| 摘 要： | 本文利用扫描电镜和透射电镜分别对不同发育阶段的茶银尺蠖Scopula subpunctaria Herrich-Schaeffer雌蛾性信息素腺体进行了观察和研究,对探索信息素的合成途径提供科学依据。结果表明,雌蛾性信息素腺体位于第8、9/10腹节的节间膜上,由其表皮下方的单层上皮细胞组成,并几乎覆盖整个节间膜形成一个近乎完整的环状。成熟雌蛾(3日龄)性腺的超微结构照片显示性腺细胞具有发达的微绒毛、质膜内褶、大量的脂滴、细胞间的运输孔道以及细胞桥粒等结构组织。而在未成熟雌蛾(羽化5h内)性腺细胞内,这些结构均明显缺失或发育不完整。

| Abstract: | Different developmental stages of the sex pheromone gland of female Scopula subpunctaria Herrich-Schaeffer were observed using SEM(scanning electron microscope) and TEM(transmission electron microscopy) .The results show that the pheromone gland is formed by hypertrophied epidermal cells which occupy an almost complete ring at the intersegmental membrane between abdominal segments 8 and 9/10.Ultrastructure of the pheromone gland cells of mature(3 day old) female moths revealed distinct features,such as well... |
