Avaliação da atividade larvicida do óleo essencial do Zingiber officinale Roscoe (Gengibre) frente ao mosquito Aedes aegypti

Abstract

This study analyzes the larvicidal effect of the oil of Zingiber officinale Roscoe against larvae in third stage of the mosquito Aedes aegypti (Linnaeus 1792). The essential oil was extracted quantitatively by hydrodistillation and we calculated the oil’s LC50from Reed-Muench (1938) and Pizzi (1950) methods, respectively. The essential oil obtained LC50of 76.07 (±2.24) ug mL-1, and yield of 0.52% m/v. The results indicate that the essential oil assessed has substances that provide larvicidal effect against Aedes aegypti.
