Larvicidal activity of Monstera adansonii plant extracts against Culex quinequefaciatus

Abstract

Mosquitoes transmit serious human diseases, causing millions of deaths every year and the development of resistance to chemical insecticides resulting in rebounding vectorial capacity. Controlling mosquitoes at the larval stage is easy as target specificity of the larvicide used can be ensured. Plants may be alternative source of mosquito control agents. The Present study assessed the role of larvicidal activities of methonal, chloroform, petroleum ether, (25, 50, 75, 100 mg) extracts of Monstera adansonii against early 4th instar larva of Culex quinequefaciatus. The larval mortality was observed after 12 h of exposure, The larvicidal effect of methanol and chloroform extracts was moderately less. However, the highest larval mortality rate was found in petroleum ether extract, This study indicates that Monstera adansonii plant possesses larvicidal activity against Culex quinequefaciatus and may be a possible source of mosquito larvicides.
