| 摘 要： | 粘虫 Mythimna separata (Walker) 和小菜蛾Plutella xylostella L.的幼虫经斑蝥素处理后，中肠组织发生明显的病变。粘虫幼虫中肠柱状细胞微绒毛脱落，杯状细胞变大，质膜消失；线粒体不规则肿胀，内嵴排列紊乱、溶解、断裂；粗面内质网扩张明显，核糖体脱落；细胞核肿胀，染色质浓缩，偏移。小菜蛾幼虫中肠组织病变更为明显。表明斑蝥素主要作用于中肠的膜系统，为进一步探讨其毒理机制提供了理论依据。 |

| Abstract: | Obvious pathological changes in the midgut of the orient armyworm, Mythimna separata and the diamondback moth, Plutella xylostella were observed following treatment with cantharidin. The microvilli were sloughed off, goblet cell cavities enlarged, their projections sloughed off and the plasma membrane disappeared. Mitochondria swelled irregularly and their cristae fractured and become fuzzy. The cisternae of rough endoplasmic reticulum swelled obviously and the ribosomes denuded. The cell nucleus swelled and chromatin became concentrated. All the above observations show that cantharidin acts on the midgut membrane system. |
| Keywords: | cantharidin Mythimna separata Plutella xylostella midgut toxic mechanism |
