Population genetic structure of the dengue mosquito Aedes aegypti in Venezuela

Insecticide resistance and genetic variability in natural populations of Aedes (Stegomyia) aegypti (Diptera: Culicidae) from Colombia

“…This pattern is in agreement with previous studies (GORROCHOTEGUI-ESCALANTE 2002, BOSIO et al 2005, HERRERA et al 2006, BRACCO et al 2007, PADUAN & RIBOLA 2008. The haplotypes found in this study indicate a relationship between the Mexican and North American populations.…”

“…The studied Colombian A. aegypti populations were genetically structured, a trend also found in other populations from South America and Central America (GORROCHOTEGUI-ESCALANTE et al 2002, COSTA-DA-SILVA et al 2005, URDANETA-MARQUEZ et al 2008, PAUPY et al 2012, TWERDOCHLIB et al 2012, CALDERA et al 2013. The genetic structure of the studied Colombian populations occurred between regions separated by less than 17 km, similar to the patterns observed in Venezuela (distance less than 15 km between them), which suggest that gene flow is restricted (HERRERA et al 2006). Geographic barriers associated with Andean mountains in the state of Quindío probably obstruct gene flow.…”

“…Low genetic diversity is most likely a result of a decline in population size caused by insecticide use, as it was observed in vector populations from Trinidad and Tobago, and Venezuela (YAN et al 1998, HERRERA et al 2006. However, some studies have revealed the presence of greater genetic diversity in areas that are frequently treated with insecticides, as shown for A. aegypti populations from French Polynesia and Brazil (PAUPY et al 2000, AYRES et al 2004).…”

Genetic variability of Aedes aegypti in the Americas using a mitochondrial gene: evidence of multiple introductions

“…aegypti from Venezuela and Peru, using the same fragment of the ND4 gene and MP analyses, generated two clusters (da Costada-Silva et al 2005, Herrera et al 2006). Moreover, in both studies, the results of the AMOVA demonstrated the major component of variation to be within population.…”

Phylogeography of Aedes aegypti (Yellow Fever Mosquito) in South Florida: mtDNA Evidence for Human-Aided Dispersal

“…aegypti 11,[24][25][26][27][28][29][30] and other mosquitoes 23,31,32 showed variability in the ND4 and ND5 sequences that yielded reliable gene genealogies suitable for inferring population structure and contributions of historical and current demographic processes. Both forward and reverse strands were sequenced using the ABI 3100 automated sequencer at the Keck Center, University of Illinois, Urbana-Champaign, IL.…”
