 en Higher genetic variation estimated by microsatellites compared to isoenzyme markers in Aedes aegypti check for this species in other resources from Rio de Janeiro
Magda Clara Vieira da Costa-Ribeiro; Ricardo Lourenço-de-Oliveira & Anna-Bella Failloux


Aedes aegypti check for this species in other resources populations from five districts in Rio de Janeiro were analyzed using five microsatellites and six isoenzyme markers, to assess the amount of variation and patterns of gene flow at local levels. Microsatellite loci were polymorphic enough to detect genetic differentiation of populations collected at small geographic scales (e.g. within a city). Ae. aegypti populations were highly differentiated as well in the city center as in the outskirt. Thus, dengue virus propagation by mosquitoes could be as efficient in the urban area as in the outskirt of Rio de Janeiro, the main entry point of dengue in Brazil.
