A study on the relationship of the Anuraphidina and their aphidiid parasites in Europe (Homoptera: Aphidoidea: Hymenoptera: Aphidiidae).

Abstract

Aphids of the group Anuraphidina represent a natural group occurring in mesophilic and xerophilie kinds of habitat. Quite a number of anuraphidine species change the type of habitat by migration from primary to secondary host plants. The aphidiid parasites of the Anuraphidina are distinctly differentiated with regard to habitat, so that dioecious aphid species, which change the type of habitat (forest and steppe) by migration, are attacked by complexes of parasites that are typical of a given type of habitat. The given host species, therefore, is attacked by different parasite species depending on the habitat in which it occurs.
