Resumo: Dengue is an infectious disease transmitted by the bite of female Aedes aegypti during blood feeding, for continuity of the reproduction process. Population mosquito control has been carried out for decades, through the intensive use of conventional insecticides. The Bordeaux Mixture (BM) is a colloidal substance with insecticidal activity, bactericidal, fungicidal and molluscicide and can act comprehensively to control immature forms of A. aegypti, in addition to altering the physical and chemical conditions in the breeding and food chain insect. The values for the lethal concentrations of BM were CL10 1.05 mg L-1 (confidence interval 0.70 - 1.34), LC50 3.06 mg L-1 (2.73 - 3.35) and LC90 8.94 mg L-1 (7.42 - 11.92). The results of this study allow us to propose the BM as insecticidal potential for population control insect vectors.
