Chemical profile and larvicidal activity of anibaduckei kostermans essential oil

The control of Aedes aegypti encounters numerous difficulties and the most relevant point is the resistance that the mosquito has been presenting to the insecticides used in its control. Among the products alternative to synthetic insecticides, essential oils can be highlighted. Therefore, this work aims to evaluate the action of the chemical composition and larvicidal activity against Aedes aegypti of the essential oil extracted from the bark of the stem of the species Anibaduckei Kostermans. The essential oil was extracted by the hydrodistillation technique in a Clevenger apparatus. The chemical characterization of the essential oil was performed by gas chromatography coupled to a mass spectrometer (GC-MS). Toxicity was measured by the artemia saline lethality bioassay. The larvicidal activity against Aedes aegypti was performed through the techniques recommended by the Ministry of Health. The essential oil presented THE LC50 of 9.89 mg L-1, being classified as active, and non-toxic by the toxicity assay. It presented linalool as the majority component, being reaffirmed by the literature used. Finally, this oil has substances that provide and encourage its application due to its potential for biological activities.
