The Drosophila parasitoid Asobara japonica Belokobylskij (Hymenoptera: Braconidae) has highly toxic venom that kills host larvae if its injection is not followed by an injection of lateral oviduct components along with egg-laying. In the present study, the venoms of seven other Drosophila parasitoids (Asobara rossica, Asobara rufescens, Asobara pleuralis, Leptopilina heterotoma, Leptopilina japonica, Leptopilina ryukyuensis, and Leptopilina victoriae) are tested against three kinds of Drosophila species (i.e. Drosophila species that are suitable as host for focal parasitoids, those that are resistant to the parasitoids, and a cosmopolitan species, Drosophila simulans). Venoms of the three Asobara species are not toxic to any of Drosophila species, whereas those of the four Leptopilina species are toxic to some Drosophila species. The toxicity of venom varies among Leptopilina species, and the susceptibility to venom also varies among host Drosophila species. Furthermore, toxicity and paralytic effects of venom are not correlated. Because the toxicity of venom is not adaptive for parasitoids, it may be an inevitable side effect of some components that play an essential role in parasitism.
