Nemkov V.A. CHANGES IN THE FAUNA AND HARMFULNESS OF GRAIN BEETLES IN ORENBURG REGIONThe fauna of the grain beetles of Orenburg region have been changed in the last 50-60 years. The main harmful pest of the wheat seed has become grain beetles Anisoplia ausriaca Hbst. Its extension to the east is due to the expansion of wheat sown areas. The number and harmfulness of grain beetles has declined in recent years, and the zone of harmfulness has shifted to the northern and central regions, which can be explained by unfavorable weather conditions, namely of the climate aridization.Key words: fauna, grain beetles, changes, distribution, harmfulness, wheat, aridization, climate.
