Ivermectin is lethal to Bulinus (Physopsis) globosus, Biomphalaria pfeifferi, and Lymnaea natalensis at concentrations of 0.08 micrograms/ml and above. Studies show that these snails will not recover from a 24 h exposure to 2.00 micrograms/ml of Ivermectin in the laboratory at 28 +/- 2 degrees C. A time dependent toxicity to snails was recorded and an exposure of adult snails to sub lethal concentrations significantly reduced the number of eggs laid (r = -0.08, t = 2.64, P less than 0.05).
