Abstract
Essential oils obtained from Ocimum americanum, O. basilicum, O. basilicum fa. citratum, O. gratissimum and O. tenuiflorum, were tested for mosquito repellent and larvicidal activities. All the oils exhibited both activities. O. basilicum showed the strongest larvicidal activity (EC 50 = 81, EC 90 = 113 ppm), while O. gratissimum exhibited the longest duration of action for mosquito repellent activity (more than two hours). Gas chromatographic analysis indicated the presence of camphor, caryophyllene oxide, cineole, methyleugenol, limonene, myrcene, and thymol, all known insect repellents. © 1994, Gustav Fischer Verlag, Stuttgart · Jena · New York.
