Abstract
Bacillus thuringiensis (Bt), renowned for its potential, rapid action and environmental sustainability, remains an understudied group, particularly in newly identified strains. In this study, we screened a novel Bt strain, HSY204, extracted from soil samples. Our results revealed that HSY204 belonged to a new species of Bt with remarkable efficacy against Aedes aegypti larvae. The complete HSY204 genome analysis revealed nine toxin genes. In particular, a protein similar to Xpp37Aa showed very promising effectiveness in mosquito suppression, though surpassed by Bacillus thuringiensis subsp. israelensis (Bti). This research provides a valuable background for future biotechnological applications of HSY204 strain as a basis for the production of commercial bioinsecticides, thereby contributing to the development of innovative and environmentally friendly bioinsecticide strategies.
期刊介绍:
Pesticide Biochemistry and Physiology publishes original scientific articles pertaining to the mode of action of plant protection agents such as insecticides, fungicides, herbicides, and similar compounds, including nonlethal pest control agents, biosynthesis of pheromones, hormones, and plant resistance agents. Manuscripts may include a biochemical, physiological, or molecular study for an understanding of comparative toxicology or selective toxicity of both target and nontarget organisms. Particular interest will be given to studies on the molecular biology of pest control, toxicology, and pesticide resistance.
Research Areas Emphasized Include the Biochemistry and Physiology of:
• Comparative toxicity
• Mode of action
• Pathophysiology
• Plant growth regulators
• Resistance
• Other effects of pesticides on both parasites and hosts.
