Microbial control and biotechnology research on Bacillus thuringiensis in China

The current status of production and application of biopesticides for pest control in China is briefly reviewed, with a focus on research advances in microbial control with Bacillus thuringiensis (Bt). These have led to improvements in Bt production, exploitation of Bt gene resources, and development of engineered Bt insecticides and transgenic Bt crops that have expanded host ranges and increased efficacy against target pests. Both conventional and biotechnology approaches need to be employed to achieve further progress in discovery, production technology, formulation processing, development of quality standards and recommended use patterns.
