Chamaecyparis or Cupressus (telial hosts) and rosaceous plants of subfamily Pomoideae (aecial hosts) to complete their life cycle. The pathogens could enter the EU via host plants for planting (including artificially dwarfed woody plants) and cut branches. They could establish in the EU, as climatic conditions are favourable and hosts are common. They would be able to spread following establishment by movement of host plants for planting and cut branches, as well as by natural dispersal. Should Gymnosporangium spp. (non‐EU) be introduced in the EU, impacts can be expected in orchards, ornamental trees and nurseries. On telial hosts, these pathogens cause galls on stems, twigs and branches, and fusiform swellings on stems. Foliar infections on aecial hosts may lead to severe defoliations. The main knowledge gap concerns the limited available information on the biology, distribution range and impact of several non‐EU Gymnosporangium spp. The criteria assessed by the Panel for consideration of Gymnosporangium spp. (non‐EU) as potential quarantine pests are met, while, for regulated non‐quarantine pests, the criterion on the pest presence in the EU is not met.

Abstract The Panel on Plant Health performed a pest categorisation of Popillia japonica (Coleoptera: Scarabaeidae) for the EU. P. japonica is a distinguishable species listed in Annex IAII of Council Directive 2000/29/EC. It is native to Japan but established in the USA in the early 20th century. It spreads from New Jersey to most US states east of the Mississippi, some to the west and north into Canada. P. japonica feeds on over 700 plant species. Adults attack foliage and fruit surfaces. They can cause serious injury to tree fruits and soft fruit, vegetable crops, ornamental herbaceous plants, shrubs, vines and trees. Larvae are root feeders regarded as serious pests of lawns and turf, vegetables and nursery stock. Adults emerge during the summer and can fly short distances on warm sunny days. The life cycle is usually completed in one year. In cooler regions, development takes two years. P. japonica occurs in the EU in the Azores (Portugal), Lombardy and Piedmont (Italy) where it is under official control. Adults are suspected of being able to spread on aircraft as hitchhikers, i.e. without host plants. Soil accompanying plants for planting provides a pathway for further introductions. Hosts are widely available within the EU. Climatic conditions across central and parts of southern EU are suitable for development in one year. Across parts of northern Europe development over two years is likely. Without control, impacts could be expected on a range of plants. Phytosanitary measures are available to reduce the likelihood of introduction of P. japonica. All criteria assessed by EFSA for consideration as a potential Union quarantine pest are met. Plants for planting are not necessarily the main means of spread so P. japonica does not satisfy all criteria necessary for it to be regarded as a Union regulated non‐quarantine pest (RNQP).

Abstract The Panel on Plant Health performed a pest categorisation of non‐EU Monochamus spp., a well‐defined insect genus in the family Cerambycidae (Insecta: Coleoptera). Species can be identified using taxonomic keys at national and regional level, and DNA barcoding. Two online world catalogues exist for the genus. The genus includes about one hundred species and many subspecies colonising conifers and non‐conifer trees in many areas in the world. The non‐EU species are listed in Annex IAI of Council Directive 2000/29/EC. Although Monochamus spp. colonise weakened or dead trees and have therefore no direct impact, some species vector the pine wood nematode, Bursaphelenchus xylophilus, which they inoculate to healthy trees when they proceed to maturation feeding on twigs, causing high mortality among pines in Asia and the EU (Portugal). Sixteen species in Asia and America attack conifers. The main pathways for entry are raw untreated wood and wood products, wood packaging material, particle wood and waste wood, finished wood products and hitchhiking. Monochamus species were categorised in two groups. The first group includes 16 species colonising conifers and absent in the EU known or likely to vector the pine wood nematode. The species in this group satisfy all the criteria to be considered as Union quarantine pests. Measures are in place to prevent the introduction of Monochamus with coniferous wood. The second group gathers all the remaining species, all non‐EU species colonising non‐conifers. These do not satisfy all the criteria to be considered as Union quarantine pests. As plants for planting are not a pathway for Monochamus spp., and as most of the species within these groups are absent from the EU territory, the two groups do not meet the criteria to be considered as regulated non‐quarantine pests.
