中华稻蝗雄性附腺和储精囊的组织学研究

Histological of male accessory glands and seminal vesicle of Oxya Chinensis (Insecta: Orthoptera)

通过腺体标本制作技术、石蜡切片技术和光镜观察,研究了中华稻蝗成虫的雄性附腺和储精囊的结构和功能.结果表明,由中胚层发育而来的附腺由15对(8对乳白管,7对透明管)一端开口于射精管,另一端封闭的腺管组成其组织由里到外为上皮层、底膜、肌肉层和结缔组织膜,并按上皮细胞,分泌物将乳白腺管分为酸性腺管和颗粒腺管,透明腺管分为碱性腺管、粘液性腺管和混合性腺管.这些腺管于成虫前后期在大小、上皮细胞、分泌物发生一些变化.精子在储精囊中成团分布,储精囊具柱状上皮细胞和分泌细胞,底膜和肌肉层较发达,围脏膜中有气管,其盲端和中后段组织结构有差异.

The structure and function of the mesoderm accessory glands and seminal vesicle in Oxya Chinensis (Insecta: Orthoptera), are studied with gland specimen, paraffin sections and light microscopy method. The results are summarized as follows: The male accessory glands of Oxya Chinensis (Insecta: Orthoptera) includes fifteen pairs of tubules opening into the ejaculatory duct, eight of them are white and seven hyaline glands. The histological structure of male mesoderm accessory glands showed it consisted of four layers: simple epithelium, basal lamella, muscle layer and peritoneal membrane. White glands are classified into two main types on the basis of epithelial cells and secretion: acidity and particulate glands, and hyaline into three——basicity, mucus and mixture. The size, epithelial cells and secretion changed after eclosion. Seminal vesicle, scattered with united sperm, consisted of four layers: columnar cell and secretary cell, developed basal lamella and muscle layer, peritoneal membrane, the blind and the other part had some difference in histological structure.
