Abstract: Parasitoid wasps are currently hot subjects for the study of sex allocation. The sex determination of these wasps is haplodiploid. Unfertilized haploid eggs develop into males, and fertilized diploid eggs develop into females. Because of factors such as local mate competition and inbreeding a female-biased sex ratio is the evolutionary stable strategy in those wasps. Founder females can adjust the sex ratio of their offspring according to environmental conditions in order to obtain the highest fitness benefits. The theory of local mate
