Aphelinus certus

Description

Aphelinus certus is a parasitoid wasp native to Asia. It parasitizes the soybean aphid and other aphids. A. certus has been found in North America since 2005, and was likely introduced along with or soon after the soybean aphid. A. certus is likely to parasitize both native and introduced aphids in North America as it has a relatively wide host-range. 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.
