Black chokeberry (Aronia melanocarpa L.) is a fruit-bearing shrub that has come to the attention of growers due to the content of antioxidants and vitamins in the fruit. Being a perennial crop, it provides stable habitats for both useful and harmful entomofauna. The aim of the work was to evaluate the diversity of existing arthropods in an aronia plantation within the experimental plots of RSFG Iaşi. The experience was organized in four variants: V1- in which approved treatments for ecological agriculture were applied; V2- ecological treatments and irrigation, V3- in which approved conventional treatments, V4-conventional treatments and irrigation, each variant having three repetitions. Arthropod densities were sampled using Barber-type soil traps, in which the fixing solution was sodium chloride (NaCl) with a concentration of 25%. The harvestings were made periodically, from the beginning of May to the end of September 2022. The structure of the collected material varied according to the experimental variant. The arthropod fauna was made up of species that systematically fall into the following orders: Coleoptera, Hymenoptera, Heteroptera, etc. [ABSTRACT FROM AUTHOR]

This research was carried out in 2020-2022, from May to September in each year. The entomological material that is the object of this study was collected from three corn agroecosystems located in three stationary from Iasi County, Romania: Ezăreni, Trifeşti, and Schitu Duca. To achieve the objectives of the research, four variants were used: V1, superficial tillage in the spring and untreated seeds; V2, deep tillage during autumn plowing and untreated seeds; V3, superficial tillage in the spring and treated seeds; and V4, deep tillage during autumn plowing and treated seeds. Biodiversity characterization indexes, namely the biodiversity index, the Shannon diversity index, equity, and the Simpson diversity index, were used to quantify biodiversity in the habitats. Data analysis and interpretation were carried out with the help of the BIODIV application to calculate the main biodiversity indicators. In our opinion, these comparative studies on the Carabidae fauna in relation to current pest control methods are useful in agricultural practice. [ABSTRACT FROM AUTHOR]

Boxwood (Buxus spp.) is one of the most popular ornamental plants grown in landscaping due to its green foliage and low maintenance requirements. Commercial varieties of boxwood are propagated by cuttings, and the life cycle of the plant in the nursery can vary depending on the culture technology. The experience took place in the period 2022-2023 within a subunit of the ROMSILVA National Forest Management, in the Ia537;i area. The aim of this study was to evaluate the existing entomofauna within the three variants established in the breeding grounds. The material was collected using the Barber-type soil traps every year from the beginning of May to the end of September, with a difference of 10-14 days. The obtained results revealed a different structure of the taxonomic groups during the study period, the weights being directly influenced by the climatic conditions. From the analysis of the collected entomofauna, species belonging to 12 orders were identified. The most representative was the order Hymenoptera 27.35%, followed by the order Isopoda (19.72%) and the order Coleoptera with a value of 17.49%. [ABSTRACT FROM AUTHOR]

The species Diabrotica virgifera virgifera Le Conte is known as a dangerous pest of maize. The insect was monitored at ARDS Secuieni in the period 2021-2023, with the help of yellow traps with glue, but also pheromonal ones placed in maize crops. During the three years of monitoring, the presence of this species was observed in the maize crops in the Central area of Moldova, totaling an average number of 663 specimens. The flight of the species started in the first decade of July in all monitored years, and continued until the end of September in 2021 and 2022, respectively until the first decade of October in 2023. The maximum flight peak of was different each year, registering in the third decade of July in 2021, in the first decade of August in 2022 and in the third decade of August in 2023. On average, the flight of the species started in the first decade of July and continued throughout the maize vegetation period, the maximum flight peak being recorded in the first decade of August.

The species Diabrotica virgifera virgifera Le Conte (western corn rootworm) belongs to the order Coleoptera, family Chrysomelidae. It originates from North America and entered in Europe in 1992, in Yugoslavia. It entered in Romania in 1996, when three specimens were recorded in Nădlac (Arad county), and since then the range of the pest has continuously expanded (Manole, 2017). To reduce the spread of this pest, it is recommended to avoid monoculture and practice rotation. It can reduce the root attack to a minimum level, the larvae not being able to survive in soils cultivated with other plants (Ciobanu, 2009). The most common strategies used to protect maize roots against the pest Diabrotica virgifera virgifera are the application of an insecticide to the soil at seeding and the use of an insecticide in the seed treatment (Sutter et al., 1990). The average number of larvae per plant varied from 1 to 5, the fewest larvae being recorded in the variant where the granular insecticide Force G was applied to the soil at a dose of 15 kg/ha. The frequency of swan neck ranged from 0% to 58%. The attack produced by adults on the leaf recorded frequencies between 32% and 66%, and on maize silk, the attack was 100%. The average number of adults per plant was between 9 and 10. [ABSTRACT FROM AUTHOR]

To collect the material, were used Barber soil traps of the wet type, in which a 20% sodium chloride (NaCl) solution was placed. There were used 3 variants, each with 6 repetitions, as follows:V1, in which treatments were applied against pests, with products approved for organic agriculture; V2, in which treatments were applied against pathogens and pests in conventional agriculture; V3, in which no pest control treatment was applied. Collections of the captured material were made during the months of June, July and the first decade of August. The insect species collected belong to the following orders: Coleoptera, Hymenoptera, Diptera, Homoptera, Heteroptera, etc. [ABSTRACT FROM AUTHOR]

The species Diabrotica virgifera virgifera Le Conte (western corn rootworm) is part of the order Coleoptera, family Chrysomelidae and is an invasive alien species native to Central or South America. In Europe, it was reported in 1992, and in Romania in 1995. The attack produced by the species Diabrotica virgifera virgifera significantly reduces maize production, the pest being a carrier of various pathogens that cause crop plant diseases (Bacal et al, 2020). In the present paper, are presented partial results regarding the appearance, evolution and flight of adults of the species Diabrotica virgifera virgifera, respectively, the attack that the insect produces in the maize crops in the Central area of Moldova. In the year 2021, the flight of this species began in the first decade of July and continued until the third decade of September. The maximum flight peak was achieved in the third decade of July, being 180 specimens/trap. In the year 2022, the flight of the species started in the first decade of July and continued until the end of September. The maximum flight peak was recorded in the first decade of August, when a number of 182 specimens/trap were collected. In the year 2022, a maize silk attack frequency of between 85% and 100% was recorded. From the results obtained in 2022, the treatment carried out on the vegetation with insecticides reduced the number of adults per plant from 1.6 specimens to 0.1 specimens. [ABSTRACT FROM AUTHOR]

This paper reports the results obtained from the analysis of capture data using the TERASEYA FLY device for Lobesia botrana males (Denis and Schiffermüller). The research was carried out in the region of Moldova, within two plantations belonging to two representative wine basins in the country, being the Odobesti Vineyard and the Husi Vineyard. In the study areas, the vineyards (of Vitis vinifera L.) are cultivated mostly with quality wine varieties, predominantly in the Odobesti vineyard we meet the Muscat Ottonel variety, and in the Husi vineyard we meet the Fetească regala variety, which have also been the subject of research our. The main aim of the study was to investigate the dynamics and biology of L. botrana species inside vineyards and to assess the effect of new climate change on pest distribution. Pest prediction and warning models have been developed and tested to monitor the life cycle of L. botrana, integrating both biological and climatic information. The timing of the first appearance of adults and the hatching of the first eggs can be predicted by predictive models based on the temperature requirements of the stages. Unfortunately, the models of prediction based on the calculation of the sum of daily degrees of temperature are empirical and their robustness strongly depends on the environment in which they were validated. The alternative forecasting techniques are currently being developed, such as pest assessment in the study area using these modern digital farming techniques. [ABSTRACT FROM AUTHOR]

The pest Cydia pomonella L. is present in all countries where the apple tree is grown (CABI 2021), the damage done by this species being considerable. The lower threshold of development of the species under study is 9°C that influences the appearance in apple plantations of butterflies, it was recorded in the analyzed area on May 9 in 2019 and May 1 2020, a period during which the sum of the temperature degrees did not meet the thermal constant (K) of the species worth 624°C (Rosca I. et al., 2011). The research was carried out between 2019-2020 at the Research Station for Fruit Growing Iasi, Romania using AtraPom traps (ICCRR Cluj-Napoca) to determine the biological cycle of the Cydia pomonella L. species in correlation with the influence of changes in climatic conditions.

Maize is cultivated on 2,678.5 thousand ha in Romania, and its cultivation on large areas attracts a number of pests that attack various parts of the plant in different developmental phases. One of these dangerous pests is Ostrinia nubilalis Hbn., a species that occurs during the growing season of maize and causes production losses by the attack on the stem and cob. The larvae produce various attacks, influenced by climatic conditions, the frequency of attacked plants being between 15.7 and 67.9% in the south-west of the country, in the south-east of the country varies between 43.3-79.4%, in the Transylvanian Plain has values between 60.00% and 81.88%, in the west of the country the attack is around 41%, and in the east of the country by 30.20%. The importance of attacks by Ostrinia nubilalis Hbn. at maize led to the initiation of studies in 2019 at the A.R.D.S. Secuieni to determine the influence of technological factors on the parameters of attack (frequency of attack, average number of holes, galleries and larvae and average length of gallery) produced by larvae. For the maize sown in epochs, the optimal epoch, the IIIrd, recorded the lowest values of the parameters: the frequency of the attack was 18.65%, were identified 0.60 holes/plant, 0.39 galleries/plant and 0.38 larvae/plant, and the average length of the galleries was 8.39 cm. The behavior of genotypes at the attack produced by larvae varied within very wide limits, the frequency of the attack was between 36.56% at the early genotype Vibrion and reached 48.50% at the late genotype Olt.

During the research period, at the Sarca stationary belonging to SCDP Iasi, were studied two walnut plantations, one represented a plantation in which was developed a technology that included the application of chemical treatments, and the other stationary was also represented by a walnut orchard in which no were applied methods of protection against diseases and pests. In order to estabilish the structure and the ecological parameters representative of the coleopters entomofauna from the two plantations, were placed six soil traps type Barber, which had as fixing liquid a salt solution (NaCl) in a concentration of 25%, but the method of tapping was also used. The material was harvested periodically, at intervals between 7 and 14 days, and at each collection the biological material from the traps was transferred from the trap to a gauze cloth, was labeled, and the fixing liquid was filled or replaced according to case. Larger, significant differences appear from one stationary to another, which indicates that the technology with the treatment scheme applied in vegetation has a great influence on the entomofauna in general.

The research was carried out within SCDP Iaşi, in two lots with a different crop technology. The observations concerned the entire entomofauna of arthropods from a walnut orchard where a conventional cultivation technology was applied and in a walnut orchard where ecological methods of protection against diseases and pests were applied. The research was carried out during 2018-2019, when the method of soil traps Barber type was used, while the flight curve of the pest Cydia pomonella was followed with help of synthetic pheromones traps, AtraPom type. The observations were made throughout the vegetation period, from May to September, having as research material 4 walnut genotypes, in the seventh year after planting, being grafted on Juglans regia. In the case of the conventional variant, phytosanitary treatments with fungicides and insecticides were performed, and in the ecological walnut variant, no phytosanitary treatments were performed, pest control being performed using biotechnical means, using only traps with synthetic sex pheromones AtraPom. During this period, climatic factors were also analyzed, which influence the biology of useful and harmful species. Following the monitoring and determination of all species collected, data were recorded on the abundance and dynamics of existing fauna. [ABSTRACT FROM AUTHOR]

From the first report of the species Ostrinia nubilalis Hbn. in Romania in 1898, the insect spread and is currently present in all corn crops in our country. The production losses that the insect produces vary from one year to another, from one field to another, one of the factors influencing the reduction of the attack is the cultivated maize hybrid. This paper presents the preliminary results obtained in 2019, where was studied the influence of the precocity group and the hybrid variety on the attack level produced by the european corn borers larvae in the conditions of the Center of Moldova. The studied maize hybrids show different values of the attack produced by the Ostrinia nubilalis Hbn. larvae. Depending on the maturity group, the genotypes that recorded high attack values are those from FAO groups 400 - 430 (Kerala and Olt), followed by semi-early hybrids in FAO groups 370-380, and the lowest attack was recorded by the hybrid Vibrion maize classified as FAO maturity group 290. Of the three maize varieties tested, the sweet hybrid was the most affected by the european corn borer larvae attack followed by the dentate ones from the semi-early maturity groups and the flint variety (Vibrion) was not affected due to the short period of vegetation.

This paper summarizes the literature on the main pest control methods of plum orchards. The purpose of the paper is to present the state of knowledge on the main pest control methods of plum plantations existing in our country and beyond. The research was made based on comparative studies and case studies based on data from the specialized literature. Integrated pest management is a system of measures using all available methods, including biological and agrotechnical, as well as pesticides, to predict and prevent economic damage caused by pests. Pests are any organisms, including weeds, insects, disease pathogens, which are harmful to the planting, crop growth, harvesting and marketing of the fruit. Integrated pest management is a good practice in horticulture because, potentially, it can increase productivity, reduce costs and contribute to the stability of agriculture and environment. As a general conclusion, plum pests can be combated by both conventional and unconventional methods. [ABSTRACT FROM AUTHOR]

Lately, mining moths were observed in apple orchards with very strong attacks. Emergence of strong infestations depends on many factors, but the most important climatic factor is temperature. It is known that in plant protection, climatic conditions have a very important role in pest evolution. In 2010 - 2011, at S.C.D.P. Iaşi was followed the evolution of mined insects, in apple orchard, through an analysis of climatic factors. Observations were made on the predominant species: Phyllonorycter corylifoliella Hbn and Phyllonoryctre blancardella F. In both species was monitored the dynamic attack depending on weather conditions, which were taken by the AgroExpert Weather Station. Following biological observations, was found that in 2010, the emergence of biological stages for both species was achieved much earlier than in 2011. It depends on climatic factors, especially temperature, factors that determine the number of generations for these pests. In the environmental conditions of Iasi county, both species (Phyllonorycter blancardella and Phyllonorycter corylifoliella) showed 3 generations per year. [ABSTRACT FROM AUTHOR]

Interdependence between the thermal regime of the soil and the depth at which there is the most significant hypothermia tolerance was put into evidence under 2006-2009. In 2006, after a more severe winter, the most numerous hibernating adults were recorded in the layer of 31-40 cm, while in other years at a depth of 26-30 cm. Below and above these depths hibernating adult population has diminished under the years 2007 to 2009. This is due to hypothermia in the superficial layers of the soil, and in the deepest (below 30-40 cm), adults debilitation, as a result of increased consumption of carbohydrates and fats during break time and high crossing thicker soil layer.

From all meteorological factors, first were studied effect of temperature and humidity, because these factors influence the breeding intensity and further development of the insect. An analysis of climatic fluctuations in Suceava, suggests that the winters in a certain extent have warmed, the precipitation quantities from the cold season and summer temperatures have increased considerably, which makes the insect development and biology to default other facets to years of occurrence in the Suceava. Taking into consideration the data recorded during 2006-2009, the average adult stage from hibernate adult emergence in G1, until to pontes depositing was on average 18 and 16 days. If in 2006-2008 duration of this phase do not differ significantly between the two appearances of adults, in 2009 duration of the same stage was eight days longer in the first phase compared to the second stage. This major difference can be attributed to the large number of days (ten) with low temperatures. [ABSTRACT FROM AUTHOR]
