Toxicities of insecticides to three kinds of fresh water snails were evaluated. The test organisms are Physa acuta, Semisulcospira libertina and Cipangopaludina chinensis. The fresh water snails are quite low susceptible to insecticides and LC50 values of organophosphates, pyrethroids, and neonicotinoids ranged from 0.84 to >100 ppm.
