“7216”杀虫菌是湖北省天门县微生物研究所从自然死亡的越冬红铃虫体中分离出来的一株繁殖快、晶体大、血清型为H_(3a3b)的苏云杆菌新变种,对菜青虫、小菜蛾有较好的致死力。 1983年9月菜青虫高峰期,在西郊公社三大队二队三组的莲花白上进行了“7216”菌药的防治试验,结果证明“7216”菌药具有保护天敌、无公害的作用,是进行生物防治的一条重要途径。
“7216” is a new strain of Bacillus thuringiensis that breeds fast, large crystal and serotype H_ (3a3b) isolated from naturally died red bollworm body in Tianmen County Microbial Institute of Hubei Province.

September 1983 cabbage peak, in the western suburbs of the three brigade two teams of three groups of lotus white on the “7216” prevention and control of fungi, the results show that “7216” has the protection of natural enemies of bacteria, pollution-free effect, It is an important way to carry out biological control.
