Aedes aegypti and Aedes albopictus are important vectors that transmit arboviruses to human populations.
Natural products were obtained and tested against larvae collected from the field in Fortaleza, capital of Ceará state.
The essential oils of Syzygium aromaticum (Ae. aegypti LC50 = 32.7 ppm and Ae. albopictus LC50 = 138.1 ppm) and Croton nepetaefolius (Ae. aegypti LC50 = 81.7 ppm and Ae. albopictus LC50 = 76.1 ppm) showed the most intense larvicidal activity.
The essential oils and methyl esters showed greater larvicidal activity than did the ethanol extracts.
埃及伊蚊和白纹伊蚊是将虫媒病毒传播给人类的重要病媒。
获取天然产物并针对从塞阿拉州首府福塔莱萨的野外采集的幼虫进行测试。
丁香（埃及伊蚊LC50 = 32.7 ppm，白纹伊蚊LC50 = 138.1 ppm）和猫须草（埃及伊蚊LC50 = 81.7 ppm，白纹伊蚊LC50 = 76.1 ppm）的精油表现出最强的杀幼虫活性。
精油和甲酯比乙醇提取物表现出更强的杀幼虫活性。
