Abstract

Question: Does male size affect fitness in gregarious parasitoids? Hypothesis: Larger males achieve higher reproductive success by obtaining more matings when in a competitive scenario and by living longer. Although mating can be costly, larger males are better able to withstand these costs. Methods: Three experiments: two assessed the effect of size on mating success, one with and one without the presence of a competitor; the third experiment explored the relationship between male size and longevity under alternative mating regimes. Results: Mating success did not depend on male size even in the presence of an introduced competitor. Mating reduced male longevity, but it did so independently of size.
