Summary: Synthetic chemical insecticides are widely used in population control of pests. Aedes aegypti is the primary vector of dengue, Zika, chikungunya and yellow fever to humans, and has proven resistance to chemical insecticides. As an alternative vector control method, the ethanolic extract of the leaves of Piper peltatum L. (Piperaceae) showed larvicidal activity against Ae. aegypti. Despite the wide medicinal use of this plant, the biological activity of its isolated constituents remains unexplored. In this sense, we isolated, identified and evaluated the larvicidal activity of 4-nerolidylcatechol (4-NC) from P. peltatum against Ae. aegypti, Culex quinquefasciatus and Anopheles darlingi, focusing on the larvicidal, adulticidal and genotoxic potential of 4-NC on Ae. aegypti.
