Larvicidal activity of the grapefruit Citrus paradise (Rutaceae) on two vectors of dengue [Actividad larvicida de la toronja, Citrus paradisi (Rutaceae) sobre dos vectores del dengue]

Larvicidal activity of the grapefruit (Citrus paradisi) was tested against mosquitoes Aedes aegypti and Aedes albopictus, which represent potentials vectors of dengue fever. The CL50 of the essential oil of the grapefruit were 47,3 ppm and 85,1 ppm for Ae. aegypti and Ae. albopictus, respectively. The analysis of the oil by GC-MS, showed different components knowns as insecticides, which could explain the toxicity of this oil against mosquitoes. This toxic activity against Ae. aegytpi was higher in comparison whit another citrus oils, that suggest further researches in this line for be recommend in the different campaigns against the mosquito Ae. aegypti. In the literature revised we did not find research in where has been evaluated the essential oil of citrus against larvae of mosquito Ae. alboictus. © Facultad de Ciencias Biológicas UNMSM.
