Technical Bulletin No. 1228
For several years members of the dermestid beetle genus Trogoderma have attracted widespread attention, particularly since T. granariurn Everts, the khapra beetle, became established as an introduced pest in Arizona, California, Mexico, and New Mexico. This species has been the object of a control program to remove it as a hazard to stored grain and to prevent its spread to parts of the country where it is not known to occur. Species of Trogoderma other than the khapra beetle may also build up to damaging numbers in stored products. Information has been obtained on these species, as well as on granariurn, during the course of these studies.
