Chemical Composition, Larvicidal Activity, and Enzyme Inhibition of the Essential Oil of Schauer from the Caatinga Biome against Dengue Vectors.

Insect resistance and environmental pollution are among the drawbacks of continuous use of synthetic insecticides against the vectors of dengue, and . The objective of this study was to analyze the composition of the essential oil of Schauer collected from plants, in three periods of the year, to compare the larvicidal activity and enzymatic inhibition of the dengue vectors. The oilsanalyzed by gas chromatography coupled to mass spectrometry (GC-MS), presented thymol and 1,8-cineole, as the main constituents, in all three periods.
