寄生蜂アオムシヒラタヒメバチにおける過寄生が蜂の羽化率と性比に与える影響

抄録

Superparasitism and sex allocation in parasitized hosts in Itoplectis naranyae and the effects of superparasitism on offspring survival and sex ratio at wasp emergence were studied. Female wasps accepted the majority of parasitized hosts for oviposition and did not change sex allocation in response to them. There is no significant difference in the percentage of wasp emergence between singly and plurally parasitized hosts. Superparatisitism did not influence sex ratio at wasp emergence.
