Resumen
Siendo que es el Aedes aegypti considerado el vector causante
de la transmisión del dengue, la fiebre y la chikungunya. Es un
pequeño insecto como su morfología lo indica es de coloración
obscura con rayas blancas en el dorso y patas. Cada hembra
puede depositar una cantidad aproximada de 80 a 150 huevos.
El mosquito adulto vive en un radio de cien metros de su
criadero. Según la OMS, se estima que esta especie de mosquito
causa 50 millones de infecciones y 25.000 muertes por año .
Esta investigación tiene como objetivo marcar un mapa
conceptual porque es necesario descubrir la susceptibilidad del
vector Aedes Aegypti al larvicida “Temephos”. Como quedo
demostrado en el estudio que se realizado en la parroquia
Febres Cordero y Ximena del Cantón Guayaquil.
Materiales y Métodos: Para que se realice el análisis de
susceptibilidad donde se capturaron alrededor de 400 larvas de
Aedes. Aegypti de 12 criaderos de las dos parroquias a evaluar;
cada uno de los depósitos fueron registrados con sus
características físicas, a las cuales se les administró 0,05 gr de
Temephos en 500 ml de agua.
Resultados: De 360 larvas analizadas en la parroquia Febres
Cordero y Ximena: 204 larvas que corresponden al 56,6%
mueren a los 30 minutos de exposición. Mientras que a 60
minutos 357 mueren que corresponde al 99,1%. Pero el 09%
presentan resistencia a los 60 minutos en estas zonas de Estudio,
mientras que a las 24 horas 358 larvas mueren y dos resisten lo
que significa un reporte de resistencia muy baja.
Since Aedes aegypti is considered the cause of the transmission of dengue vector, fever and chikungunya. It is a tiny insect morphology suggests is of dark color with white stripes on the back and legs. Each female may deposit an amount of 80-150 eggs. The adult mosquito lives within a hundred yards of her kennel. According to the WHO, it is estimated that this species of mosquito causing 50 million infections and 25,000 deaths per year. This research aims to mark a conceptual map that is necessary to discover the susceptibility of Aedes aegypti vector to larvicide "Temephos". As was demonstrated in the study that was conducted in the parish Febres Cordero and Ximena of Guayaquil. Materials and Methods: For the sensitivity analysis where about 400 Aedes larvae were captured is made. 12 aegypti breeding sites of the two parishes assessed; each of the deposits were recorded with their physical characteristics, to which were administered Temephos 0.05 g in 500 ml water. Results: Of 360 larvae analyzed in the parish Febres Cordero and Ximena: 204 larvae that correspond to 56.6% die within 30 minutes of exposure. 60 minutes while die 357 corresponding to 99.1%. But 09% are resistant at 60 minutes in these areas of study, while 24 hours 358 larvae die and two resistant which means a report very low resistance
