The peculiarities of pest breeding on the stairs of winter wheat sowing under the newest systems of agriculture in the Forest-Steppe of Ukraine are highlighted. The analysis of the effectiveness of modern monitoring of the pest complex under new winter wheat protection systems was carried out. The main ecological and biological features of the formation of the entomocomplex of winter wheat emergence are determined. Features of monitoring and control of harmful insect species on winter wheat crops in the Forest-Steppe of Ukraine are highlighted. The analysis of the effectiveness of modeling the number of harmful and useful species of insects on the resource-saving protection systems of winter wheat. Specific features of biology and ecology of pests of stems and root system of wheat winter in the region of research are specified. The features of the formation of the entomocomplex in agrocenoses vary according to certain indices, in particular, the numbers of soil and intestinal phytophages, taking into account the radius of their daily movement. For effective management of crop production, it is actual to determine the total need of pests in the diet with the actual population of species at different stages of ontogeny of cereals.
Application in the production of resource-saving models for calculating the dynamics of phytophages on crops of cereal crops by hydrothermal coefficient at different periods of plant and phytophagous development, which makes it possible to determine the quantitative changes of an individual entomocomplex on crops of grain crops in time and space. In modern systems of agriculture in the Forest-Steppe of Ukraine, the development and introduction of complex methods for controlling winter pests of winter wheat, which determines the expected loss of grain in the fields of crop rotation, is of great importance.
