The purpose of research is to increase the yield of green mass without the use of chemical plant protection products. Successful and stable development of field forage production is based on the perfect structure of crops of agricultural crops with a scientifically based share of the area occupied by forage plants with pro-tein and energy value, environmentally safe and conducive to the preservation and expansion of soil fertility reproduction. The production of a stable feed yield is limited by a number of factors, one of which is the damage caused by pests, which significantly reduce the productivity and quality of the feed. Field research was conducted in 2016-2017. In the fodder crop rotation of the research laboratory «Forages» of the De-partment of Crop Production and Agriculture of the FSBEI HE Samara State Agricultural Academy. The entomofauna of mixed sowings of fodder grasses was studied by mowing with an entomological net. In mixed crops of fodder grasses, a significant variety of blasts belonging to the orders of insects was record-ed: Orthoptera, Homoptera, Thysanoptera, Hemiptera, Hymenoptera, Coleoptera, Diptera. In all the studied agrocenoses of mixed forage grasses there were representatives of the orders of the Bedbugs, the Horse-cloth and the Diptera. They also provided a greater variety of species. In agrocenoses with the participation of a rump and a wheatgrass there was a little similar species composition of insects, despite the fact that both species are grassy. Greater similarity of mixed crops of fodder grasses, and accordingly a higher Jac-quard coefficient was noted in three-component plant formations with the participation of the leguminous constituent. Inclusion of leguminous components in grass crops promoted an increase in both blasts and entomophages, with more pronounced this was observed with the addition of alfalfa or sainfoin. In the ag-rocenosis, the greybeard + grass gray + lapwing, horny inclusion of the leguminous component promoted an increase in the number of entomophages, and consequently a decrease in the damageability of crops by blasts.
