Entomopathogenic bacterium bacillus thuringiensis for microbial pest control
Research on entomopathogenic bacterium Bacillus thuringiensis and related microbial species with specific toxins and virulence factors for agricultural pest control. The bacterium produces toxic parasporal crystal proteins that serve as a biopesticide, offering a biological alternative to chemical pesticides.
Overview
This research focuses on entomopathogenic bacterium Bacillus thuringiensis and related microbial species as biopesticides for agricultural pest control. B. thuringiensis is an important microbial biopesticide that controls agricultural pests through the production of toxic parasporal crystal proteins. The research aims to identify new microbial species and strains with specific toxins and virulence factors that can expand the range of pests controlled and improve effectiveness. Bacterial entomopathogens under investigation include several Bacillaceae, Serratia, Pseudomonas, Yersinia, Burkholderia, Chromobacterium, Streptomyces, and Saccharopolyspora species. Complementary fungal entomopathogens include strains of Beauveria bassiana, Beauveria brongniartii, Metarhizium anisopliae, Verticillium, Lecanicillium, Hirsutella, Paecilomyces, and Isaria species. Together, these biological control agents offer sustainable alternatives to synthetic chemical pesticides.
