Qualitative Analysis of Aphid and Primary Parasitoid Trophic Relations of Genus <I>Alloxysta</I> (Hymenoptera: Cynipoidea: Figitidae: Charipinae)

Charipinae hyperparasitoids affect effectiveness of the primary parasitoids of aphids by decreasing their abundance and modifying their behavior. As a result, increase of aphid populations can cause severe yield losses in some crops. Therefore, ecological studies on the subfamily Charipinae have a great economical and biological importance. Host specificity of these hyperparasitoids is still under debate and for many Charipinae species very little is known about their trophic relations. Here, we give a comprehensive overview of the trophic relationships between the Charipinae species of the genus Alloxysta Forster and their aphid and primary parasitoids hosts, worldwide. Within this subfami…
