Polydnavirus is a symbiotic virus of some endoparasitic wasps and plays crucial roles in inhibiting immune responses and retarding development of the parasitized hosts. Cotesia plutellae bracovirus (CpBV) is a polydnavirus suggesting a major causative to change developmental physiology of the parasitized host. Here, we investigated whether CpBV can interrupt development of non-natural host. Beet armyworm, Spodoptera exigua, is used as a non-permissible host for parasitization of C. plutellae. Extract from the calyx region of C. plutellae contained CpBV, which was confirmed by immunoblotting with a polyclonal antibody raised against CpBV.
