Several field experiments were carried out in Senegal to evaluate the molluscicidal activity of Ambrosia maritima L. Applications of 400 mg L-1 of dry leaves of the plant in creeks of the Lampsar river did result in a reduction of Bulinus spp of 54-56% 2 weeks after treatment. Treatment of a closed irrigation canal caused a reduction of the density of Biomphalaria pfeifferi up to 77% 2 weeks after the application of 150 mg L-1 and 300 mg L-1. In both trials, however, a quick increase in the snail density was observed after treatment. It is concluded that the large amounts of crude plant material required to achieve snail reductions of less than 80% compromise the use of A. maritima in schistosomiasis control programmes.
在塞内加尔进行了多项田间试验，以评估滨海豚草的杀螺活性。在Lampsar河的小溪中施用400毫克/升的该植物干叶，处理两周后，双脐螺属减少了54 - 56%。在封闭灌溉渠中施用150毫克/升和300毫克/升后，2周内费氏双脐螺密度降低了77%。然而，在这两项试验中，处理后均观察到蜗牛密度迅速增加。得出的结论是，要使蜗牛数量减少不到80%，需要大量的粗植物材料，这不利于滨海豚草在血吸虫病控制计划中的应用。
