Resumo: The insecticidal activities of extracts and oils of seventeen medicinal plants of Brazil have been determined using an Aedes aegypti larvicidal bioassay. Oils from Anacardium occidentalis, Copaifera langsdorffii, Carapa guianensis, Cymbopogon winterianus and Ageratum conyzoides showed high activities with LC sub(50) values of 14.5, 41, 57, 98 and 148 mu g/l, respectively. The most active ethanolic extract tested was that from the stem of Annona glabra which presented an LC sub(50) value of 27 mu g/l. The potential application of cashew nut oil, an industrial by-product with low commercial value, in the control of the vector of dengue and yellow fever, may be proposed.
