Larvicidal effect of essential oils of medicinal plants against larvae of Aedes aegypti L. (Diptera: Culicidae)
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 2
Abstract
Aedes aegypti L. is the most relevant mosquito in terms of public health importance of the world, because it’s the virus transmitter that causes many diseases, among this dengue. Looking for alternatives larvicides, the essential oils extracted from medicinal plants have demonstrated high efficiency. Thereby, it was objectified in this work to evaluate the larvicide potential of some essential oils, extracted from medicinal species, against A. aegypti larvae. The experiment was realized at the Laboratory of Products Technology and Agricultural Entomology of the Federal University of Cariri (UFCA), in city of Crato, CE. The essential oils alfazema (Hyptis suaveolens); gonçalo-alves (Astronium fraxinifolium0; alecrim de tabuleiro (Lippia Microphylla); mussambê (Cleome spinosa); marmeleiro (Croton sonderianus); aroeira (Myracrodruon urundeuva); velame (Croton heliotropiifolius) e candeeiro (Vanillosmopsis arborea) was extracted by hydrodistillation method in apparatus like Clevenger type. The oils were emulsified with dimethyl sulfoxide 2% (DMSO) and diluted to a concentration of 100 ppm (parts per million), utilizing design completely randomized with nine treatments (that consisted in the solutions of 100 ppm of each oil plus control solution with water and DMSO) and four repetitions, utilizing ten larvae for each treatment, being evaluated the number of dead larvae. Was calculated the mortality average by Tukey test with 5% of probability and the efficiency. It was observed that all the essential oils presented larvicide effect, but candeeiro and alfazema was the ones which was highlighted.
