Evaluación del efecto larvicida del extracto etanólico de Citrus latifolia (limón o lima ácida tahití) sobre larvas de cuarto estadio de Aedes aegypti en condiciones de laboratorio

Abstract

The larvicidal effect of the ethanolic extract of Citrus latifolia (lemon or Tahiti acid lime) was evaluated for the biological control of larvae in stage IV of Aedes aegypti in laboratory conditions, where it was obtained that the ethanolic extract of Citrus latifolia is an alternative favorable because it achieves a lethality of 97% in a sample of 100 individuals at a concentration of 700 ppm after 24 hours of exposure, and at a concentration of 500 ppm it has a lethality of 56% in individuals exposed to the substance, reaches the time 50% lethal at 36.7 hours and 90% at 74.4 hours after the Citrus latifolia extract came into contact with the Aedes aegypti sample. When carrying out the analysis with Probit units, it was obtained that the exact concentration to reach the LC50 of the sample in Aedes aegypti is 513 ppm of the ethanolic substance, and to achieve the LC90, individuals must be subjected to a concentration of 688 ppm, to achieve the effectiveness of the Citrus latifolia ethanolic extract as a larvicide.
