摘    要:利用组织学方法,观察了黄胫小车蝗Oedaleus infernalis 受精囊的显微与亚显微结构。结果表明,黄胫小车蝗受精囊为单个,由高度卷曲的受精囊管和蚕豆状的端囊构成。受精囊壁主要由表皮层、上皮层、基膜和肌肉层构成;上皮层包含上皮细胞、导管细胞和腺细胞。上皮细胞在靠表皮层的边缘有大量的微绒毛,两相邻上皮细胞的细胞膜相互嵌入,并有细微的突起延伸在导管细胞及腺细胞之间,直到基膜,达基膜处的上皮细胞膜折叠,与腺细胞膜的折叠,一起形成迷宫样的指状突起,附着在基膜上。导管细胞有一个较大的核和分泌导管,连接于腺细胞的细胞腔和受精囊腔,将腺细胞中分泌物运输到受精囊腔中。腺细胞具有典型的分泌细胞特征: 含发达内质网、高尔基复合体及不同大小的囊泡。肌肉层位于受精囊最外层,附在基膜上。在受精囊不同部位的结构有差异。在交配前和交配后,受精囊腺细胞的亚显微结构也有差异。

关 键 词:黄胫小车蝗  受精囊  显微结构  亚显微结构

Abstract:Microstructure and ultrastructure of the spermatheca of grasshopper Oedaleus infernalis Saussure (Orthoptera: Acridoidae) were investigated with light microscopy and transmission electron microscopy. The unpaired spermatheca can be subdivided into a multiple coiled tube and a bean-shaped terminal sac. The spermathecal wall from inside to outside consists of cuticula intima, epithelium layer, basal lamina and muscle layer. The epithelium layer is comprised of a layer of epithelial cells with a distinct apical microvilli border, a layer of ductule cells and gland cells, with the epithelial cells heavily intercalated with one another and slender projections extending between the ductule cell and the gland cell to basal lamina and folded. The basal plasma membrane of gland cell and epithelial cells form a huge labyrinth through extensive folding. The ductule cell transports secretion of gland cell. The gland cells show structures typical for secretion cell: ER, Golgi body and different size vesicles. Every gland cell contains a cellular cavity, which is coated with a microvilli border and connected with secretion ductules. By secretion ductules, the cellular cavity was connected with spermathecal lumen. In the outer layer is muscle layer attached to basal lamina. There are differences of structure in terminal sac and tube regions. Significant differences in ultrastructure of spermathecal gland cell before and after copulation were observed.
Keywords:Oedaleus infernalis  spermatheca  microstructure  ultrastructure
