Protection of grain from the storage pests
The article presents the results of granaries arthropod fauna studies for 2002-2014 in Belarus. Based on the study of species composition, it was established that in the structure of dominance, the largest proportion was mites: in unloaded warehouses - up to 55 %, in loaded - up to 94 %. For the first time, acarindexes were calculated, which allow predicting the increase in the number and severity of mites in batches of barley, oats and wheat. Taking into account the species composition of pests, the structure of dominance, various methods of processing storage facilities and grain, the appointment of grain storage facilities and stored products, the protection system has been improved, which allows obtaining biological efficiency up to 100% and preserving grain resources. The expediency of systematic storage pests monitoring of stocks in connection with climate warming, as well as control over the state of arthropod populations for resistance to insecticides and insectiсacaricides, is indicated.
