The phytochemical constituents and the larvicidal and mosquito repellent activities of selected plants of Nyctaginaceae family viz., Boerhaavia diffusa, Bougainvillaea spectabilis, Mirabilis jalapa and Pisonia grandis were studied. Mirabilis jalapa demonstrated potential larvicidal and repellent activities against the mosquitoes than the other three plant species, which may be due to the presence of secondary metabolites in it. The results also indicated that the mosquito species Aedes aegypti was found to be more resistant as compared to Anopheles stephensi and Culex quinquefasciatus
