Abstract

The aim of this study was to evaluate the toxicity of four essential oils extracted from the following species of plants: Cymbopogon citratus, Cymbopogon nardus, Eucalyptus globulus and Eugenia caryophyllata on adult females of the mosquitoes Aedes aegypti and Anopheles albimanus. The tests were performed with adult mosquitoes of the reference colonies of the Entomology Laboratory of the Instituto Nacional de Salud de Bogotá. Of each essential oils the following concentrations were prepared: 0.5, 1.0, 1.5, 2.0 and 2.5 % v/v. The BioStat program was used to perform the Probit analysis and estimation of the LC and LC . The LC of C. citratus and C. nardus oils was 1.07 % for Ae. aegypti; and for An. albimanus 0.7 % and 1.86 % respectively. The LC of C. citratus and C. nardus oils respectively was 2.01 % and 1.96 % for Ae. aegypti and 1.3 % and 1.86 % for An. albimanus. The essential oil of Eucalyptus globulus showed to be more effective against An. albimanus adults. The Eugenia caryophillata oil had no effectiveness in mortality in the two species of mosquitoes. In conclusion, the essential oils of C. citratus and C. nardus showed to be the most effective against adults of Ae. aegypti and An. albimanus ©2013, Sociedad Venezolana de Entomología. 50 90 50 90
