Among 64 parasitoid wasp species, life-span is negatively correlated with ovigeny index (controlling for phylogeny), in accordance with general life-history theory which predicts a reduction in longevity with increased reproductive effort (Jervis et al.2001) The Ovigeny index is the proportion of the lifetime of the potential egg complement that is ready for laying when the female emerges (Jervis&Ferns 2004).
Schematic representation of the empirical relationships between initial egg load, lifetime potential fecundity and body size, (A) within and (B) between parasitoid wasp species. Ovigeny index declines with increasing body size both intraspecifically and interspecifically, in accordance with:
(i) the predictions of theoretical models developed for parasitoids (Ellers & Jervis, 2003) and
(ii) the predictions of general life-history theory regarding the change in reproductive effort relative to adult biomass in insects generally (Reiss, 1989).
