Abstrakt: The expediency of taking into account the potential of the entomocomplex in the integrated management of agricultural plant and the whole agroecosystem protection on the basis of synecology and sustainable nature managment is substantiated. The experiments were performed at an organic research station (Kyiv region, Ukraine). The peculiarities of the structure and dynamics of the taxonomic composition of entomofauna and biodiversity indexes during the vegetation period of organic soybean development in comparison with the conventional one, as well as in the adjacent forest shelter belts, were studied in 3 years. Larger numbers and diversity of insects have been observed in organic fields. The values of insect diversity indexes were higher in forest belts than in soybean crops, regardless of the technology of its cultivation. According to the Sorensen index, the taxonomic structure of insects in organic fields and adjacent forest belts is more similar than that in organic and conventional fields. However, a larger proportion of phytophages has been recorded in organic fields. [ABSTRACT FROM AUTHOR]
