Abstract
Populations ofTribolium castaneum(Herbst) exposed to sublethal doses of irradiation (0.5–4.0 krad) each generation for as many as 25 generations had decreases in reproductive capacity and increases in sterility that were positively correlated with the size of the dose per generation, but not with the number of ancestral generations treated. Exposure of the selected populations to an acute dose of irradiation (2.0 krad) revealed no increase in tolerance to irradiation even after 25 generations of selection. Radioresistant populations would probably not arise from fertile survivors of irradiation disinfestation of bulk grain.Keywords
