通过电镜和光镜观察,追踪了小地老虎的真核和无核精子(束)在雄蛾和雌蛾的生殖道中发生的一系列后期变化.结果表明:真核精子在雄蛾贮精囊和复射精管中仍以精子束形式存在,但片层外长物全部消失;在雌蛾的受精囊中,其本体结构则从外套中脱壳“孵化”出来。无核精子在贮精囊中形成外套,在受精副囊中的无核精子绝大多数被分解.作者推论:大量的无核精子伴随着真核精子,对于真核精子的移动、营养、存活乃至最终的受精作用,都起着至关重要的作用。
A series of later changes of reproductive tract of male and female moths were observed by electron microscopy and light microscopy.The results showed that eukaryotic spermatozoa were highly expressed in seminal vesicle and complex The ejaculatory duct is still in the form of a sperm bundle, but all the laminae have disappeared. In the female’s spermathecae, its body structure is “hatched” from the outer shell. Non-nuclear sperm form a coat in the seminal vesicle, the vast majority of non-nuclear sperm in the fertilization vice capsule is decomposed .According to the author: a large number of nuclear-free sperm accompanied by eukaryotic sperm, the movement of eukaryotic sperm, nutrition, survival and even The final fertilization, all play a vital role.
