苏云金杆菌(Bacillus thuringiensis)分布广泛。过去,许多研究者不但从死亡昆虫中分离获得大量对鳞翅目害虫有毒的菌株。而且还获得了对双翅目害虫等有效的菌株。自1970年以来,天门县微生物研究所、武汉病毒研究所等单位先后从自然死亡的昆虫体内分离到7216、140、荆菌2号、82612等苏云金杆菌菌株,并在防治农林果蔬害虫方面得到了广泛的应用。为了充分挖掘我省微生物资源,作者从1972年开始,在全省有代表 Bacillus thuringiensis is widely distributed. In the past, many researchers have not only isolated a large number of strains that are toxic to Lepidopteran pests from dead insects. But also obtained effective against dipterous pests and other strains. Since 1970, Tianmen Microbial Research Institute and Wuhan Institute of Virology have successively isolated Bacillus thuringiensis strains 7216,140, ​​Jingjian 2 and 82612 from insects that died naturally and got the control of pests of fruits and vegetables in agriculture and forestry Wide range of applications. In order to fully tap the province’s microbial resources, the author from 1972 onwards, represented in the province
