Genetics of Pink Bollworm Resistance to Bacillus thuringiensis Toxin Cry1Ac (2001)
Yong-Biao Liu, Bruce E. Tabashnik, Susan K. Meyer, Yves Carrière, Alan C. Bartlett
Laboratory selection increased resistance of pink bollworm (Pectinophora gossypiella) to the Bacillus thuringiensis toxin Cry1Ac. Three selections with Cry1Ac in artificial diet increased resistance...

We studied mechanisms of resistance to Bacillus thuringiensis insecticidal crystal protein Cry1C in the diamondback moth, Plutella xylostella (L.). Binding assays with midgut brush border membrane...
Heckel, David G., Gahan, Linda J., Liu, Yong-Biao, Tabashnik, Bruce E.
Transgenic plants producing environmentally benign Bacillus thuringiensis (Bt) toxins are deployed increasingly for insect control, but their efficacy will be short-lived if pests adapt quickly. The...
One gene in diamondback moth confers resistance to four Bacillus thuringiensis toxins
Tabashnik, Bruce E., Liu, Yong-Biao, Finson, Naomi, Masson, Luke, Heckel, David G.
Environmentally benign insecticides derived from the soil bacterium Bacillus thuringiensis (Bt) are the most widely used biopesticides, but their success will be short-lived if pests quickly adapt to...
