Abstract

The larvicidal activity of the essential oils from leaves of five species of Lippia (L. alba, L. aff. gracilis, L. gracilis, L. microphylla and L. nodiflora) was studied on third instar larvae of Aedes aegypti. The larvae were exposed to serial concentrations from 500 to 12.5 μg/mL of the essential oils. The results indicate that the oil of L. gracilis has a higher larvicidal activity with a LC50 of 26.3 μg/mL The results suggest the use of these essential oils as natural larvicidal agents.
