The present study was undertaken to assess the ovicidal, larvicidal, and the repellent activity of Pterolobium hexapetalum an indigenous medicinal plant extracts of pentane, ethyl acetate and methanol against the selected vector Mosquitoes namely Aedes aegypti, Anopheles stephensi and, Culex quinquefasciatus. The undertaken results of Ovicidal activity of methanol extract of P. hexapetalumwas tested against the eggs of Aedes aegypti, 32.8%; Anopheles stephensi, 38.4%; Culex quinquefasciatus79.2% showed mortality of the eggs was increased with increased concentration of the extract respectively.. Methanol extract of P. hexapetalum also showed 96.82% insecticidal activity against the larvae of Aedes aegypti, 100% larvicidal activity against the larvae of Anopheles stephensi, and Culex quinquefasciatus at 25mg/l concentration of the extract. The repellent activity of methyl acetate extract against Aedes aegypti showed that 60.0±0.12%, 65.0±4.84% and 87.5±4.51% repellency was noted against the mosquitoes of An. stephensi and C. quinquefasciatus respectively.
