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 Aedes aegypti mosquito. EO was extracted by hydrodistillation, with chemical characterization by coupled gas chromatography and mass spectrometry (GC-MS). Physicochemical parameters were determined according to the methods described in the Brazilian Pharmacopoeia. The toxicity test...
