| dc.description.abstract | En el presente trabajo de investigación se determinó el efecto del lauril sulfato de sodio (SLS) sobre larvas de Aedes aegypti en condiciones de laboratorio; así como las diferentes concentraciones de SLS que ocasionan la muerte de larvas de A. aegypti y los mecanismos de acción que ocasiona el SLS. Para ello se utilizó lauril sulfato de sodio a concentraciones de 150 ppm, 300 ppm y 450 ppm y larvas III de A. aegypti; las mismas que se obtuvieron a partir de adultos provenientes de una población silvestre; criadas bajo un sistema de iluminación constante; a una temperatura de 26 °C ± 1 °C y un pH de 7,0. El ensayo piloto se realizó en vasos descartables, conteniendo 100 mL de agua potable con 20 larvas para cada una de las concentraciones consideradas; obteniendo el mayor efecto biocida a una concentración de 300 ppm de SLS. Posteriormente se las expuso en biorreactores tipo airlift modificado utilizando las mismas concentraciones del ensayo piloto; obteniéndose el mayor efecto biocida a 450 ppm de SLS. Las evaluaciones de mortalidad larvaria se realizó hasta las 24 horas después de la exposición, ocurriendo el mayor efecto larvicida con la concentración de 450 ppm. | |

For this, sodium lauryl sulfate was used at concentrations of 150 ppm, 300 ppm and 450 ppm and larvae III of A. aegypti; the same ones that were obtained from adults from a wild population; raised under a constant lighting system; at a temperature of 26 ° C ± 1 ° C and a pH of 7.0. The test plant level test was carried out in disposable cups, containing 100 mL of drinking water with 20 larvae for each of the concentrations considered; obtaining the greatest biocidal effect at a concentration of 300 ppm SLS. They were subsequently exposed in modified airlift bioreactors using the same concentrations as in the pilot test; obtaining the greatest biocidal effect at 450 ppm SLS. Larval mortality evaluations were performed up to 24 hours after exposure, with the greatest larvicidal effect occurring at a concentration of 450 ppm. | |
