Molluscicidal Activity of Synthetic and Plant Extracts on the Reproduction of snail Lymnaea acuminata

Shiv kumar, vinay kumar Singh

Abstract


Snail, Lymnaea acuminata, is the intermediate host of liver fluke Fasciola hepatica—causative agent of fascioliasis. The sublethal concentration (20% and 60% of 24 h LC50) of synthetic and plant extracts were studied on the reproduction of snail L. acuminata. Both the synthetic (Permethrin and Cypermethrin) and plant extract (Allium sativum and Annona squamosa) caused a significant reduction in the fecundity, hatchability and survival of young snail L. acuminata and also increased the hatching period (9–20 days) of snail with respect to the control (7–9 days). The synthetic molluscicides are more potent as compared to the plant molluscicides. It causes significant (p<0.05) reduction in the fecundity, hatchability and survival of young snail L. acuminata.
