| 摘 要： | 通过光学显微镜及电子显微镜观察，综合分析了昆虫生长调节剂卡死克对东亚飞蝗表皮与脑的显微及亚显微形态结构的影响。结果表明，处理后的若虫表皮由于真皮细胞结构被破坏导致内表皮变薄、板层结构消失，而且真皮细胞层与内表皮层分离，细胞质内小泡变大而分布不均，核染色质凝结成为小颗粒且分布不匀。脑神经分泌细胞受药物影响数量明显减少，结构松散，胞间空泡变大，引起轴突变形。经透射电子显微镜检查发现，脑神经分泌细胞的轴突与胞体分离并膨大变形。线粒体结构发生改变，膜与内嵴消失。另外，轴浆运输中的神经分泌颗粒明显减少。

| Abstract: | The effects of cascade, one of the acylcarbamide-insect growth regulators, on the structures of cuticle and cerebral neurosecretory cells in oriental migratory locust (OML)Locusta migratoria manilensis (Meyen) were detected under optical-and electron-microscopes. The results showed that the epiderma of treated nymph was destroyed, the endocuticula turned obviously thinner and separated from epiderma. There were larger and unevenly distributed bullules in cytoplasm of epiderma, which nuclear chromatin aggregated, granulated and unevenly distributed. The number of cerebral neurosecretory cells, in which more larger vacuoles scttered and with aberrant and amplificate axon separated to cell body, in OML treated with cascade decreased significantly. The membrane and inner carinulae in deformed mitochondria were absent. In addition, the neurosecretory particles in transportation of axoplasm decreased markedly. |
