“灭蛾灵”即苏云金杆菌血清3型H_3—6—11的一种菌株。它的致死机理主要是在害虫取食的过程中,菌体随植物叶组织经口进入害虫体内,在里面分裂繁殖,先破坏中肠肠壁的上皮细胞,并使之与肠壁脱离,由此引起食欲不振,表现拒食现象。细菌在中肠附近繁殖很快,最后穿孔进入血腔,这时伴孢晶体的毒源也在其中 “Kill the moth,” a strain of Bacillus thuringiensis serotype 3 H_3-6-11. Its lethal mechanism is mainly in the pest feeding process, the bacteria with the plant leaf tissue into the pest through the mouth, which split propagation, the first destruction of epithelial cells in the intestinal wall, and make it detached from the intestinal wall by This caused loss of appetite, the performance of anti-feeding phenomenon. Bacteria multiply rapidly in the midgut, and finally perforation into the bloodstream, when the source of the sporozoite crystals are also among them
