Abstract
The article presents data from scientific studies conducted in 2024–2025, which, based on the results of long-term research, revealed the mortality of adult parasitic entomophages as a consequence of the widespread use of systemic pesticides in the forest biocenosis. In order to improve integrated control measures against representatives of the order Lepidoptera in the forest biocenosis, studies were carried out using several preparations affecting entomophages. The research showed that entomophages exhibit low sensitivity to various types of insecticides during their pre-imaginal development stages, i.e., at the larval and pupal phases. These studies represent a continuation of the scientific research conducted in 2021–2023, while the obtained results were simultaneously implemented in the forest management practices of the Tashkent region.
