Beauveria bassiana is a broad-spectrum insecticidal fungus. Researchers at home and abroad use Beauveria bassiana to control corn borer, pine caterpillar, small cane borer, blind stink, corn weevil, citrus red spider, aphids and other agricultural and forestry pests. In particular, the biological control of corn borer and pine caterpillar has been used as a conventional method in China for years. Because beauveria bassiana can effectively control the population of insects without harming other natural enemies, insects and beneficial organisms, it is fully in line with the purpose of integrated pest management. At the same time, because it is easy to mass produce and its control cost is more competitive, it has a wide range of application prospects.
