| Abstract | ||||
| The effect of gamma radiation on Tyrophagus putrescenriae (Schr.) was studied. The seven different doses were chosen to expose the adult stage 10, 20. 30.40.60.130 and100 Krad. Fecundity, egg viability, sterility, oviposition period duration and survival of mature stage. adult lifespan and sex ratio of F1 progeny as a result of adult stage were determined. Untreated females that were crossed with males exposed at doses 60. 30 krad lay only a few eggs duration the initial days of oviposition period stopped producing eggs. Hatchability of produced eggs also decreased with increasing the dose. A complete sterility of eggs occurred when the males and females were irradiated at 30 and 100 doses Kard, respectively. Females mated to irradiated males produced fewer females' progeny. Females exposed to radiation and mated to untreated males produced fewer males' progeny. respectively | ||||
