CANIZALES, Cristian Camilo; CARRANZA, Julio César; VALLEJO, Gustavo Adolfo e URREA, Daniel Alfonso. Aedes albopictus distribution in Ibagué, Colombia: Potential risk of arboviral outbreaks. Biomed. [online]. 2023, vol.43, n.4, pp.506-519. Epub 01-Dez-2023. ISSN 0120-4157. https://doi.org/10.7705/biomedica.7010.
Introduction.
Aedes albopictus is a vector for arboviruses, such as dengue, Zika, chikungunya, and yellow fever. The first A. albopictus reports on the American continent date back to 1985. It has spread rapidly throughout Colombia since its first report in 1998 due to its ecological and physiological adaptation capability.
Objective.
To determine A. albopictus distribution in the 13 communes of Ibagué, Colombia.
Materials and methods.
Samples were collected between May and November 2022 in the 13 communes of Ibagué. Vacuum sampling and sweep-netting entomological nets were used in areas with abundant vegetation. The mosquitoes were transported to the Laboratorio de Investigaciones en Parasitología Tropical at the Universidad del Tolima for taxonomic determination.
Results.
We identified 708 A. albopictus specimens distributed throughout Ibague's 13 communes. The highest vector abundance occurred in communes 10, 11, 7, 8, 2, and 9; communes 3, 4, 5, 6, 12, and 13 had a relative abundance of around 3%, while commune 1 had 2% of relative abundance.
Conclusions.
Aedes albopictus is distributed throughout all the communes of Ibague. Its dispersion has probably been favored by this region's environmental and social conditions. We recommend annual monitoring of these vectors populations and molecular characterization of the found arboviruses. Ascertaining this mosquito's distribution throughout the city will enable focusing entomological control strategies and preventing future arbovirus outbreaks.
