Summary
The ability ofDrosophila melanogaster larvae in Europe to encapsulate the eggs of their most important parasitoids,Asobara tabida andLeptopilina boulardi, shows a large amount of geographical variation. Interestingly, encapsulation ability againstA. tabida is not correlated with encapsulation ability againstL. boulardi. This indicates that the encapsulation system ofD. melanogaster larvae has parasitoid-specific components. The variation in encapsulation ability can only partly be explained by the incidence of parasitism on the larvae. This means that factors other than the two parasitoid species must be selection pressures on the encapsulation ability ofD. melanogaster larvae.
