摘  要:基于李氏长尾线虫(Seinura liiHuang & Ye,2006)与吴氏长尾线虫(S.wuaeHuang & Ye,2006)是一对形态很相似的姊妹线虫,在原始描述之后,采用单一配对杂交方法来进一步探讨它们相互间的生殖关系。结果表明,李氏长尾线虫与吴氏长尾线虫在生殖上相互隔离,并且它们之间的生物学特性可能存在着较大差异;研究还表明,李氏长尾线虫与吴氏长尾线虫的生殖方式都为有性生殖。Due to Seinura lii was very similar to S. wuae in morphology. The following hybridization test was taken after they were originally described to learn more about the reproductive relationship between them by the method of single-pair reciprocal interbreeding. And the results showed that S. lii and S. wuae were reproductively isolated, additionally biological features of both species might vary considerably. Results also indicated that both Seinura species studied reproduced by amphimixis.
