Aphelinus certus

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.
