Resumen
El objetivo de esta investigación fue demostrar mediante ensayos la actividad larvicida que posee la semilla de Annona muricata ecuatoriana frente a larvas en estadio I, II y III de la especie Aedes aegypti. El protocolo de ensayo consistió en la aplicación de concentraciones de 15, 25, 40, 70 y 100 ppm de los extractos etanólico y metanólico de la semilla de Annona muricata en envases que contenían larvas de Aedes aegypti. De acuerdo a los resultados se observó una mortalidad total de las larvas antes de las 14 horas en la mayoría de los casos. Los resultados demostraron la toxicidad del extracto etanólico y metanólico de Annona muricata y su eficiencia en la eliminación de las larvas de estadio I, II, III de Aedes aegypti, estos datos concuerdan con autores que han realizado ensayos con variedades similares de semillas y diferentes especies de vectores. Los extractos alcohólicos obtenidos de la semilla de Amuricata pueden resultar una herramienta muy útil en la disminución de la propagación de enfermedades virales provocados por mosquitos en el Ecuador.

The test protocol consisted of the application of concentrations of 15, 25, 40, 70 and 100 ppm of ethanolic and methanolic extracts of Annona muricata seed in containers containing larvae of Aedes aegypti. According to the results a total mortality of larvae was observed before the 14 hours in most cases. The results demonstrated the toxicity of ethanolic and methanolic extract of Annona muricata and its efficiency in the elimination of larvae stages I, II, III of Aedes aegypti, this data agrees with authors who have carried out assays with similiar varieties of seeds and different species of vectors. .The alcoholic extracts obtained from the A. muricata seed can be a very useful tool in reducing the spread of viral diseases caused by mosquitoes in Ecuador.
