| Abstract | ||
| The molluscicidal effects of five ethanolic crude extracts, Cumin (Cuminum cyminum), Golden shower (Cassia fistula), Umbrella tree (Melia azedarach), Olive (Olea europaea) and pomegranate (Punica granatum) were evaluated against two land snail species, Monacha obstructa and Eobania vermiculata, under laboratory conditions. Three methods of bioassay were used, i.e. contact, leaf-dipping and bait techniques. The results indicated that the ethanol crude extract of Cumin was the most toxic extract for the two tested land snail species followed by Golden shower, Umbrella tree and pomegranate extracts while Olive extract had the lowest effect. The land snail, E. vermiculata was comparatively less susceptible to the tested plant extracts than the land snail, M. obstructa. Results showed that, contact technique of the tested plant extracts was the most effective method of application. The LC50 values of Cumin, Golden shower, Umbrella tree, Olive and Pomegranate extracts when applied as contact were 250, 325, 635, 1500 and 910 ppm for M. obstructa and 288, 380, 682, 1720 and 965 ppm for E. vermiculata, respectively. | ||
