Abstract

Molluscicidal effects ofAwdirachta indica (A. Juss), Melia composita (WiIld), Polygonum orientale (Linn.), Cucumis melo (Linn.), Argemone mexicana (Linn.), Eucalyptus spp. (Linn.), Vitex negundo (Linn.), Imperata cylindrica (L) P. Beauv. and Datura Jastuosa (Linn.) against Lymnaea (Pseudosuccinea) acuminata (Lamarck) f. rufescens (Gray), L(P) luteola f. ovalis (Gray), Indoplanorbis exustus (Deshyes) and Digoniostoma pulchella (Benson) was investigated using aqueous and methanolic extracts of the plants. Both aqueous and methanolic extracts of all the plants showed effective molluscicidal activity against all the snail species at 100, 50 and 25 mg litre−1 of water concentration from 12 to 72 h of observation. Irrespective of concentrations, methods of extraction and snail species, D. fastuosa showed highest molluscicidal effect followed by I. cylindrica. Aqueous extracts of the plants were found to possess better molluscicidal property than the methanolic extracts irrespective of snail and plant species as well as concentration of extracts used.
