Abstract

Abstract The development of adult Tribolium destructor Uyttenboogaart from eggs and larvae was prevented by exposing these immature stages to 5 krad of gamma irradiation. However, some adults did emerge when pupae were exposed to 5–30 krad. Adult longevity was significantly reduced, and sterility of both sexes was effected by doses of 10 krad and above. Control of this species therefore appears feasible with the levels of irradiation currently approved by the U.S. Food and Drug Administration (20–50 krad) for treatment of stored-grain insects in wheat and wheat flour in the U.S.
