Hymenoptera of the Asobara genus are endophagous parasitoids of Drosophila larvae. In these apocrita insects whose venom gland is associated with the female reproductive tract, the wasp venom is injected into the host along with the parasitoid egg during oviposition. We conducted a comparative study of the venom apparatuses from three Asobara spp.: the European Asobara tabida, the Asiatic A. japonica and the African A. citri. Light and electron microscopy of venom glands, together with the biochemical analysis of their contents, revealed important differences between Asobara spp. In addition, the physiological effects of female wasp's venom injected into Drosophila larvae differed greatly between the tested Asobara spp.
