Effect of X-ray Irradiation on Development, Flight, and Reproduction of

is an omnivorous pest that has spread globally. Because irradiation sterilization technology has a great potential for control of , the effect of 25-150 Gy doses of X-rays on pupal survival, flight and reproductive variables of adult moths were analyzed in this research. The X-ray irradiation with the dose of 25-150 Gy significantly affected the reproductive ability of females. Irradiating male pupae with 25-150 Gy doses of X-rays had no effect on mating, life span, or flight ability of adult moths, but significantly reduced survival and fecundity of their offspring, and the sterility rate of the F generation was 52.65%-99.9%. The results of logistic curve fitting showed that the sterility impact was 84% at the most appropriate irradiation dose (71.26 Gy). The sterility control was 91% in an indoor mating competition experiment when the release ratio of irradiated males (75 Gy) to nonirradiated males reached 12.6:1. The effects of X-ray irradiation doses on biological variables of and the most effective release ratio determined here provide a theoretical foundation for using radiation sterilization technology to control .
