Abstract: The aqueous and acetone extracts of Lantana indica Roxb. leaves were governed for 24 to 96 hours to the freshwater snails, Lymnaea acuminata and larvae of Culex quinquefasciatus mosquitoes in order to test their lethality. It was observed that the acetone extract of leaves has potent toxic effect against both the vectors in time and dose dependent manner. There was a significant negative correlation between LC values of the extracts and the exposure period, thus LC50 values decreases from 7.32 mg/l (24 hours) to 1.02 mg/l (96 hours) against L. acuminata and 10.99 mg/l (24 hours) to 5.18 mg/l (96 hours) against C. quinquefasciatus larvae. It is clear from this study that the active moiety extracted from this plant may prove to be of great promise for being used as natural pesticide for vectors control.
