The uncontrolled increase in dengue and the resistance of Aedes aegypti to conventional insecticides have driven the search for sustainable alternatives. This research evaluated the larvicidal effect of ethanolic extracts from four species of the Ludwigia genus. It was found that Ludwigia octovalvis exhibited moderate larvicidal activity, with 70% mortality at 48 hours, surpassing the other species studied. These results support the use of plant extracts in vector control. Additional studies are needed to identify the active compounds, but L. octovalvis shows potential for the development of eco-friendly bioinsecticides
