作者于1974～1975年间在沃尔特湖边一村庄的5个主要感染埃及血吸虫的水接触点进行了生态学或生态学结合化学药物控制血吸虫病的试验。生态学控制方法为除去湖边水接触点的植物,结果试验前的两个螺类密度类似区域,经清除植物后不论螺类密度及带尾蚴螺数均显著下降,但不能完全阻断血吸虫病的传播。生态学结合化学药物的方法为清除植物 The authors conducted a pilot study of chemical or ecological control of schistosomiasis at the water-contacting points of five major schistosomiasis spp. Infected in the village of Walter Lake in 1974-1975. The ecological control method is to remove the plants at the lake water contact point. As a result, the two snail-like density-like areas before the test were significantly decreased after the plants were cleared, regardless of the density of the snail and the number of cercariae, but they could not completely block the schistosomiasis Spread. The method of ecologically combining chemicals is to remove the plant
