Biological control of the intermediate hosts of S. mansoni and S. haematobium by means of a competitor snail,Helisoma duryi, has been suggested. In the present laboratory study, information was obtained concerning the interspecific competition between H. duryi and B. glabrata. The results indicated that the growth rate, mortality rate, and cercarial production of S. mansoni-infected B. glabrata were highly influenced by H. duryi. These observations agree with results obtained in earlier experiments concerning the interspecific competition between H. duryi and S. mansoni-infected B. pfeifferi. The exact characteristics of the influencing factor have not yet been determined, but the observations indicated that H. duryi could possibly be used as a biological control agent.
有人提出，借助竞争蜗牛杜氏泡螺对曼氏血吸虫和埃及血吸虫的中间宿主进行生物防治。在目前的实验室研究中，获得了有关杜氏泡螺和光滑双脐螺种间竞争的信息。结果表明，感染曼氏血吸虫的光滑双脐螺的生长率、死亡率和尾蚴产量受到杜氏泡螺的高度影响。这些观察结果与早期关于杜氏泡螺和感染曼氏血吸虫的费氏双脐螺种间竞争的实验结果一致。影响因素的确切特征尚未确定，但观察结果表明，杜氏泡螺有可能被用作生物防治剂。
