To study the mechanism of gamma-radiation in the male adults of the West Indian sweet potato weevil, Eusceps postfasciatus, the effects of gamma-radiation on spermatogenesis were examined histologically. In the irradiated adults, histological changes related to an inhibition of spermatogenesis were found by light-and electron-microscopic observations. The radiation conditions best suited to prevent a decline in the life-span of irradiated adults were discussed.
