Abstract

3-Hydroxysteroid oxidase in combination with Bacillus thuringiensis CryIA(b) or CryIA(c) crystal proteins or polypeptides controls insects, particularly lepidopterans. The combination when applied to larvae of several lepidopterans indicated significant effects on mortality and stunting and indicated responses that were statistically significant over those expected from additive, independent action. Cholesterol oxidase and CryIA(b) crystal protein were also effective against black cutworm neonates when co-expressed in transgenic corn and tested in a detached leaf assay.
