ABSTRACT

RESUMO Este trabalho analisa o efeito larvicida do óleo Zingiber officinale Roscoe contra larvas em terceiro estágio do mosquito Aedes aegypti. Extraiu-se quantitativamente o óleo essencial por hidrodestilação e calculou-se a CL50 do óleo, a partir dos métodos de Reed-Muench e Pizzi, respectivamente. O óleo essencial obteve CL50 de 76,07 (±2,24) μg mL-1 e rendimento de 0,52% m/v. Os resultados indicam que o óleo essencial avaliado é composto por substâncias que propiciam efeito larvicida contra 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 LC50 from Reed-Muench (1938) and Pizzi (1950) methods, respectively. The essential oil obtained LC50 of 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.
