“…Two mitochondrial lineages were found in the populations evaluated, a pattern evidenced in prior studies (Bosio et al, 2005;Gonçalves et al, 2012;Aguirre-Obando et al, 2015;Monsalve et al, 2021). The haplotypes present in populations from Colombia and Mexico-North America and the bidirectional gene flow between these populations, suggested in our stepping-stone -1 model, could be supported by the presence of maritime routes between both countries, given that these have been associated with the global propagation of A. aegypti, bearing in mind population genetics studies conducted in maritime ports in Asia and Brazil (Paduan and Ribolla, 2008;Hlaing et al, 2010).…”

In Colombia Aedes aegypti is present in 80% of the country up to 2,300 m; however, little is known of its genetic relations within a country context and, hence, within a broader context, for example, America. The aforementioned, herein, analyzed the gene flow within a context of the Americas, its directionality and genetic diversity of the mitochondrial lineages in the A. aegypti populations for Colombia. This called for the use of the sequences for A. aegypti available of the mitochondrial ND4 gene in the GenBank for Colombia and the American continent. No presence was found of nuclear mitochondrial pseudogenes (NUMTs) for Colombia. It is estimated that in Colombia the gene flow of the A. aegypti populations is occurring from the southeast and northeast toward the center of the country. In comparison with the mitochondrial sequences for America, the vector's haplotypes in Colombia suggest connections between the populations of mosquitoes from the south with those from the north of the continent. The gene flow model at continental scale suggests bidirectional connections between the populations from the north of the continent with those from the south, while at South American scale it proposes the gene flow in all the directions with respect to the Colombian. The Colombian A. aegypti vector monitoring and control strategies must pay special attention to the vector's points of entry into Colombia related with Peru, Venezuela, Brazil, Mexico, and North America to avoid the entry of populations with characteristics like resistance to insecticides or vector competition.

“…3b). This hypothesis is supported by recent studies with microsatellites for three Colombian populations that evidence panmictic behavior (Monsalve et al, 2021). Consequently, the vector's dispersion toward the center of Colombia could occur through land or river communication routes.…”
