The peculiarities of the ecology of individual pest species that reproduce in field crop rotations are highlighted, the indicators of the influence of environmental factors on the development and mass reproduction of insects in time and space in modern farming systems are generalized. Species composition of phytophagous insects of agrobiocenosis of winter wheat in the Forest-steppe of Ukraine is specified. A close relationship between the level of productivity and heat supply of plants and the main pests of phytophages is established. Optimal sowing time and temperature criteria of the autumn period are determined, which ensure the formation of maximum yields. Analysis of the distribution and harmfulness of the population of phytophagous insects in modern agrocenoses with forecasts and monitoring of the phytosanitary condition of winter wheat and other grain crops in the ForestSteppe of Ukraine is extremely topical with the current development of Ukraine's agriculture.
