Entomocomplex of peach plantations in the vegetation period

Abstract

Goal. Study of the entomocomplex of peach plantations in order to plan appropriate measures to limit their harmfulness.
 Methods. Laboratory field. The population of peach trees by pests was determined according to generally accepted methods in the Research Garden of the Dmytro Motorny Tavriya State Agrotechnological University. Census counts were conducted in peach plantations of the Crimean Fireworks, Jubilee Sidorenko, Redhaven, Skazka, Vireney and Ambassador of Peace varieties.
 Results. It was found that in the agrocenosis of peach plantations during 2018—2019, three permanent species of pests were registered: California thymus (Quadraspidiotus perniciosus Comst.), Turkestan mite (Tetranychus turkestani Ud. Net Nik.) And eastern fruit eater (Grapholitha molesta Busck). The adult age of the last phytophagous began with the beginning of flowering peach trees and lasted until September. The number of butterflies in pheromone traps varied during the growing season from 24.7 to 48.5 specimens / trap, ie significantly exceeded the economic threshold of harmfulness. It should be noted that despite the very high age of the pest in the experiment, damage to peach shoots in all varieties (except Crimean fireworks and the Ambassador of Peace) was below the economic threshold of harmfulness (0.1—1.0%). The population of peach leaves by Turkestan mite on different varieties was 0.1—1.5 specimens / leaf. Studies on the peculiarities of the development of the Californian thyroid have shown that the beginning of the flight of males of the first generation was recorded in pheromone traps in the second decade of May. In 2019, this phase of development is marked a week later. The revival of traveling larvae also occurred at different times, with slight fluctuations. The number of California thyme on peach varieties ranged from 0.8 to 17.2 specimens / shield.
 Conclusions. On peach cultivars the California thyme (up to 17.2 specimens/shield), oriental fruit fly (from 0.3 to 2.5 specimens/shoot) and Turkestan spider mite (up to 23.8 specimens / leaf) were noted, depending on The high potential of California thyme reproduction in peach plantations on the Crimean Fireworks, Virenea and Ambassador of Peace varieties has been recorded.

Integration Vectors of Sustainable Development: Economic, Social and Technological Aspects

“…In recent years the pest has gained the economic importance not only for the fruit, but also for the field crops including the oil producing cabbage crops. The damage is caused by the beetles which gnaw out the flowers of fruit trees, rose, rose-bush, rowan tree, June berry, almond, lemon, tangerine, grapes (buds, ovaries and young leaves), horse chestnut, snowball-tree, lilac, privet, beetroot, elderberries, golden currant, black currant (young leaves and flowers), Elea gnus, peony, poppy, black radish, rocket salad, rape, mustard, cabbage (seeds), beet (transplants), common flax, rhubarb, cucumbers, watermelons, melons, pumpkin, ambary hemp, cotton, castor-oil plant, strawberries, holy clover, peas (leaves and sprouts), clover, vetch, beans, soybeans, haricot, alfalfa, gram chick-peas, sunflower, safflower, tomato, daisy, tulip, ears of rye, wheat, barley, panicles of millet, corn and other plants (Rozova, 2011;Chernii, 2011).…”
