Temporal genetic structure of major dengue vector Aedes aegypti from Manaus, Amazonas, Brazil.

摘要: In recent years, high levels of Aedes aegypti infestation and several dengue outbreaks with fatal outcome cases have been reported in Manaus, State Amazonas, Brazil. This situation made it important to understand the genetic structure gene flow patterns among populations this vector vital pieces information for their management development new control strategies. study, we used nine microsatellite loci examine effect seasonality on Ae. from four urban neighborhoods collected during two main rainy dry seasons. All were polymorphic eight samples seasons, a total 41 alleles. The analyses season revealed homogeneity extensive flow, result consistent abundance breeding sites vector. However, significantly structured, due reduction Ne (Praca 14 de Janeiro Cidade Nova) analyzed, was primary factor influencing season. Genetic bottleneck suggested that Manaus are being maintained continuously throughout year, seasonal rather than severe or extinction, corroborating previous reports. These findings extremely great importance designing strategies Manaus.
