Abstract: Aedes aegypti is the main vector of dengue, Chikungunya and Zika virus worldwide. The strategies for the population control involve the use of synthetic insecticides, which may cause toxicity problems and environmental contamination. This study evaluated the larvicide effect of hydroalcoholic extracts of leaves and fruits Ilex paraguariensis and Ilex theezans on A. aegypti. The bioassays were conducted under controlled conditions. Fresh and dry fruits of I. paraguariensis showed the higher larvicidal activity … Show more

“…israelensis (Bti), spread in the water of mosquito breeding places, has met the expected results, reaching mortality rates above 99% (Soares-da-Silva et al, 2017;Nakazawa et al, 2020). Additionally, during the last few years, plant-derived compounds have been extensively used as an alternative method for controlling mosquitoes, not only because this is a new insecticidal agent, but also because it has been described as being environmentally friendly (Gomes et al, 2016;Guarda et al, 2016;Knakiewicz et al, 2016;Rosa et al, 2016). The use of natural insecticides has some advantages over traditional synthetic products, because natural products are potentially less toxic to the environment.…”

“…It is an evergreen tree, early secondary or late secondary species (Souza, 2009), 20-m tall and 70-cm diameter, on average (Athayde et al, 1999). Both the I. paraguariensis fruit extract and the I. theezans hydroacoholic leaf extracts have larvicidal effect against A. aegypti larvae (Busato et al, 2015;Knakiewicz et al, 2016). Some studies showed that Ilex spp.…”

“…There are studies showing that Ilex spp. leaves and fruit extracts kill A. aegypti larvae within a 24h observational time[9,20]. However, there are no studies on the current literature evaluating the effects of time on the bioinsecticides lethal activity.…”
