摘要

研究了粉蚧和粉蚧的精子超微结构。这些结果证实了黄粉虫总科精子的一般组织。精子生成结束时的精子束在生殖囊的两个相反极显示出相同的特殊反平行分布，这在其他黄粉虫总科中观察到。精子有一个双层顶体，一个在基底区有两个凹陷的长圆柱形细胞核，两个椭圆形的相等线粒体衍生物和两个三角形的附属体。鞭毛轴丝具有常见的9+9+2微管模式，在尾端导致紊乱。根据分子数据，所有这些精子特征都与Pythidae（一个亲缘关系密切的家族）中发现的特征非常相似。

The sperm structure of the Scraptiidae (Coleoptera; Tenebrionoidea)

The sperm ultrastructure of two members of the Scraptiidae Anaspis pulicaria and A. lurida was studied. The results confirm the general organization of the sperm in the superfamily Tenebrionoidea. The sperm bundles at the end of the spermiogenesis show the same peculiar antiparallel distribution at the two opposite poles of the germ cyst, observed in other Tenebrionoidea. The sperm have a bi-layered acrosome, a long cylindrical nucleus with two infoldings at its basal region, two elliptical equal mitochondrial derivatives and two triangular accessory bodies. The flagellar axoneme has the common 9 + 9 + 2 microtubular pattern that at the tail end results disorganized. All these sperm characteristics are quite similar to those found in Pythidae, a closely related family, according to molecular data.

期刊介绍： Micron is an interdisciplinary forum for all work that involves new applications of microscopy or where advanced microscopy plays a central role. The journal will publish on the design, methods, application, practice or theory of microscopy and microanalysis, including reports on optical, electron-beam, X-ray microtomography, and scanning-probe systems. It also aims at the regular publication of review papers, short communications, as well as thematic issues on contemporary developments in microscopy and microanalysis. The journal embraces original research in which microscopy has contributed significantly to knowledge in biology, life science, nanoscience and nanotechnology, materials science and engineering.
