Evaluación de la posible actividad larvicida de aceites esenciales frente a el aedes aegypti vector transmisor del dengue

Abstract

This project evaluated the larvicidal activity of 14 essential oils that belong to the Verbenaceae, Poaceae, Rutaceae, Lamiaceae, Myrtaceae and Annonaceae families, plus 3 commercial pesticides against Aedes aegypti pursuing the methodology proposed by the World Health Organization. The study was performed in third instar larvae and mortality was observed 48 hours later. From the essential oils, Lippia graveolens proved to be the most effective with CL50=19.93± 0.45 ppm and CL100= 34.81± 0.99 ppm, while Cymbopogon martinii was the less effective with CL50= 81.56± 1.21 ppm and CL100= 140.55± 2.07 ppm. On the other hand the most effective pesticide was the Temefos with CL50= 0.023± 0.001 ppm and CL100= 0.094± 0.002 ppm.
