中华真地鳖的生殖系统

Reproductive system of Eupolyphaga sinensis

通过解剖分析中华真地鳖EupolyphagasinensisWalker雌雄内生殖系统和外生殖器的构造,比较不同生长期雌虫的内生殖系统变化,并依据雌虫外生殖器和最后一腹节的构造叙述了地鳖虫卵鞘的形成过程。结果表明:中华真地鳖雌性附腺和雄性附腺发达;雄性外生殖器的阳体结构较为复杂;雌虫外生殖器、腹末构造与卵鞘表面形态的形成有必然的关系。

The tissue of inner reproductive system and the structure of outer reproductive organ of Eupolyphaga sinesis Walker were studied. The ovarian development of the each growing season of E. sinensis was analyzed. The outer reproductive organ and relationship between conformation of the ninth abdomere and egg pouch were discussed. The results showed that the female gland accessory and the male gland accessory were full-growth, the male genitalia is complicated and the relationship between the last abdomere like the tubbiness and form of egg pouch is distinct.
