В последние три десятилетия произошли существенные изменения в видовом составе доминирующих вредителей древесных растений Санкт-Петербурга и окрестностей. За это время в насаждениях города появились три новых инвазионных вредителя из семейства молей-пестрянок (Gracillariidae), минирующих листья древесных растений: липовая моль-пестрянка Phyllonorycter issikii, каштановая минирующая моль Cameraria ohridella и дубовая широкоминирующая моль Acrocercops brongniardella. Впервые в Санкт-Петербурге эти виды отмечены в 2000, 2013 и 2018 гг. соответственно. Все три вида дают вспышки массового размножения во вторичном ареале. Кроме того, началось массовое размножение ещё одного вида из этого же семейства тополёвой нижнесторонней моли-пестрянки Phyllonorycter populifoliella. В других систематических группах вредителей также преобладают скрытноживущие виды: минирующие листья листоеды Zeugophora subspinosa и листоед большеног Zeugophora flavicollis на тополе, пилильщики Ardis pallipes, Arge ochropus и Blennocampa phyllocolpa на розе морщинистой, запятовидная щитовка Lepidosaphes ulmi и тля Eriosoma lanigerum на боярышнике. При этом ранее эти насекомые как вредители насаждений Санкт-Петербурга не отмечались. С другой стороны, ряд видов насекомых-филлофагов, в особенности открытоживущих, для которых ранее было отмечено резкое неоднократное увеличение плотности популяций, за последние 40 лет не встречались в городских насаждениях, например, три вида волнянок (Erebidae) шелкопряд-монашенка Lymantria monacha, ивовая волнянка Leucoma salicis и античная волнянка Orgyia antiqua. Ещё одна значимая группа вредителей сосущие насекомые, которые широко представлены в городских насаждениях и периодически дают значимые увеличения численности. Изменение видового состава доминирующих групп вредителей в городской среде может быть связано с тремя основными внешними факторами, воздействующими на популяции это изменение породного состава насаждений, изменение климата и повышение уровня загрязнения и других антропогенных нагрузок на насаждения. Последний фактор, весьма вероятно, и обусловливает доминирование скрытноживущих и сосущих вредителей. In the last three decades, significant changes have occurred in the species composition of the dominant pests of woody plants in St. Petersburg and its environs. During this time, three new, invasive pests from the moth family Gracillariidae that mine the leaves of woody plants appeared on the plantings of the city: the lime leaf miner Phyllonorycter issikii, the horse-chestnut leaf miner Cameraria ohridella and the leaf blotch miner moth Acrocercops brongniardella. These species for the first time were recorded in St. Petersburg in 2000, 2013, and 2018 respectively. All three species give outbreaks in the secondary range. In addition, the outbreak of another species from the same family, the poplar mining moth Phyllonorycter populifoliella, began. Species leading a secretive life are also dominated in other systematic pest groups: leave miners the leaf beetles Zeugophora subspinosa and Zeugophora flavicollis on the poplar, sawflies Ardis pallipes, Arge ochropus and Blennocampa phyllocolpa on the rugosa rose, the apple mussel scale Lepidosaphes ulmi and the aphid Eriosoma lanigerum on the hawthorn. Moreover, earlier these insects as pests of the stands of St. Petersburg were not noted. On the other hand, a number of phyllophagous insect species, especially open-living insects, for which a sharp repeated increase in population density was previously noted, have not been found in urban plantations over the past 40 years, for example, three species of family Erebidae the nun moth Lymantria monacha, the satin moth Leucoma salicis and the rusty tussock moth Orgyia antiqua. Another significant group of pests is sucking insects, which are widely represented in urban plantations and periodically give significant increases in numbers. The change in the species composition of the dominant pest groups in the urban environment can be associated with three main external factors affecting populations: a change in the species composition of the stands, climate change, and an increase in the level of pollution and other anthropogenic pressures on the stands. The latter factor, very likely, determines the dominance of secretive and sucking pests.

Goal. To monitor the phytosanitary state of parks and gardens plantations in the Ukrainian Forest-steppe zone and to identify species consistence of the dominant invaders. Methods. Reconnaissances, collection of materials and other attendances were carried out by using generally known ecology and entomology methods using determinants and atlases. Accounting results were subjected to variation-statistical analysis by special application program package according to the statistics and computer graphics: Microsoft Excel 2010, Statgraphics plus. Results. As a result of the phytosanitary state of the parks and gardens plantations in the forest-steppe zone were determined phytophagans species composition including 14 species of invaders among which were dominated Lepidopterans species (70.4%). Less numerous species were expanded forms of Coleoptera — 13.4%, Dipteran — 12.8% and other species which were 3.4%. The most widespread gardens and parks plantations invaders are: chestnut leaf miner (Cameraria ohridella Deschka & Dimic), fall webworm moth (Hyphantria cunea Drury.), linden moth (Phyllonorycter issikii Kumata), acacia lotus borer (Etiella zinckenella Tr.). Among the fastest spreading invaders is boxen lotus borer (Cydalima perspectalis Walker) (common box) from South-East Asia. In Ukraine this species was discovered in 2016 in Transcarpathia region. Conclusion. Over the last years destructive plant feeders such as: horse chestnut leaf miner, fall webworm moth, linden moth and others became more spreading within the parks and gardens plantations of the Ukrainian Forest-steppe zone. The significant injury by adventive species — boxen lotus bore was discovered. The lack of well-timed gardens and parks monitoring in the Ukrainian Forest-steppe zone led to mass distribution of lots of harmful species both quarantine and invasitions.

Abstract A part of the COI mitochondrial barcoding gene was sequenced from seven species of different taxonomical groups: Ambystoma mexicanum (Amphibia, Ambystomatidae), Darevskia lindholmi, Lacerta agilis exigua (Reptilia, Lacertidae), Erinaceus roumanicus (Mammalia, Erinaceidae), Macrobiotus sp. 1 and 2 (Eutardigrada, Macrobiotidae) and Cameraria ohridella (Insecta, Gracillariidae). The sequences were compared with available sequences from databases and positioned on phylogenetic trees when the taxa had not yet been sequenced. The presence of Mexican axolotls in herpetoculture in Ukraine was confirmed. The partial COI genes of the Crimean rock lizard and an eastern sub-species of the sand lizard were sequenced. We demonstrated the presence of two tardigrade mitochondrial lineages of the Macrobiotus hufelandi group in the same sample from the Zeya Natural Reserve in the Far East: one was nearly identical to the Italian M. macrocalix, and the other one is similar to M. persimilis and M. vladimiri. We also confirmed the presence of the invasive haplotype “A” of the horse chestnut leaf miner in Ukraine, in line with the hypothesized route of invasion from Central Europe.

Abstract Background In this study, commercial bioinsecticides including entomopathogenic fungi, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, and Spinetoram active ingredient insecticide were evaluated against the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) larvae. Main body The active ingredients were prepared at the recommended concentrations under laboratory conditions and applied to the 2nd instar larvae of T. absoluta by spraying with a hand sprayer. On the 1st, 3rd, 5th, and 7th days of the application, evaluations were made by counting survived individuals. The findings showed that the highest mortality rates were detected in the case of Spinetoram with 56, 60, 88, and 100% on all counting days of the experiments, respectively. The highest mortality rate among bioinsecticides was recorded for M. anisopliae, with 87% mortality on the 7th day of application. Short conclusion As a result, Spinetoram was found the most effective insecticide when applied to T. absoluta, followed by M. anisopliae.

The chickpea leafminer, Liriomyza cicerina (Rondani), is one of the most destructive insect pests of cultivated chickpea (Cicer arietinum L.) in the Mediterranean region under field conditions. For sustainable and environmentally friendly chickpea production, efforts have been devoted to managing the leafminer via decreasing the use of insecticides. Breeding of new resistant varieties is not only an efficient and practical approach, but also cost-effective and environmentally sensitive. To improve resistant varieties, breeders need reliable biochemical selection criteria that can be used in breeding programs. The first objective was to investigate the possible introgression of resistance to the leafminer from C. reticulatum Ladiz. (resistant) to C. arietinum (susceptible), then, to estimate inheritance of resistance to the leafminer for efficient breeding strategies, and finally, to study organic acid contents as selection criteria. Recombinant inbred lines (RILs) and their parents were evaluated using a visual scale of 1–9 (1 = free from leafminer damage and 9 = mines in more than 91% of the leaflets and defoliation greater than 31%) in the field under natural infestation conditions after the susceptible parent and check had scores of >7 on the visual scale. Superior RILs were found for resistance to the leafminer, and agro-morphological traits indicating that introgression of resistance to leaf miner from C. reticulatum to C. arietinum could be possible using interspecific crosses. The inheritance pattern of resistance to the leafminer in RILs was shown to be quantitative. Organic acids, including oxalic, malic, quinic, tartaric, citric and succinic acids in RILs grown in the field under insect epidemic conditions and in the greenhouse under non-infested conditions were detected by using high performance liquid chromatography (HPLC). In general, organic acids were found to be higher in resistant RILs than susceptible RILs. Path and correlation coefficients showed that succinic acid exhibited the highest direct effects on resistance to the leafminer. Multivariate analyses, including path, correlation and factor analyses suggested that a high level of succinic acid could be used as a potential biochemical selection criterion for resistance to leafminer in chickpea. Resistant RILs with a high seed yield resembling kabuli chickpea can be grown directly in the target environments under leaf miner infestation conditions.
