Gerris的细胞质组分在精子发生过程中的历史，一般来说，类似于在Pentatomidae中描述的。对新鲜戏弄制剂的广泛研究证实了对固定物质的观察结果。在精母细胞生长期，线粒体的质量显著增加。在成熟分裂过程中，线粒体相对于中心粒的方向是非常恒定的。nebenkem是由分化为亲色和疏色部分的线粒体融合而产生的。早期精母细胞的高尔基体为水泡体，其外周为嗜锇性。这些在新鲜的细胞中是不可见的，但在未固定的细胞中，第一次分裂后期由它们融合而产生的团块是可见的。在新鲜的制剂中，这些团块内的非亲锇物质染成中性红色。只有高尔基团的亲锇部分参与分裂形成双胞体。有非常有启发意义的证据表明顶体的合成过程主要发生在囊状顶胞细胞（高尔基体）内。在精细胞中，在新鲜的制备物中，像顶胞细胞一样的物质是看不到的，除非在顶胞细胞内部或附着在顶胞细胞上，在那里它以“前顶体”物质的小球体的形式出现，它们融合形成顶体。
The history of the cytoplasmic components in the spermatogenesis of Gerris is, in general, like that which has been described in the Pentatomidae. The observations of fixed material have been checked by extensive studies of freshly teased preparations. During the spermatocyte growth period the chondriosomes undergo considerable increase in mass. During the maturation divisions the chondriosomes are remarkably constant in orientation with respect to the centrioles. The nebenkem arises by fusion of chondriosomes differentiated into chromophilic and chromophobic portions. The Golgi bodies of the earlier spermatocytes are vesicular bodies, the peripheries of which are osmiophilic. These are not visible in fresh preparations, but the masses resulting from their fusion in the late prophase of the first division are visible in the unfixed cells. The non-osmiophilic material inside these masses stains with neutral red in fresh preparations. Only the osmiophilic part of the Golgi masses is involved in the fragmentation to form dictyo-somes. There is very suggestive evidence that the process of acrosome synthesis largely takes place inside the sac-like acroblast (Golgi apparatus). In the spermatid, material which stains, in fresh preparations, like the acroblast is never seen, except inside or attached to the acroblast, where it appears in the form of small spheres of "pro-acrosomic" material, which fuse to form the acrosome.
