近年来,血吸虫的淡水螺蛳宿主的生物防制已引起更多的重视,但对这种生物防制剂的效果很少在实验室以外的条件下进行实验。本文是总结生物防制螺类中间宿主的现状,不只是指出我们对这课题,特别是那些有实用价值的种类的认识的不足之处,而且确定值得进一步优先予以支持的研究和活动。 In recent years, biological control of Schistosoma japonicum freshwater snail has attracted more attention, but the effect of this biological control agent rarely experimental conditions outside the laboratory.
