Monitoring of gardens and parks plantations in the Ukraine Forest-steppe zone
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.
