Abstract The current study included testing the toxicity of Mesurol pesticide and its effects on the freshwater snail Viviparous bengalensis. Snails’ mortality is recorded at each 24 hours with a replacement of solution toxicity in order to avoid volatilization. Value of LC50 is obtained and is (0.55) mg/l, during the period of 96 hours. No mortality is noticed in the control treatment for the duration of the experiment, and the toxicity of Mesurol pesticide is very toxic and deadly impact on the snails.
