【Abstract】 Normal female corn borer moths, when mated with male moths irradiated with a partial sterilizing dose （20 to 25 KR ）, produced R₁ larvae with delayed development, increased mortality, distorted sex ratio, and even almost fully sterilized offsprings. When the same dose was used to irradiate female moths, fully or nearly fully sterilization was produced.The competitiveness of irradiated males to normal males, when released together with irradiated females, did not decrease as compared with releasing the males alone. This indicates the possibility of releasing both sexes of irradiated moths in practice.However, the surviving R₂ , although very few in number, recovered their fertility quickly, and became almost normal in R₃.更多还原
