Population genetics and phylogeography of Aedes aegypti (Diptera: Culicidae) from Brazil
Population genetic analyses were conducted using samples of Aedes aegypti from 14 localities in the north, southeast, northeast, and central regions of Brazil. An 852-bp region of the mitochondrial DNA cytochrome oxidase I (COI) gene was used in the analyses. Ten haplotypes were observed, and cluste...

An 852-bp region of the mitochondrial DNA cytochrome oxidase I (COI) gene was used in the analyses.
