Seventeen strains of Bacillus thuringiensis were assayed against larvae of the noctuid Heliothis armigera [Helicoverpa armigera]. Generally, strains producing CryIA(c) were more toxic than those producing CryIA(b), IA(a), IB, IC and ID. There were differences in the toxicities of strains producing CryIA(c), with B. thuringiensis subsp. kurstaki HD-73 being the most toxic.
