CABI Book Chapter Info
Cover for Different models of the mode of action of Bt 3d-Cry toxins.

Bacillus thuringiensis (Bt) produces insecticidal proteins that are active against different insect orders. In particular, the family of the three domain-Cry toxins (3d-Cry) have important applications in controlling insect pests as spray products or in transgenic Bt plants. At least three...

Cover for The development and prospect of discovery of Bt toxin genes.

Bacillus thuringiensis (Bt) Cry protein-based insect control has proven to be effective in reducing the use of chemical insecticides and in increasing crop yields. However, Bt crops increase selection pressure for resistant insects and accelerate their succession. The discovery and application of...

Cover for RNA interference strategy for crop protection against insect pests.

RNA interference (RNAi) has significantly accelerated functional genomic research on insects. Since its discovery, numerous reports have reported efforts to apply RNAi approaches to insect species lacking characterized genomes. The technique also has substantial potential for use in the control of...

Cover for Countering pest resistance with genetically modified Bt toxins.

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...

Cover for Status of resistance to Bt cotton in China: cotton bollworm and pink bollworm.

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...

Cover for Roles of insect midgut cadherin in Bt intoxication and resistance.

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...

Cover for Resistance of cabbage loopers to Btk in a greenhouse setting: occurrence, spread and management.

Resistance to the microbial insecticide Btk occurred in a number of laboratory populations of Lepidoptera before it was discovered in field populations. Therefore, it is not surprising that cabbage loopers (Trichoplusia ni) in semi-contained vegetable greenhouses were among the first examples of...

Cover for Mechanism of Cry1Ac resistance in cabbage loopers - a resistance mechanism selected in insect populations in an agricultural environment.

The development of resistance to Bacillus thuringiensis (Bt) in insect populations in agriculture not only depends on the level of resistance conferred by a selected resistance mechanism, but also on the fitness cost associated with the resistance mechanism under specific ecological and...
