The mosquito Aedes aegypti is the main Dengue vector in Latin America. This study investigated the genetic structure of this vector using samples collected in Venezuela, Colombia, Peru, Mexico, Argentina, Puerto Rico, and French Guiana. We examined the distribution of a 246-basepair region of the NADH dehydrogenase subunit 4 mitochondrial gene among a total of 369 Ae. aegypti from all the populations. This gene was amplified by the polymerase chain reaction and tested for variation using single strand conformation polymorphism analysis. Twelve haplotypes were detected among all the countries sampled and grouped into two clades. Significant differentiation was detected among the populations studied and these were not genetically isolated by distance.
