Resistance of greenhouse-selected strains of the cabbage looper,Trichoplusia ni , toBacillus thuringiensis subsp.kurstaki was countered by a hybrid strain ofB. thuringiensis and genetically modified toxins Cry1AbMod and Cry1AcMod, which lack helix α-1. Resistance to Cry1AbMod and Cry1AcMod was >100-fold less than resistance to native toxins Cry1Ab and Cry1Ac.
