Influence of temperature on the fecundity and acetylcholinesterase activity of the fresh water snail Lymnaea acuminata

Arun Kumar Srivastava, Vinay Kumar Singh


The freshwater snail Lymnaea acuminata is the intermediate host of Fasciola gigantica which cause animal and human fasciolosis, respectively in different part of India. Vector snail Lymnaea acuminata is fast breeder and it lays eggs round the year. Temperature is an important abiotic factor which controls the metabolism of snail. High temperature increases fecundity of the snails. A population of glial cells in the central nervous system of the gastropod mollusk L. acuminata produces a soluble protein that  specifically binds acetylcholine and alters the reproductive capacity of the snail keeping in different temperature in different months of the year Nov-2011- Oct- 2012.
