The Biology of the Dermestid Beetles,Trogoderma granariumEverts andTrogoderma versicolor(Creutz.)

Abstract

Two Dermestid beetles,Trogoderma granariumEverts andT. versicolor(Creutz.) have been recorded on a variety of stored products. In England,T. granariumis a serious pest only in maltings. The life-history is described. The larvae are responsible for the damage to stored products, and their hairy nature facilitates the spread of infestations on sacking and clothing.All stages in the life-cycle are resistant to heat and dryness.
