Larvicidal activity of Phyllanthus emblica Linn. (Euphorbiaceae) leaf extracts against important human vector mosquitoes (Diptera: Culicidae)
Journal Title: Asian Pacific Journal of Tropical Disease - Year 2012, Vol 2, Issue 0
Abstract
Objective: To determine the larvicidal activity of Phyllanthus emblica leaf extracts against Aedes aegypti and Culex quinquefasciatus. Methods: The larvicidal activity was determined against two vector mosquito species at concentrations of 50, 100, 150, 200 and 250 ppm. Larval mortality was assessed after 72 hours. Results: The leaf extracts of P. emblica was found to be more susceptible against the larvae of Cx. quinquefasciatus with a LC50 value of 78.89 ppm. Conclusions: These results suggested that the leaf extracts of P .emblica showed potential to be used as an ideal ecofriendly approach for the control of the Aedes aegypti and Culex quinquefasciatus.
