Cross-resistance to Bacillus thuringiensis toxin CryIF in the diamondback moth (Plutella xylostella)
Applied and Environmental Microbiology 60 (12), 4627-4629
Abstract: Selection with Bacillus thuringiensis subsp. kurstaki, which contains CryIA and CryII toxins, caused a >200-fold cross-resistance to CryIF toxin from B. thuringiensis subsp. aizawai in the diamondback moth, Plutella xylostella. CryIE was not toxic, but CryIB was highly toxic to both selected and unselected larvae. The results show that extremely high levels of cross-resistance can be conferred across classes of CryI toxins of B. thuringiensis.
