Chouioia cunea (Yang) (Hymenoptera: Eulophidae) is an indigenous pupal endoparasitoid that effectively attacks the exotic fall webworm Hyphantria cunea (Drury) (Lepidoptera: Arctiidae) in China. In this novel association, the parasitoid's venom has played an important role in subduing the immune defense of the host although little is known about the composition and functions of the parasitoid's venom. We therefore first identified the parasitoid's major venom proteins using electrospray ionization-mass spectrometry (ESI-MS). Approximately 207 different proteins were identified from C. cunea's venom; among them 26 types widely existed in other endoparasitoids' venom, including calreticulin and arginine kinase, which inhibited the host immune system.
