RESUMEN
ABSTRACT Aedes albopictus is considered a potential vector of arboviruses in Colombia. Females and males naturally infected with dengue, Zika and chikungunya viruses have already been found in this country. We document the first record of Ae. albopictus in the Cordoba department, in North of Colombia. The finding was carried out during Ae. aegypti collection activities in the Ayapel, Montelibano, Planeta Rica, Pueblo Nuevo and Puerto Libertador municipalities. The entomological material was collected in water containers such as cement water tanks, tanks, bottles, tires, abandoned toilets, and plastic lids with natural water located in the intradomicile, peridomicile, and extra-domicile spaces of the homes. We collected 658 Ae. albopictus samples in the larva and pupa stages, and once these reached adulthood, we determined that 389 were female and 269 were male. This is the first record of the presence of Ae. albopictus in the Cordoba department.
RESUMEN
RESUMEN La estimación de los cambios en la diversidad y como se encuentran compuestas las comunidades de insectos en áreas de transmisión, de diferentes zonas de vida, puede indicar patrones diferenciales en la transmisión y fauna de reservorios asociada, así como diferentes escenarios de riesgo epidemiológico. Un ejemplo es la leishmaniasis, parasitosis relacionada con la presencia de flebotomíneos del género Lutzomyia, que en Córdoba (Colombia) presenta áreas de transmisión para las formas cutánea y visceral de leishmaniasis, enmarcadas en diferentes zonas de vida - Holdridge (Bs-T, Bh-T, entre otras). El presente estudio tiene como objetivo estimar la diversidad de los inventarios entomológicos realizados en diferentes zonas con presencia de potenciales vectores de leishmaniasis, en 17 localidades de diez municipios del departamento de Córdoba, entre mayo de 2015 y noviembre de 2016. En total se recolectaron 1695 flebotomíneos representado en 13 especies del género Lutzomyia. Las especies más abundantes para el departamento de Córdoba son Lutzomyia evansi y Lutzomyia gomezi, con el 30,44 % y 29,62 %, respectivamente. Se reporta por primera vez la presencia de Lutzomyia trapidoi para el territorio cordobés. Con este estudio se amplía el conocimiento de la diversidad del género Lutzomyia en términos de distribución de abundancias, diversidades verdaderas y composición de especies en zonas activas del departamento de Córdoba.
ABSTRACT The estimation of changes in the diversity and composition of insect communities in transmission areas belonging to different life zones, can indicate differential patterns in transmission and associated reservoir fauna, as well as different epidemiological risk scenarios. An example is leishmaniasis, a parasitosis related to the presence of phlebotomine sandflies of the Lutzomyia genus, which in Córdoba (Colombia) presents transmission areas for cutaneous and visceral forms of leishmaniasis, framed in different life zones - Holdridge (Bs-T, Bh-T, among others). The present study aims to estimate the diversity of entomological inventories carried out in different areas with presence of potential leishmaniasis vectors, in 17 localities of ten municipalities of the department of Córdoba, between May 2015 and November 2016. A total of 1695 phlebotomine sandflies represented in 13 species of the genus Lutzomyia were collected. The most abundant species for the department of Córdoba are Lutzomyia evansi and Lutzomyia gomezi, with 30.44 % and 29.62 %, respectively. The presence of Lutzomyia trapidoi is reported for the first time for the territory of Córdoba. With this study, the knowledge of the diversity of the genus Lutzomyia in terms of abundance distribution, true diversities and species composition in active zones of the department of Córdoba is expanded.
