摘要: 棉铃虫Helicoverpa armigera Hubner雌蛾的性外激素分泌腺是一个完整的上皮环,位于第八、九腹节之间。羽化2天雌蛾的腺体细胞方形,比未分化的上皮细胞大。腺体折皱,表面密布小毛,小毛无孔。表皮可分二层:上表皮和内表皮。上表皮致密,较薄,厚度均匀。内表皮厚度有变化,较厚,由12-14层呈螺旋状排列的几丁微丝组成,有上皮丝穿人,构成孔道。顶部细胞膜组成微绒毛,底部细胞膜有内折。细胞质内有粗面内质网,光面内质网,高尔基氏复合体、脂肪滴、糖原及线粒体等细胞器。大的细胞核位于中下部。

Abstract: The sex pheromone-producing gland of cotton bollworm Helicoverpaarmigera Hiibner is a modified intersegmental membrane as a complete ring of glandular epithelium between the eighth and ninth abdominal segments. The gland cell of 2-day old female moth is cuboidal and larger than the epidermal cell in unmodified intersegmental membrane. It is highly convoluted with a dense scattering microspines without pores on the surface. The cuticle has two layers:epicuticle and endocuticle. The epicuticle is dense and relatively uniform in thickness. The endocuticle varies in thickness and consists of 12-14 lamellae of helicoidally arrangedmicrofibrils on which there are pore canals formed by epicuticular filament. The apical surface of plasma membrane has well-organized microvilli. The basal plasma membrane is also folded. The cytoplasm contains rough endoplasmic reticulum, Golgi complexes, lipid droplets, glycogen deposits, and mitochondria. The largeetlipsoidal nucleus is usually in subcentral position.
