          Abstract

          Resumen:Actualmente varias enfermedades de origen vectorial tienen una gran relevancia médico-veterinaria, debido a las adaptaciones que han desarrollado las especies involucradas en su transmisión. Se llevó a cabo una encuesta entomológica durante 2013 con el objetivo de actualizar los conocimientos ecológicos de las poblaciones de Aedes aegypti presentes en tres Áreas de Salud de Camagüey, Cuba. Se cuantificó en cada depósito o receptáculo positivo las larvas y pupas según ubicación en las viviendas, determinando el porcentaje de representatividad. Se calculó el Índice Pupal por Depósitos específicos (ÍPDe). Los totales de viviendas así como los depósito permanentes y útiles positivos fueron comparados entre estaciones climáticas, utilizando la prueba no paramétrica de Chi2 en tablas de contingencia de 2 X 2, mientras que la relación existente entre el total de viviendas positivas y los depósitos positivos permanentes y útiles, fue explorada a través del test de proporciones de hipótesis, con un nivel de significación de P ≤ 0.05. A. aegypti colonizó 73 tipos de depósitos siendo permanentes y útiles el 23.2 %. Este número incluyó el 76 % de los depósitos positivos. Hubo mayor colecta en el exterior en tanques bajos y toneles con importante producción pupal (ÍPDe = 3.04 y 1.75, respectivamente), así como diferencias significativas durante la estación lluviosa al comparar el número de viviendas positivas (PUIA: Chi2 = 32.89; P = 0.00; PUE: Chi2 = 127.44; P = 0.00 and PUJAM: Chi2 = 127.44; P = 0.00), y depósitos permanentes y útiles (PUIA: Chi2 = 30.37; P = 0.00; PUE: Chi2 = 37.26; P = 0.00 and PUJAM: Chi2 = 81.82; P = 0.00). Estos datos refuerzan la prioridad que tienen en las acciones de vigilancia y control, por la comunidad en sus respectivas viviendas.

          Abstract:Several illnesses of vectorial origin have a great medical and veterinary relevance, due to the adaptations developed by the species involved in their transmission. To support preventive programs with updated ecological information of A. aegypti populations, an entomological survey was carried out in three Health Areas of Camagüey, Cuba, during low and high rain seasons of 2013. For this, we assessed the type and number of positive containers, quantified larvae and pupae in positive containers, according to the container location in or outside the house. Both the container representativeness percentage and the pupal index by specific containers were calculated (PIsC). The total of houses as well as the positive habitual-use and non-disposable containers were compared among weather seasons, using the non parametric Chi2 test. The existent relationship between the total of positive houses and the habitual-use and non-disposable container was explored through the test of proportions hypothesis, with a level of significance of P ≤ 0.05. A. aegypti colonized 73 different types of containers, being habitual-use and non-disposable a 23.2 %. This number included 76 % of the positive containers. The greatest larvae collections were obtained in exterior water tanks and barrels, with important pupal production (PIsC = 3.04 and 1.75, respectively), and as well as significant differences towards the rainy season respect to positive houses (PUIA: Chi2 = 32.89; P = 0.00; PUE: Chi2 = 127.44; P = 0.00 and PUJAM: Chi2 = 127.44; P = 0.00), and the habitual-use and non-disposable container (PUIA: Chi2 = 30.37; P = 0.00; PUE: Chi2 = 37.26; P = 0.00 and PUJAM: Chi2 = 81.82; P = 0.00). These data reinforce the priority given to the control and surveillance actions conducted by the community in their respective houses. Rev. Biol. Trop. 64 (4): 1487-1493. Epub 2016 December 01.
