摘　　要：为了探讨苏芸金杆菌对鳞翅目昆虫的作用机理，笔者通过光学镜和电镜对苏芸金杆菌感染落叶松毛虫后的组织病理和细胞病理进行了研究，结果为感染初期松毛虫幼虫中肠柱状细胞的微绒毛受到破坏，继而中肠细胞开始出现空洞，感染４２ｈ后中肠上皮细胞完全从基低膜上脱落。The histopathology and cell pathology of Dendrolimus superans infested by Bacillus thuringiensis were studied by means of optical instrument and electron microscope in order to know the effection mechanism of Bt to Lepidoptera insects. The microvillus of midgut pillar cells were damaged in the beginning of infection, then cavitiea appeared on the midgut cells, and epiderm cells of midgut fell off from the base membrane after 42 h.
