Fall Webworm Moth

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.

Physiological And Biochemical Properties

Strains of Bacillus thuringiensis effecient against leaf-chewing insects of Lepidoptera and Diptera genus have been isolated from insects of nature populations. Their physiological and biochemical properties and the spectrum of entomopathogenic action were studed. The activity of pathogens against the larva of potato beetle (Leptinotarsa decemlinaeta, order Coleoptera), caterpillars of cabbage moth (Mamesta brassicae, order Lepidoptera) and fall webworm moth (Hyphantria cunea Dryri, order Lepidoptera) of small age grade was around 74,7-100 %. These strains were added to bacterial entomopathogene collection of the Institute of agricultural microbiology of UAAS as perspective for elaboration of biopreparations for plants protection against leafchewing insects.

Diapause Incidence

Abstract The accumulation of nutrients during diapause preparation is crucial because any lack of nutrition will reduce the likelihood of insects completing diapause, thereby decreasing their chances of survival and reproduction. The fall webworm, Hyphantria cunea, diapause as overwintering pupae and their diapause incidence and diapause intensity are regulated by the photoperiod. In this study, we test the hypothesis that photoperiod influences energy reserve accumulation during diapause preparation in fall webworm. We found that the body size and mass, lipid and carbohydrate content of pupae with a short photoperiod during the diapause induction phase were significantly greater than those of pupae with a relatively short photoperiod, and the efficiency of converting digested food and ingested food into body matter was greater in the short-photoperiod diapause-destined larvae than the relatively short-photoperiod diapause-destined larvae. We also observed higher lipase and amylase activities in short-photoperiod diapause-destined larvae relative to the counterparts. However, no obvious difference was found in protein and protease in the pupae with a short photoperiod during the diapause induction phase and short-photoperiod diapause-destined larvae compared with the counterparts. Therefore, we conclude that the energy reserve patterns of diapausing fall webworm pupae are plastic and that short-photoperiod diapause-destined larvae increase their energy reserves by improving their feeding efficiency and increase their lipid and carbohydrate stores by increasing the lipase and amylase activities in the midgut.
