日本纺织娘的精子超微结构（直翅目：螽斯总科，纺织娘科）

对日本纺织娘Mecopoda nipponensis的精子超微结构进行了透射电镜观察。结果表明：其顶体复合体侧生于细胞核上且包裹了核顶端的部分；细胞核致密，横切面多为新月形或半月形；2蚕豆形副体位于9+9+2轴丝的两侧；线粒体衍生体横切面为椭圆形，其基质几乎完全晶状化；线粒体衍生体一侧的2扁平膜池横切面近S形；轴丝与线粒体衍生体之间有3条连接带，其中中央的一条呈环状；在有些尾部横切面中，质膜之内又有一双层膜把尾部的细胞器围绕起来。

Spermatozoon ultrastructure in Mecopoda nipponensis(Othoptera: Tettigonioidea, Mecopodidae)

This paper describes the spermatozoon ultrastructure in Mecopoda nipponensis (De Haan). Spermatozoon of this species were examined by transmission electron microscopy after double fixation of live material in glutaric-aldehyde and osmic acid. Its acrosomal complex lies to the side of the flat, dense nucleus and partially embraces it. Two broad bean-shaped accessory bodies are located laterally to the axoneme, which is of a typical 9+9+2 pattern. Two almost completely crystallized mitochondrial derivatives are oval in cross-section. There are three connecting bands between mitochondrial derivatives and axoneme. Two flat membranous cisterns close to mitochondrial derivatives are S-shaped in cross-section. A character peculiar to this species, an additional bi-layer membrane, appears around organelles of the tail in some cross-sections.
