Survival over the winter of Rhyzopertha dominica F. (Coleoptera: Bostrichidae) in hot spots caused by improper grain storage technology: the first record in the Czech Republic

Abstract

The survival of dense populations of Rhyzopertha dominica in stored grain hot spots in the Czech Republic during winter months was documented for the first time. Improper storage of grain causes subsurface hot zones, which seem to provide conditions for pest overwintering and become the source of subsequent cross infestations.
