Abstract:

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES<br>Considered viral diseases of major re-emerging in the world, the dengue, chikungunya and Zika have as the main vector Aedes aegypti (L.) (Diptera: Culicidae). Larvicidal vector control is an important measure to prevent the transmission of such infections. A major challenge in the control of this arthropod is the low sensitivity of its population through the use of conventional larvicides. Thus, the insect acquires resistance, reducing the effectiveness of these pesticides. Consequently, it will lead to an increase in
