白僵菌(Beanveria bassiana(Bals)Vaill)是一种半知菌类的虫生真菌,世界各大洲都有分布。我国已在9目34科200多种昆虫虫体上发现过白僵菌的寄生。70年代初,我们就开始了白僵菌粉防治马尾松毛虫的工作。白僵菌是一种比较理想的生物杀虫剂,能有效地抑制森林害虫的暴发。但是,由于白僵菌原粉体积大,不便于运输、贮存和使用。而且,施放出的菌粉仍有30%左右的菌孢子吸附在培养基上,不能充分利用。因而,使自僵菌在防治工作中,作为一种主要杀虫剂受到了限制。为了解决这一实际问题,1986年我们在湖北省林业厅、
Beanveria bassiana (Bals) Vaill is a fungous entomogenous fungus that is distributed on all continents. China has been parasitic on Beauveria bassiana in 9 orders, 34 families and more than 200 species of insect worms. In the early 70s, we started the work of Beauveria bassiana powder against Dendrolimus punctatus. Beauveria bassiana is an ideal biological pesticide, which can effectively inhibit the outbreak of forest pests. However, due to its large volume, the original powder of Beauveria bassiana is inconvenient to transport, store and use. In addition, about 30% of the bacterial spores released from the bacteria still adsorb on the medium and can not be fully utilized. Therefore, the autotrophic bacteria in the prevention and control work, as a major pesticide has been limited. In order to solve this practical problem, in 1986 we at the Department of Forestry in Hubei Province,
