AbstractParasitoids are significant enemies of many economically important insects and there is some evidence to suggest that their actions have a role in terminating the outbreaks of forest Lepidoptera populations. In this study, we examined the impact of parasitoids on the pupae of the pine processionary moth, and highlighted the presence of several parasitoid species for this developmental stage. A higher rate of parasitism was found when the pupal density in the soil was reduced, but the rate of parasitism was not influenced by pupal morphological traits or by the presence or absence of a cocoon around a pupa. Of the external factors examined, a delay in the time of descent of larvae from the trees had a positive effect on the level of parasitism. Observational data indicated that dipteran and hymenopteran were the most abundant parasitoids to emerge from moth pupae. Our study highlights the complexity of the parasitoid–host dynamics, and stresses the importance of carefully determining environmental effects on host–parasitoid relations.

Abundance, variability, and aggregation of larval populations of 162 species of lepidoptera, feeding on the foliage of primarily deciduous trees in southern Ontario, were analyzed to test four hypotheses about the relationship of species to their resources. The lepidoptera larvae were treated both as exploiters of foliage and as resources for parasitoids. Multiple regression and partial correlation analysis revealed that (1) the abundance and variability of a moth population were independent of the diversity of host trees fed upon, (2) the incidence of parasitism on a moth population was independent of the variability of the host population, and (3) the diversity of parasites of a moth was independent of the variability of the host population. We raise the possibility that parasites may be ineffective control agents for lepidoptera species.
