ABSTRACT
Toxicological studies on three ethanol extract preparations of Solanum nigrum L. leaves were made on Biomphalaria alexandrina. Extract [A], made by soaking leaves powder over night in cold 70% ethanol, has the highest activity, [LC[50] 3.37mg/L within 24 hr]. This extract also showed larvicidal activity against larvae of two mosquito species, Aedes caspius and Culex pipiens, [LC[50] 51.29 and 125.89 mg/L within 24 hr, and 21.38 and 38.11mg/L within 48 hr, respectively]. Sunlight, pH, and turbidity did not affect the activity of this extract, but the molluscicidal activity seems to be correlated with the increase of temperature. The concentrated extract [1000mg/L] can be stored at room temperature for six months without any change in its activity, but diluted solutions of this extract lost their activity after four weeks
