Pellioditis pellio (Nematoda) adults showed heterosexual chemoattraction and female homosexual chemoattraction in an in vitro bioassay without barriers. Male-to-female heterosexual, but no homosexual chemoattraction, was observed whenM r 25,000 pore size dialysis tube chimneys (barriers) were used to restrain female attractor worms. Less attraction was seen whenM r 12,000 pore size barriers were used. The results suggest the presence of at least two types of chemoattractant for this species and that at least one heterosexual chemoattractant is betweenM r 12,000 and 25,000.
在没有障碍的体外生物测定中，Pellioditis pellio（线虫）成虫表现出异性化学趋向性和雌性同性化学趋向性。当使用 25,000 道尔顿分子量的透析管烟囱（障碍）限制雌性引诱虫时，观察到雄性到雌性的异性化学趋向性，但没有同性化学趋向性。当使用 12,000 道尔顿分子量的屏障时，观察到的吸引力较小。结果表明，该物种至少存在两种类型的化学引诱剂，至少有一种异性化学引诱剂的分子量在 12,000 至 25,000 之间。
