摘要
滞育和非滞育棉铃虫在不同的发育阶段,脑的形态组织学结构存在着一定的差异,主要表现在:非滞育脑的神经纤维体发达,神经分泌细胞中的核较大,且细胞质中除了有线粒体外,还有大量的粗面内质网及游离的核糖体;而滞育脑的神经纤维体相对固缩、不发达,神经分泌细胞中核较小,细胞质中含有线粒体、光滑内质网和特有的脂滴,不具粗面内质网.这些证据表明滞育棉铃虫的脑活性相对较低.
In different developmental stages, there are some differences in the morphology of brain between diapause and non diapause destined H armigera .In the non diapause active brains, there is a much greater volume of neural fibril body, the neurosecretory cells have bigger nuclei and their cytoplasms contain an abundance of rough endoplasmic reticulum and free ribosomes.In diapause inactive brains, there is smaller volume of neural fibril body, the neurosecretory cells have small nuclei and their cytoplasms contain smooth endoplasmic reticulum and some lipid droplet, few rough endoplasmic reticulum
