Broun I. Green apple aphid (Aphis pomi Deg.) and protection from it in the Right-Bank Forest-Steppe of Ukraine

The species composition of pests of fruit and ornamental nursery crops in the Right-Bank Forest-Steppe of Ukraine was studied. There are 49 species of insect pests of 6 orders and 26 families were identified. The greatest diversity of species characterized by a detachment of Coleoptera, which was accounting for 37.3 % of the total number of phytophagous were found. Characterized by a smaller number of Homoptera (29,3 %) and Lepidoptera (17,7 %). Green apple aphid (Aphis pomi Deg.) is on the more of the fodder plants. It is damages of different kinds of apple, pear, cotoneaster and other plants of the Rosaceae. Biology and harmfulness of the green apple aphid were studied. The species composition of forage plants of Aphis pomi in the area of research, which belonged to Rosaceae family, and was represented by 12 genera and 37 species. Reduced of the growth of branches, leaf area, the contents of the primary and hygroscopic moisture, as well as chlorophylls and carotenoids in the damaged leaves of Aphis pomi was studied. The species composition of entomophages of Aphis pomi in the area of research was conducted. The efficiency of biological preparations, insecticidal plants and insecticide for the control of green apple aphid was discovered. Among biological preparations against green apple aphids high efficiency (94,5 %) was shown by Aktofit, k. e. (2,0 l/ha). The most technical effectiveness against Aphis pomi showed by Konfidor, 20 % v.r.k. (0,25 l/ha); Konfidor Maxi, 70% v.g. (0,07 kg/ha), Calypso 480 SC, k.s. (0,25 l/ha) and Decis Profi 25 WG, v.g. (0,10 kg/ha), whose actions at the maximum application rate was destroyed by 98,6-99,9 % of pest
