This study aimed to evaluate the chemical profile and larvicidal activity of essential oil (EO) extracted from the leaves of Pimenta dioica L. in front of the larvae of the Aedes aegypti mosquito. The EO was extracted by hydrodistillation, with chemical characterization through coupled Gas Chromatography and mass spectrometry (GC-MS). The physicochemical parameters were determined according to the methods described in the Brazilian Pharmacopoeia. The toxicity assay evaluated the lethality of EO against Aedes aegypti. CL50 was calculated for EO action against Aedes aegypti larvae using the...
