Advances on High Performance Insecticide of Bacillus thuringiensis

Abstract:

Bacillus thuringiensis is one of the most effective and the most widely used microbial insecticides at present. The approaches to the strategy for high performance insecticide such as selective preference strain, constructive genetic engineering bacteria, mutagenesis screening and directed evolution are reviewed in this paper. Moreover, the advancement and the application prospects in high performance insecticide are discussed.

Key words:Bacillus thuringiensis, Selective preference strain, Constructive genetic engineering bacteria, Mutagenesis screening, Directed evolution, Insecticide strategy
