Larvicidal activity of Phyllanthus emblica Linn. (Euphorbiaceae) leaf extracts against important human vector mosquitoes (Diptera: Culicidae)

ObjectiveTo determine the larvicidal activity of Phyllanthus emblica leaf extracts against Aedes aegypti and Culex quinquefasciatus.MethodsThe 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.ResultsThe 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.ConclusionsThese 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.
