概要 Previous studies have indicated that female lifespan and egg production in some dipteran species decrease as an increasnig function of the body size of their mates. The purpose of our study was to det...ermine whether females of the stone leek leafminer Liliomyza chinensis were harmed by their mates through copulation. We tested the effects of male-size on female longevity, feeding and fecundity by mating small, middle and large males to medium-sized females. Females mated with larger males had no significant lower lifetime feeding and fecundity. Also male size had no significant effect on female longevity. Small males lived shorter than large males did. Our results indicate that male size does not affect female fitness. Meanwhile, small males had a lower reproductive success because of a decreased change of finding their mates.続きを見る
