Cymbopogon nardus , Syzygium aromaticum , and Citrus sinensis have been well known to possess insecticidal activity. Here, we investigated the repellent activity of individual of three essential oils ( C . nardus , S . aromaticum , C . sinensis ) and a combination of essential oils ( C . nardus + C . sinensis , C . nardus + S . aromaticum , and C. sinensis + S . aromaticum ) against a dengue vector, Aedes aegypti and a filarial vector, Culex quinquefasciatus . The essential oils (1 mg) were smeared evenly on the surface of the left arm (three volunteers) and then subjected to 25 females of A . aegypti and C . quinquefasciatus in the cage. The number of landed mosquitos was observed every hour for 7 hours to determine the protection index (PI). The result showed that individuals of three essential oils and a combination of essential oils generated > 90% of PI until 7 hours of application for both mosquitos species tested. Overall, the data demonstrated that individual of three essential oils, i.e., C . nardus , S . aromaticum , C . sinensis , and various combinations of essential oils ( C . nardus + C . sinensis ; C . nardus + S . aromaticum ; C. sinensis + S . aromaticum ) are promising as repellent agents against A . aegypti and C. quinquefasciatus .
