The article represents research findings as for the species composition identification of the arthropod-pests of the genus Sorbus. The study was conducted in the period from April to October during several years in greenery on the territory of Kyiv and the Kyiv region. Four groups of pests were distinguished: pests of root system (6 species), pests of leaves (18 species), pests of fruits (2 species), pests of sprouts (4 species). Twenty-nine species of arthropods of the hexapods (Insecta) which

... belong to the 6 numbers of plant groups and 1 species of acariform mites (Acariformes, Arachnida) were found and identified. The most numerous species were arthropod pests, the representatives of the order Coleoptera – 10 species – and Lepidoptera – 8 species. The greatest damage caused by pests at different stages of their biological development was inflicted on the leaf cover of rowan – 60%, and its root system – 20%. Significant damage to rowan plants was caused by pests – polyphagous: Gryllotalpa gryllotalpa L., Psylla mali Schm., Aphis pomi De Green, Rhopalosiphum insertum Wal., Edwardsiana rosae L., Lepidosaphes ulmi L., Operophtera brumata L., Мelolontha melolontha L., Selatosomus aeneus L., Scolytus mali Bech., Phyllobius argentatus L., Agrotis segetum Den.et Schiff., Yponomeuta melinellus L., Simaethis pariana L., Argyresthia conjugella Zell., Pentatrichopus sp. The thorough analysis of damage to various parts of plants was carried out. In most instances, the greatest damage by pests to plants was observed on densely clustered plantations of rowan compared to single and small groups of trees and the presence of plants of the family Rosaceae as an additional forage base. The physiological condition of plants was significantly worsened by the adverse impacts of critical environmental factors. The damage to rowan by pests had a clear mosaic character and depended on various biotic and abiotic environmental factors.
