Abstract Dengue, a mosquito-borne febrile viral disease, is found in tropical and subtropical regions and is now extending its range to temperate regions. Malaria is a life-threatening mosquito-borne blood disease caused by a Plasmodium parasite and it is transmitted to humans through the bite of Anopheles mosquito. Plants possess rich source of secondary metabolites, inclusive of mosquitocidal properties apart from to their biodegradable capacity they are considered good candidates for controlling mosquitoes. Study aimed to investigate the larvicidal, Ovicidal and adulticidal activity of hexane, benzene, chloroform, ethylacetate and methanol dried leaf of Poncirus trifoliata against Anopheles stephensi and Aedes aegypti mosquito vectorts. larvicidal, ovicidal and adulticidal activities of plants extract were studied in the range of 100–500 mg/l in the laboratory bioassays against Anopheles stephensi and Aedes aegypti. The LC50 and LC90 values were calculated after 24 h by probit analysis. The results revealed compared to the four solvent methanolic P. trifoliata leaf extract was more effective ovicidal activity against the two vector mosquitoes tested. The leaf extract of P. trifoliata tested against the larvae of An. stephensi and Ae. aegypti, the larvae of An. stephensi were more susceptible than and Ae. aegypti.
