Abstract

The mating competitiveness of P1 and F1 generations of A. ipsilon when irradiated as full-grown pupae with 75 and 150 Gy of gamma irradiation was evaluated. The mating competitiveness values showed that either males or females of P1 or F1 generation were full competitive after treatment with 75 or 150 y at all released ratios. Mating competitiveness of both irradiated males and females was also studied to avoid problems concerning mass sexing. The results revealed that confining both sexes together gave excellent results for population suppression in both P1 and F1 in both tested doses and ratios. The addition of irradiated females to the release ratio make these females encountered in mating with untreated females, and possessed 78% of all matings occurred in parent generation in the two tested doses at 5:5:1 ratio and increased to reach 88% by F1 females 75 Gy while it was reduced to only 31% at 150 Gy, but still act in mating.
