Abstract

In this study, gamma radiation was applied at six dose levels over the range of 5-40 Gy for 0-2-day-old eggs, and at eight dose levels between 10-80 Gy for 16-18-day-old larvae of Tribolium confusum. Sterility, mortality and other effects of gamma radiation were investigated, All experiments were performed in incubators maintained at 27 +/- 0.5 degrees C and 70 +/- 5% r.h. The development of adults reared on different flours from irradiated eggs and larvae was prevented by exposure to 40 and 50 Gy of gamma radiation, respectively, Rate of development of these stages on different flours and the yield of adults was influenced by rearing medium, Rapidly developing flour beetles are more susceptible to killing by gamma radiation, For each stage reared on different media (wheat, barley and maize flours), LD(50) and LD(99.9) values were determined, together with sterilizing dose levels (SD50 and SD99.9).
