Insecticide resistance, associated mechanisms and fitness aspects in two Brazilian Stegomyia aegypti (= Aedes aegypti) populations

In the present study, a series of methodologies applied in the context of routine S. aegypti insecticide resistance monitoring programmes were used to characterize two Brazilian field populations, from Crato, in the state of Ceará (CE), and Aracaju, in the state of Sergipe (SE). In addition to profiles of resistance against the insecticides employed in the scope of the Brazilian dengue control programme, the participation of distinct resistance mechanisms was also investigated. Furthermore, different development and reproduction parameters were analysed in both populations in order to evaluate any potential correlation between these aspects and insecticide resistance.
