Depressed flour beetle: sensitivity to gamma irradiation
Ten krad of gamma irradiation to eggs and larvae of Palorus subdepressus (Wollaston) prevented the development of adults. Exposure of pupae to 5, 10, 20, 30, or 50 krad (but not 100) allowed some emergence, but longevity was greatly reduced. Adults were resistant to sterilizing effects of the radiation compared with other species of stored-product beetles: 30 krad was not completely sterilizing to either males or females, but the dose did greatly reduce fecundity, and longevity was significantly reduced: none survived for 3 weeks after a 20-krad exposure. Adults and pupae of this species would require higher doses of irradiation for effective control than would most other stored-product Coleoptera. (auth)
