Resumo: Aedes aegypti is the primary vector of chikungunya, yellow and dengue fevers. Dengue fever is the major cause of child morbidity and hospitalisation in some Asian and African countries, while yellow fever is prevalent in Nigeria. The development of resistance to the available insecticides has necessitated the continued search for safer ones from plants. Eighteen plant extracts with ethnomedical claims of or demonstrated febrifuge, antimalarial, insecticidal and insect repellent biological activities were tested for activity against the fourth instar larvae of Aedes aegypti. About 61% of the eighteen extracts demonstrated high to moderate larvicidal activity. Extracts of Piper nigrum and Abrus precatorius seeds were the most active and the larvicidal constituent(s) of the latter should be determined.
