About species composition and diversity of major consumers in potato agrobiogeocenosis of Bryanskaya oblast'

On basis of long-term entomological observation the authors estimated the diversity of species composition of major consumers and the structure of consumer cenosis in connection with agroclimatic character of region. The studied ecotopes distinguished by geographical location, hydrological and soil conditions, by type of rotation of crops and varietal features of producer. The agrobiogeocenosis of forest agroclimatic region had the maximal species diversity, but the residential areas - the minimal one.
