ABSTRACT

The molluscicidal effect of colchicine was evaluated against various stages of the freshwater snail Lymnaea stagnalis, immature, young mature and adults. Calculated values of lethal concentrations (LC50and LC100 ) showed colchicine as toxic against eggs, immature and adults. Results revealed that colchicine could be used to control harmful snails, as it significantly controls reproduction of these snails. The colchicine reduces fecundity, prolongs hatchability period and reduces survival of the newly hatched snails in a snail population, when exposed to a concentration lower than LC50. So, this investigation was made to know more about the intoxication of alkaloids of colchicines on the mortality and survivality of hatched young snail of pest snail.

Key words : Colchicine, Developmental stages, Lethal concentration, Lymnaea stagnalis.
