Antimosquito Metabolites from Selected Medicinal Plants and Evaluation of Their Biochemical Toxicity in Culex Sp

Abstract

Transmittance of Mosquitoes affects human health every year and resists chemical insecticides with help of vectors. The larvicidal potential of different medicinal plant leaf extracts of three plants (Vitex trifolia, Vernonia cinerea and Premna integrifolia) was tested against the fourth-instar larvae of Culex sp. Chosen plant extracts screened larvicidal effect and found maximum larval mortality was detected in Venonia cinerea (LC50 89.13 and 141.54 ppm) followed by Premna integrifolia of methonal extract (LC50 83.5 and 139.5 ppm) and Vitex trifolia (LC50 113.0 and 156.0 ppm). In this findings supported to isolate the active compounds to control mosquito without any negative impact.
