The acute toxicity of endosulfan to three freshwater snails, Melanoides tuberculata (Muller, 1774), Thiara granifera (Lamarck, 1822) and Planorbella duryi (Weatherby, 1879), was determined in Jamaica. These three species are exotic to the island. The 24 hr LC50 values were 7.74, 5.35 and 4.26 mgL-1, respectively. The 96 hr LC50 values were 2.30, 1.74 and 1.35 mgL-1, respectively. The three species displayed avoidance reactions, which may have contributed to their higher tolerance of endosulfan in comparison to other aquatic invertebrates and fishes.
