DOIAbstract
The bioassay of the molluscicidal Activities of J. curcas leaves against Biomphalaria pfeifferi was investigated in vitro, using Crude and 70% methanolic extracts in a two- phased rapid and final screening test. The rapid screening of the crude extracts, for the minimal molluscicidal concentration (LC100), of the snails was less active (>500ppm), compared to the methanolic extracts (<500ppm). The final screening, revealed an LC50 and LC100 values of 6 and 30ppm respectively. Further investigation based on exposure, revealed a mortality within 12 hours, which meets WHO standard of less than 24 hours for a potential molluscicide. These results confirmed that J. curcas leaves can be regarded as a potential molluscicide for the control of schis...
