Useful insects on Galega orientalis seed-plots in the Vologda region

The species composition of useful insects was determined during the years of the research on Galega orientalis seed-plots on soddy weak podzolic soil. They belong to the families of Ground beetles, Coccinellidae, Nabis, Lacewings and Malachius. The high efficiency of useful insects was determined at the optimum ratio predator-prey 1:2 and 1:3 - 95-98%.
