Avaliação da atividade larvicida do óleo essencial de Citrus latifólia (TANAKA) frente ao Aedes aegypti

Abstract

Dengue is a viral disease, transmitted by the Aedes aegypti mosquito, in addition to being the main vector of the Chikungunya and Zika viruses. No vaccine has been validated by Anvisa, therefore, the way to combat the proliferation of A. aegypti is through vector control. In this way, there is a need to develop new larvicidal products and, one of the alternatives, is the use of natural products. In this sense, the present work has the objective of evaluating the larvicidal action of the dry leaves of the species Citrus latifolia (TANAKA) against the larvae of the third state of the mosquito A. aegypti, under laboratory conditions. The bioassay was followed by the World Health Organizations with modifications in the test container and the extraction of the dry leaves was done through hydrodistillation in a Clevenger apparatus. The study concluded that the species C. latifolia presented CL50 = 197.93 μg.mL-1 against A. aegypti L3 larvae in 24 hours of exposure, showing to be moderately active.
