| Summary: | Numerous arthropods have adapted to live in various biocenosis in the process of evolutionary transformation, especially under the influence of anthropogenic pressure, in particular cotton, which is widely distributed in Uzbekistan, especially in the lower reaches of the Zarafshan river. Among them there is a large group of phytophages, which causes substantial harm to cotton. It is also home to predatory and parasitic insects, entomophages, which are their effective regulators. The long-term impact of the anthropic factor on the complex of phytophages and entomophages in cotton agrobiocenosis could not but affect their vital activity. Meanwhile, previous studies did not fully open the nature of interaction of individual groups of arthropod animals and did not take into account the changes that occurred in the transformed natural environment. The aim of the research is to study the species composition of arthropods, to determine the main species of phytophages and entomophages, their ecology and biological principles for regulating their numbers in cotton agrobiocenosis.
