Abstract
Field estimates of parental investment in the two sexes in the social paper wasp Polistes fuscatus indicate that the mother's interests, rather than those of her worker offspring, are realized. Local competition for mates seemed to be absent, and the population investment ratio was not significantly different from 1:1. Workers are not more closely related to the brood they tend than they would be to their own offspring. The 3/4 relationship between sisters in haplodiploid species cannot account for the maintenance of eusociality in this case.This publication has 13 references indexed in Scilit:
