This book focuses on descriptions of the extent of use of Bacillus thuringiensis (Bt) crops and the emerging problem of resistance, recent progress in elucidating the mechanism of action of Bt toxins and describing the different resistance mechanisms and strategies for coping with resistance in the ...

Transgenic cotton that expresses a gene derived from the bacterium Bacillus thuringiensis (Bt) has been deployed for combating the cotton pests Helicoverpa armigera and Pectinophora gossypiella since 1997 in China. The pest management tactics associated with Bt cotton have resulted in a drastic...

Genetically engineered crops producing Bacillus thuringiensis (Bt) proteins for insect control target major insect pests. Bt crops have improved yields and their use reduces the risks associated with the application of conventional insecticides. However, the evolution of resistance to Bt toxins by...

Farmers planted genetically engineered crops that produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) on a cumulative total of 570 million ha worldwide from 1996 to 2013. These Bt crops kill some key insect pests, yet they are not toxic to most other organisms, including...

Bioinsecticides based on Bacillus thuringiensis (Bt) and transgenic plants expressing its toxins have been widely used to control insects in Latin America. In Brazil, during the season of 2013/14, 4 million ha were treated with Bt biopesticides, and the area of transgenic crops under cultivation...

Insecticidal crystalline (Cry) toxins from the bacterium Bacillus thuringiensis (Bt) used in sprays and transgenic crop plants have provided major benefits for pest control, including decreased reliance on broad-spectrum chemical insecticides. However, extensive use of Bt toxins has selected for...
