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.

Enantioselective Syntheses

Background: The Diels-Alder reaction has been widely utilised in the syntheses of biologically important natural products over the years and continues to greatly impact modern synthetic methodology. Recent discovery of chiral organocatalysts, auxiliaries and ligands in organic synthesis has paved the way for their application in Diels-Alder chemistry with the goal to improve efficiency as well as stereochemistry. Objective: The review focuses on asymmetric syntheses of flavonoid Diels-Alder natural products that utilize chiral ligand-Lewis acid complexes through various illustrative examples. Conclusion: It is clear from the review that a significant amount of research has been done investigating various types of catalysts and chiral ligand-Lewis acid complexes for the enantioselective synthesis of flavonoid Diels-Alder natural products. The results have demonstrated improved yield and enantioselectivity. Much emphasis has been placed on the synthesis but important mechanistic work aimed at understanding the enantioselectivity has also been discussed.
