It can be prepared as a fungal insecticide to control pests in agriculture and forestry and used for the artificial production of the Chinese medicinal material Bombyx Batryticatus. Here we introduced the biological characteristics, infection characteristics, application status, and shortcomings of B. bassiana and put forward the development countermeasures, aiming to provide reference for further development and application of B. bassiana.
