Abstract
The article presents data on the ecological and phytosanitary condition of green plantations of Osh city. The general reasons for the weakening, drying, and decrease of the decorativeness of green plantings of the city are the insufficiency of agrotechnical measures and watering in hot summer time, violation of rules of planting of plantations, outbreaks of mass reproduction of diseases and pests, and imperfection of protective measures against pests and diseases. The dominant insect pests of tree and shrub plantations of Osh city, including 56 species of insects, were identified. The overwhelming majority of pests belonged to the detachments: Lepidoptera—17 species, Hemiptera—12, Homoptera—11. In 2024, in Osh city and its countryside, an outbreak of mass reproduction of oak miner sawfly (Profenusa pygmaea Klug, 1816) on oak plantations and elm miner sawfly (Fenusa ulmiSandevall, 1844) on elm was observed; small mulberry firefly (Glyphodes pyloalis Walker, 1859) on mulberry, willow leaf beetle (Plagiodera versicolora Laicharting, 1781), willow leaf beetle (Xanthogaleruca luteola Statius Müller, 1766), and oriental leaf beetle (Agelastica orientalis Baly, 1878) on elm, willow, and poplar trees. The results of the application of the biological preparation Actorophyte 1.8 showed 93-100% biological efficiency in the control of oak and elm miner sawflies and small mulberry fireflies.
