Comparative susceptibility of Ostrinia furnacalis, Ostrinia nubilalis and Diatraea saccharalis (Lepidoptera: Crambidae) to Bacillus thuringiensis Cry1 toxins

► Two Ostrinia species were susceptible to a range of Bacillus thuringiensis toxins. ► A different pattern of susceptibility was observed for Diatrea saccharalis. ► Results suggest shared toxin receptors for the two Ostrinia species.
