The life-cycle of the nematode Rhabdochona phoxini, an intestinal parasite of the fish Phoxinus phoxinus, has been studied experimentally. The mayfly nymphs, Habrophlebia lauta Eaton and H. fusca (Curtis) were found to serve as experimental intermediate hosts. After the eggs of R. phoxini have been swallowed by the mayfly nymph, the toothed first-stage larvae of this parasite are released and penetrate through the intestinal wall into t-e body cavity of the mayfly. Before reaching the infective third stage, the larvae moult twice in the body of the invertebrate host (2 to 16 and20 to 36 days after infection at water temperatures of 13--15 degrees C). However, the development of the encysted infective larvae does not cease in the intermediate host and the larvae may undergo one more moult. One of two moults then occur in the intestine of the definitive host (Phoxinus phoxinus) (depending on the fact whether it was infected with third- or fourth-stage larvae) before the larvae attain the maturity. The development of R. phoxini in the definitive host lasts about two months.
对鱼类麦穗鱼肠道寄生虫——麦穗球线虫的生命周期进行了实验研究。发现蜉蝣若虫Habrophlebia lauta Eaton和H. fusca（柯蒂斯）可作为实验中间宿主。麦穗球线虫的卵被蜉蝣若虫吞食后，该寄生虫具齿的第一期幼虫被释放出来，并穿过肠壁进入蜉蝣的体腔。在达到感染性第三期之前，幼虫在无脊椎动物宿主体内蜕皮两次（水温13 - 15摄氏度时，感染后2至16天和20至36天）。然而，包囊化感染性幼虫的发育在中间宿主体内并未停止，幼虫可能再蜕皮一次。然后，在幼虫成熟之前，两次蜕皮中的一次发生在终末宿主（麦穗鱼）的肠道内（取决于其感染的是第三期还是第四期幼虫）。麦穗球线虫在终末宿主体内的发育持续约两个月。
