在害虫病原微生物中,真菌致病的最多,占60％以上。而在530多种虫生真菌引起的昆虫真菌病中,由白僵菌引起的就占到21％。可见白僵菌是昆虫重要病原菌之一。白僵菌的寄主范围很广,现在已报道的有200多种昆虫及螨类。致病力也很强,一般室内杀虫试验都在70％以上。解放以来,我国各地广泛应用白僵菌防治农林害虫,效果良好。例如,防治松毛虫已遍及南方13个省(区),致死率达60-80％;防治玉米螟已发展到全国11个省(市),致死率达80％以
In the pest pathogenic microorganisms, the most fungal pathogenic, accounting for more than 60%. In more than 530 species of entomopathogenic fungi, Beauveria bassiana accounts for 21%. Beauveria bassiana is one of the important pathogens in insects. Beauveria bassiana host a wide range of now more than 200 kinds of insects and mites have been reported. Virulence is also very strong, indoor insecticide tests are generally more than 70%. Since liberation, Beauveria bassiana has been widely used throughout our country to prevent and control agricultural and forestry pests and has good effect. For example, the prevention and control of pine caterpillars has spread to 13 provinces (districts) in the south with a lethal rate of 60-80%. The prevention and control of corn borer has developed to 11 provinces (cities) nationwide with a lethal rate of 80%
