The article highlights the features of reproduction, development and survival of Lepidoptera phytophages in field crop rotations using advanced monitoring technologies for these pests in the Forest-Steppe of Ukraine. Specific features of the biology and ecology of the scoops of winter Agrotis segetum Schiff. Are clarified. This belongs to the butterfly series – Lepidoptera, the scoop family – Noctuidae, on the rotation of sunflower and winter wheat in the regions of research. It has been established that the populations of the main species of lepidopteran pests that form during the vegetation period undergo cyclical fluctuations in the sum of effective temperatures, solar activity and geophysical indicators. Outbreaks of the number of winter shovels are repeated at various intervals, they are synchronized with the cycles of weather, climate, crop yields and solar activity, have both direct and indirect effects on the dynamics of the biosphere, agroecosystems and populations, they are inhabited It is characteristic that the sharp fluctuation of the weather turned out to be optimal for the development and distribution of these types of pests of the generative organs of winter wheat, sunflower and other cereal crops in the forest-steppe of Ukraine. It is known that the species composition and abundance of Agrotis segetum Schiff. in different years of growing crops, depending on the technology of their cultivation, weather and climatic conditions and the region - vary. Population polyphagae scoops inherent cyclic fluctuations in numbers, due to the internal population and other mechanisms. Refinement of the phenology of the pest depending on abiotic factors. Agrotis segetum Schiff winter scoop populations. inherent cyclical fluctuations in numbers, which are mainly due to the internal population mechanisms
