Abstract
This study was conducted to investigate the ovicidal and molluscicidal potency of the aqueous extracts of the indigenous herb Pulicaria crispa leaves (El-Tagar) against four stages of Biomphalaria pfeifferi snails, the intermediate host of Schistosoma mansoni in the Sudan. Three parameters were used in this respect: water-extracting volume, soaking time for extraction and water source. The first and second parameters have shown significant differences on lethal doses, while the third one hasn’t.
