On-plant survival and inheritance of resistance to Cry1Ab toxin fromBacillus thuringiensisin a field-derived strain of European corn borer,Ostrinia nubilalis

BACKGROUND: The high dose plus refuge is one of the major components of the resistance management plan mandated for transgenic corn expressing Cry toxins from Bacillus thuringiensis Berliner ( Bt ) that targets the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). This strategy was based on assumptions such as functional recessive inheritance, which has not been previously tested for O. nubilalis . The authors used a...
