Molecular population genetics of the primary neotropical malaria vector Anopheles darlingi using mtDNA.
Samples of the neotropical malaria vector Anopheles darlingi from Bolivia, Brazil, and Venezuela were analyzed to test for differences in mitochondrial haplotype frequencies. With the use of molecular variance components and F-statistics, significant genetic variability of An. darlingi was found apportioned primarily among populations within regions or within populations, with regions defined either as biomes (n = 5) or ecoregions (n = 2). The Mantel analysis resulted in a significant correlation [Prob (r) = 0.009] between genetic and geographic distances, evidence that these populations are genetically isolated by distance. Such isolation could reflect differences in phenotypes for factors affecting vector capacity.
