Abstract

Small females of the parasite Nasonia vitripennis (Walk.) parasitized fewer hosts (housefly, Musca domestica L.) than larger ones during their lifetime because they had both a shorter life span and a lower rate of parasitization. The latter resulted primarily from a lower egg maturation rate. As females reared from superparasitized hosts are on the average smaller than those reared from non-superparasitized ones, these effects of parasite size reduce the rate of increase of N. vitripennis at high parasite:host ratios and result in greater stability in the interaction between the two species.
