Laboratory evaluation of the molluscicidal properties of some Saudi Arabian euphorbiales against Biomphalaria pfeifferi

Laboratory studies were conducted to evaluate the molluscicidal properties of three Saudi Arabian Euphorbiales. The results showed that the methanol extract of Euphorbia schimperiana has a high molluscicidal potency. The activity remains stable over a wide range of temperature and pH values, in the presence of organic and inorganic substrates and after exposure of the solutions to ultraviolet radiation.
