Sažetak

Presence of harmful insects and mites is almost inevitable in mercantile wheat stored in warehouses. They cause significant damages and therefore it is necessary to perform pest control and chemical treatment. Study of harmful and destructive entomophauna impacts on quality of mercantile wheat and flour has been presented. Mercantile wheat stored in silos has been used in the study. Testing of quality of rheological properties and presence of harmful entomophauna were done in the labs within the silos «Žitoprerada d.o.o. Valpovo « and Department of Plant Protection on Faculty of Agriculture in Osijek. Presence of harmful entomophauna, quality of mercantile wheat stored in a warehouse and rheological flour properties were determined.
The following harmful entomophauna were found: mites (Acarinae), primary pests of order Coleoptera and Lepidoptera, secondary pests of order Coleoptera and other insects found belong to Coleoptera, Psocoptera and useful insects of Hymenoptera orders. Influence of harmful entomophauna on quality of mercantile wheat is manifested by reduced quality of stored wheat due to decrease of water content and hectoliter mass. Lower quality of flour obtained by milling of infected wheat is manifested by change in rheological properties: dough stability, water absorption, growth, resistance, energy, extensibility, maximum resistance, start of puffing up, and viscosity.
