长翅素木蝗精子发生观察

Spermatogenesis in Shirakiacris Shirakii (I. Bol.)

首次对四平地区蝗属优势种——长翅素木蝗(Shirakiacris shirakii(I．Bol．))精子发生过程进行显微水平的观 察和描述．根据精母细胞形态和细胞核形态变化等特征性指标,蝗虫精子发生过程分为五个阶段,分别为精原细胞时 期、初级精母细胞时期、次级精母细胞时期、精子细胞时期和精子形成时期等,最终成熟的精子通过交配活动排出体外．

We first studied the spermatogenesis of Shirakiacris shirakii （I. Bol.） in histological levels. Five stages in spermatogenesis of Shirakiacris shirakii（I. Bol. ） had been distinguished and described respectively according the changes of the spermatocyte＇ s and nuclear, s shape. The five stages were spermatogonia,primary spermatocyte, second spermatocyte, sperm cell and spermiogenesis etc.
