Mitochondrial DNA detects a complex evolutionary history with pleistocene epoch...

Cryptic species and lineages characterize Anopheles nuneztovari s.l. Gabaldón, an important malaria vector in South America. We investigated the phylogeographic structure across the range of this species with cytochrome oxidase subunit I ( COI ) mitochondrial DNA sequences to estimate the number of clades and levels of divergence. Bayesian and maximum- likelihood phylogenetic analyses detected four groups distr...

Evidence of two lineages of the dengue vector Aedes aegypti in the Brazilian Am...

Genetic variation was estimated in ten samples populations of Aedes aegypti from the Brazilian Amazon, by using a 380 bp fragment of the mitochocondrial NADH dehydrogenase subunit 4 (ND4) gene. A total of 123 individuals were analyzed, whereby 13 haplotypes were found. Mean genetic diversity was slightly high (h = 0.666 ± 0.029; π = 0.0115 ± 0.0010). Two AMOVA analyses indicated that most of the variation (∼70%...

Allozyme differentiation among allopatric populations of Anopheles nuneztovari ...

Four enzymes in six geographic populations, four Brazilian and two Colombian, of Anopheles nuneztovari were studied. There were differences among the most frequent alleles in the EST5, ACON and MDH loci in the populations from Brazil and Colombia. The α-GPD(*)C allele was encountered very frequently in the Palo/Sit population in Colombia and the α-GPD(*)B allele was found to be fixed in most of the Brazilian po...

Population genetic structure of the major malaria vector Anopheles darlingi (Di...

The population genetic structure of Anopheles darlingi, the major human malaria vector in the Neotropics, was examined using seven microsatellite loci from nine localities in central and western Amazonian Brazil. High levels of genetic variability were detected (5-25 alleles per locus; HE = 0.519-0.949). There was deviation from Hardy-Weinberg Equilibrium for 59.79% of the tests due to heterozygote deficits, wh...

Isozyme variation in four species of the Simulium perflavum species group (Dipt...

Electrophoretic studies of isozymes were done with four closely related species of the Simulium perflavum species group (Diptera: Simuliidade) in the Brazilian Amazon, using last-instar larvae collected in the field. Ten enzymes were studied, which yielded 11 loci. Diagnostic loci were not found between Simulium maroniense cytotype D and Simulium rorotaense. Simulium maroniense and S. rorotaense differed from S...
