Chemoattraction studies were done with Schistosoma mansoni adults from mice. To test for attraction or repulsion, some worm pairs were separated mechanically and the individuals placed in polycarbonate chambers. Experiments were done at 37 C and chambers contained dialysis tube chimneys. In all cases, heterosexual attraction occurred when one worm, but not two worms, were placed in the chimneys. Unperforated chimneys with specific molecular weight (Mr) exclusions were compared with perforated chimneys to study heterosexual attraction. Attraction was similar in designs using perforated chimneys and those with 50,000 and 12,000 Mr exclusions, but none was seen in chimney designs with 1000 Mr exclusions.
对来自小鼠的曼氏血吸虫成虫进行了化学吸引研究。为了测试吸引或排斥情况，一些虫对被机械分离，个体被放置在聚碳酸酯小室中。实验在37℃下进行，小室装有透析管烟囱。在所有情况下，当一个而非两个虫体被放置在烟囱中时，会发生异性吸引。将具有特定分子量（Mr）排除范围的无孔烟囱与有孔烟囱进行比较，以研究异性吸引。在使用有孔烟囱以及具有50,000和12,000 Mr排除范围的烟囱设计中，吸引力相似，但在具有1000 Mr排除范围的烟囱设计中未观察到吸引力。
