In the present paper , some investigations on loxoblemmus doenitzi ( gryllidae ) are reported . in order to discover the meiosis of spermatomeres and spermiogenesis , slice - pressing method and improved phenol - fuchsin dyeing method are used . in the course of meiosis , primary spermatocytes directly enter metaphase ii , not through telophase i and prophase ii 本论文以直翅目、螽斯亚目、蟋蟀总科、蟋蟀科的多伊棺头蟋( loxoblemmusdoenitzi )为材料，采用压片法-改良苯酚品红染色，研究了精子发生过程中的减数分裂阶段和精子形成，发现初级精母细胞第一次减数分裂后不经过末期和前期直接进入中期。
