Abstract
Este trabalho foi apoiado pelo Conselho Nacional de Pesquisa (CNPq PRONEX-Rede Dengue 550116 / 2010-9, CNPq 590154 / 2011-7, CNPq 472491 / 2012-1), Fundação de Apoio à Pesquisa do Estado de Pernambuco (subvenção FACEPE-PPSUS APQ 1361-4.00 / 08) e Fundação Oswaldo Cruz / Vice-Presidência de Pesquisa e Laboratórios de Referência / Serviço de Referência para Controle de Culicídeos Vetores / Centro de Pesquisas Aggeu Magalhães-PE (FIOCRUZ / VPPLR / SRCCV / CPqAM-PE) . Aedes aegypti is the vector of dengue virus, and its control is essential to prevent disease transmission. Among the agents available to control this species, biolarvicides based on Bacillus thuringiensis serovar israelensis (Bti) are an effective alternative to replace the organophosphate temephos for controlling populations that display resistance to this insecticide. The major goal of this study was to determine the baseline susceptibility of Brazilian Ae. aegypti populations to Bti, taking into account their background in terms of larvicide exposure, status of temephos resistance and the level of activity of detoxifying enzymes involved in metabolic resistance to insecticides.
