Abstract

Aedes aegypti check for this species in other resources L. is the major vector of dengue fever, an endemic disease in Brazil. In an effort to find effective and affordable ways to control this mosquito, the larvicidal activities of essential oils from nine plants widely found in the Northeast of Brazil were analyzed by measurement of their LC50. The essential oils were extracted by steam distillation and their chemical composition determined by GL-chromatography coupled to mass spectroscopy. The essential oils from Cymbopogon citratus check for this species in other resources and Lippia sidoides check for this species in other resources , reported in the literature to have larvicidal properties against A. aegypti, were used for activity comparison. The results show that Ocimum americanum check for this species in other resources and Ocimum gratissimum check for this species in other resources have LC50 of 67 ppm and 60 ppm respectively, compared to 63 ppm for L. sidoides and 69 ppm for C. citratus. These results suggest a potential utilization of the essential oil of these two Ocimum species for the control of A. aegypti.
