Aphelinus asychis

Description

Aphelinus asychis is a parasitoid wasp native to Eurasia that was introduced to North America to control the Russian wheat aphid. Recent work shows that the species as currently described does not form a monophyletic group and its taxonomy and phylogenetic relationship should be re-examined. Aphelinus is a genus of parasitoid wasps. Several of the species are important because they parasitize agricultural pests, such as the soybean aphid (Aphis glycines) or the Russian wheat aphid -Diuraphis noxia - (A. albipodus Hayat & Fatima, A. asychis Walker, and A. varipes (Foerster). About 100 species have been described.
