SUMMARY
Is investigated the role konsortive of adults beetle Kuzka (Anisoplia austriaca Hrbst. 1783) in the functioning of phytocenoses wheat soft, rye, triticale winter. Installed the amount, density and harmfulness of populations Anisoplia austriaca Hrbst. in the dynamics on different genotypes of grain of winter crops. By the probability of being ecological niche for imago Anisoplia austriaca Hrbst. genotypes of soft wheat, triticale and rye are differentiated into the following groups: weakly probable, probable and strongly probable ecological niches.
