Cite article:- Alam H.M., Kaur* Arvinder, Jyoti, Singh N.K., Haque M., Rath S.S. (2024). MOLLUSCICIDAL EFFECTS OF METHANOLIC EXTRACT OF AZADIRACHTA INDICA (NEEM) ON SNAILS LYMNAEA AURICULARIA AND INDOPLANORBIS EXUSTUS*. Indian Journal of Animal Research. 44(3): 178 - 182. doi: .
The molluscicidal effect of methanolic extract of different components of neem plant (leaf,
seed, bark and whole plant) was evaluated against snails Lymnaea auricularia and Indoplanorbis
exustus. The extracts were prepared by cold extraction method by standard protocols. The
concentrations of extracts used were 1:10, 1:15, 1:20, 1:25, 1:30 and 1:35 and the results were
recorded at different period of exposure time (6 h, 12 h, 24 h, 48 h, 72 h and 96 h). The different
concentrations of methanolic extract of neem showed variable effect on adult stages of L. auricularia
and I. exustus. A total of 15 snails were used in triplicate in each treated and control group, respectively.
It showed positive correlation between exposure time and mortality and negative correlation between
dilution and mortality. Among the different extracts, the whole plant extract was most effective
followed by seed, leaf and bark against snails L. auricularia and I. exustus. I. exustus was found to be
more susceptible to methanolic extract of neem as compared to L. auricularia.
