Background  Intestinal schistosomiasis caused by  Schistosoma mansoni  is a wide spread disease in most parts of Ethiopian highlands. Snail control is one major strategy in schistosomiasis control. The use of molluscicidal plant products is becoming interesting due to their environmental friendliness, accessibility and easy application. This research is aimed to evaluate the molluscicidal effect of  Achyranthes aspera  on  Biomphalaria pfeifferi  and  Lymnaea natalensis  snails, which are of great medical and veterinary importance in Ethiopia.    Methods  Adult  B. pfeifferi  snails were exposed to the various concentrations of  A. aspera  aqueous leaf extract for 24, 48 and 72 h. Similarly, adult  L. natalensis  snails were exposed to the extract for 24 h. Mortality data were analyzed using probit regression model. Phytochemical content of the plant was analyzed using standard screening methods.    Results  The plant’s molluscicidal effect on the two snail species was demonstrated. The 24 h LC 50  and LC 90  values against  L. natalensis  were 69.5 and 93.9 ppm respectively. In the 24, 48 and 72 h exposure of  B. pfeifferi , the LC 50  values were 72.4, 69.9, 64.7 ppm and the LC 90  were 96.5, 93.8, 92.8 ppm, respectively. The phytochemical screening tests indicated presence of saponins.    Conclusion  From the findings of this study,  A. aspera  has a molluscicidal potential. The result provides a useful foundation for further in-depth studies to ensure its wider applicability in different water bodies and evaluate its toxic effects on non-target species.
