Структура та домінування видового ентомологічного біорізноманіття листяних біотопів Київського Полісся

Taking into account anthropogenic and climatic factors, which pose a threat to biodiversity, the study of the real state, observation and preservation of the dominant species of entomological biodiversity is extremely relevant. The purpose of this work is to determine the condition, structure and dominance of the entomological species biodiversity of the leafy biotopes of Kyiv Polissia. The studied area was selected for monitoring sites in leafy biotopes of the Kyiv Polissia near the listed settlements: Sukholuchchya, Tolokun, Yasnogorodka, which are located in Vyshgorod district of Kyiv region. Methods, which are tested and recommended for field and laboratory research in entomology, plant protection, and ecology, were used for accounting. Important aspects of research are skills of collecting and analyzing primary information, assessing species richness and diversity, and determining the level of dominance of individual species in the biotope. Collection and accounting of entomological biodiversity were carried out according to generally accepted methods once every 7–10 days at stationary sites. The state and structure of the entomological biodiversity of the leafy biotopes of Kyiv Polyssia in 2022–2024 were studied. As a result of the monitoring and accounting of the entomological biodiversity in the leafy biotopes of Kyiv Polyssia of Ukraine, 286 species of insects from 51 families of 6 orders were found (phytophages (dominant, omnivorous, specialized), entomophages, pollinators, inert species, etc.). In terms of families and species, the dominant one is the order of Coleoptera, which includes 187 species from 22 families being equal 65.3% of the total amount of studied entomological biodiversity. 6 families had the largest number of species: Ipidae — 30, Curculionidae — 26, Cerambycidae — 25, Aphididae — 19, Chrysomelidae — 18, Buprestidae — 18 (46% of the total number of species). The number of dominant species of insects in the leafy biotope ranged from 60 to 257 specimens per accounting unit. The most numerous species were Melolontha melolontha Linnaeus, 1758 — 257 specimens; Lampronia pubicornis Haworth, 1828 — 218 copies and Psylla betulae Linnaeus, 1747 — 186 sample. Based on the results of the research, the list was compiled and analysis of the current state of the entomofauna of deciduous biotopes in the research region was carried out.
