Mosquitoes (Diptera: Culiciadae) potential vectors of arbovirus in the Urabá region, Northwest of Colombia Mosquitos (Díptera: Culicidae) vectores potenciales de arbovirus en la región de Urabá, noroccidente de Colombia

Introduction. Studies directed to investigate ecological parameters of sylvatic mosquitoes populations allows to establish the risk of arbovirus transmission and to bring recommendations for health authorities about prevention, surveillance and control. Objective. To establish the diversity and abundance of arbovirus mosquitoes vectors of in rural areas of Apartado and Turbo, Antioquia. Materials and methods. Quarterly sampling was done. For mosquito catching in forest fragments, CDC and Shannon traps was used, also human landing was used. Diversity and abundance indexes estimation was done. Results. 583 mosquitoes belonging to ten genera and 27 species were collected. The most abundant species were: Cq. venezuelensis (14.6%), Ae. scapularis (14.08%), Ps. ferox (10.82%) and Cx quinquefasciatus (10.3%). Specific richness and ecological indexes were highest in Turbo municipality; the fragment studied in Turbo is considered of most species richness and uniformity. The finding of Cx pedroi, Ae. scapularis, Ae. angustivittatus, Cq. venezuelensis, Cx. nigripalpus, Cx. quinquefasciatus, Cx. declarator, Ma. titillans, Ma. pseudotitillans, Ps. ferox y Tr. digitatum previously reported as arbovirus vectors warns about the possibility of transmission in the zone. Conclusions. Mosquito diversity and abundance in the study zone is high. The ecological analysis plus previous reports about vectorial capacity of some of the registered species allows us to conclude that arbovirus outbreaks in the area could be presented. Introducción. Estudios encaminados a conocer parámetros ecológicos de poblaciones de mosquitos selváticos, permiten establecer el riesgo de transmisión de arbovirus y aportar recomendaciones sobre prevención, vigilancia y control a las autoridades de salud. Objetivo. Determinar la diversidad y abundancia de mosquitos nocturnos y crepusculares, potenciales vectores de arbovirus en zonas rurales de Apartadó y Turbo, Antioquia. Materiales y métodos. Se realizaron muestreos trimestrales. Para la recolecta de mosquitos se usaron trampas CDC, Shannon y cebo humano protegido, en fragmentos de bosque entre las 18:00 y 06:00 horas. Se estimaron índices de diversidad y abundancia de especies. Resultados. Se capturaron 583 mosquitos, de 10 géneros y 27 especies. Las especies más abundantes fueron Cq. venezuelensis (14,6%), Ae. scapularis (14,08%), Ps. ferox (10,82%) y Cx quinquefasciatus (10,3%). La riqueza específica y los índices ecológicos calculados fueron mayores en Turbo; el fragmento de bosque estudiado en Turbo se considera de mayor riqueza y uniformidad d
