Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus

open access: yesChemistry &Biodiversity, EarlyView.
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (
