Bacillus thuringiensis (Bt) is a bacterium widely used in biological control of pests. Bt biopesticides are considered important tools for combating agricultural pests due to their ability to produce crystalline proteins with insecticidal activity. Compared with traditional chemical pesticides, Bt biopesticides have higher specificity and are mainly targeted at specific pest groups, while having less impact on humans and other non-target organisms. The widespread use of chemical pesticides has not only led to the increase of pest resistance, but also caused serious impacts on the environment and human health. Therefore, the development and optimization of Bt biopesticides can not only reduce the use of chemicals, but also help maintain ecological balance and improve the quality and yield of crops. This study comprehensively analyzes the production technology, genetic engineering improvement methods, and application strategies of Bt biopesticides to improve their efficiency and application range. By exploring the fermentation process, formulation stability, industrial production, and strain enhancement characteristics of Bt biopesticides through genetic engineering, this study aims to provide a comprehensive improvement plan to provide a scientific basis for future research directions and policy formulation.
