The lifetime fecundity and hatch rate of parental adults and the number of adult offspring/moth were the lowest when the sex ratio was 3:1, while the lifetime fecundity and number of adult offspring/moth were the highest and pupation duration was the shortest when the sex ratio was 1:1. The number of eggs/moth of parental adults and total adults in the F1 generation were higher in male-biased groups than in female-biased groups, and male annihilation appears to be a more effective control strategy.
