Abstract

ZAPATA-USUGA, Giovani et al. Presence of Aedes albopictus (Diptera: Culicidae) in some municipalities around of the Ituango Hydroelectric Project, Antioquia, Colombia. Actu Biol [online]. 2022, vol.44, n.116, e3.  Epub May 25, 2022. ISSN 0304-3584.  https://doi.org/10.17533/udea.acbi.v44n116a03.

In Colombia, there is still little knowledge about the distribution of Aedes albopictus, an arbovirus vector, in rural areas. Its introduction into the country was first recorded in Leticia (Amazonas) in 1998 and from there its distribution has been expanded. The objective of this study was to determine the presence of Ae. albopictus in rural areas of some municipalities of Antioquia. In an active search for entomological surveillance of Aedes aegypti in some municipalities of Antioquia that are part of the area of influence of the Ituango Hydroelectric Project, specimens of Ae. albopictus were collected in the indoor, around the inside and outdoor of houses using manual aspirators with protected human bait for adult mosquitoes; the search for immature stages was also carried out on natural and artificial breeding sites. Specimens were identified using dichotomous keys at the Entomology Laboratory of the Facultad Nacional de Salud Pública de la Universidad de Antioquia. A total of 110 individuals of Ae. albopictus were collected, - 55 larvae and 55 adults, respectively. The main breeding sites were the unusable ones. This finding is the first report in rural areas in eight municipalities of the department of Antioquia, which expands knowledge about the distribution of the Ae. albopictus vector and constitutes a potential risk in the emergence and transmission of diseases such as dengue, chikungunya and Zika.
