Aedes aegypti is the main vector of dengue, Chikungunya and Zika virusworldwide. The strategies for the population control involve the use ofsynthetic insecticides, which may cause toxicity problems and environmentalcontamination. This study evaluated the larvicide effect of hydroalcoholicextracts of leaves and fruits Ilex paraguariensis and Ilex theezans onA. aegypti. The bioassays were conducted under controlled conditions. Freshand dry fruits of I. paraguariensis showed the higher larvicidal activity onA. aegypti than the leaves of the same species. Mosquito larvae showedincreased susceptibility from dried leaf extracts, fresh fruit and leaf ofI. theezans. It was also observed a variation in larval mortality during periodsof exposure. The larvicide efficiency of I. theezans extracts on A. aegypti arepromising results and widen the possibility for further studies of the use ofextracts of this plant.
