Five populations of Callosobruchus maculatus (F.) were treated, respectively, with 0 (control), 05, 1, 2, or 4 krad of gamma radiation for 7 successive generations. Croups of 7th-generation adults were tested for resistance to acute irradiation by exposure to total doses of 16 and 50 krad. Un irradiated 8th-generation adults from each population were checked for mating success and fecundity.

When longevity was checked after acute radiation exposures, no evidence of increased resistance to acute radiation exposures was found. Irradiated populations showed slight but not significant decreases in mean survival time. A reduction in fecundity in the irradiated populations indicated also a decrease in population fitness. Therefore the possibility of development of radiation-resistant insect strains by accidental exposure of some insects to sbsterilizing dosages during commercial radiation disinfestation docs not appear to be a problem.
