Abstract
Two Dermestid beetles, Trogoderma granarium Everts and T. versicolor (Creutz.) have been recorded on a variety of stored products. In England, T. granarium is 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.
