研究了5种植物精油（波旁天竺葵、雪松、薄荷、百里香）不同浓度（5%、10%、25%、50%、75%、100%）及其复配对埃及伊蚊（Aedesaegypti（L.）和白曼按蚊Wiedemann应用于人类皮肤时，在实验室测试中确定。雪松油不能驱蚊，只有高浓度的薄荷油才能驱蚊。埃及人。当以5%或10%的浓度使用时，测试的油都不能防止蚊子叮咬。百里香和鸽子油是最有效的驱蚊剂，并提供11/2至31/2小时的保护，这取决于油的浓度。丁香油（50%）与天竺葵油（50%）或百里香油（50%）相结合，防止叮咬安。白化病11/4至21/2小时。使用精油作为局部驱蚊剂的可能性可能受到用户可接受性的限制;鸽子油、百里香油和薄荷油可能对皮肤有刺激性，而本研究中的两名人类受试者都认为在浓度大于或等于25%时，麝香草油和百里香油的气味不可接受。
The repellency of different concentrations (5, 10, 25, 50, 75, and 100%) and combinations of 5 essential oils (Bourbon geranium, cedarwood, clove, peppermint, and thyme) to Aedes aegypti (L.) and Anopheles albimanus Wiedemann when applied to human skin was determined in laboratory tests. Cedarwood oil failed to repel mosquitoes and only high concentrations of peppermint oil repelled Ae. aegypti. None of the oils tested prevented mosquito bite when used at the 5 or 10% concentration. Thyme and dove oils were the most effective mosquito repellents and provided 11/2 to 31/2 h of protection, depending on oil concentration. Clove oil (50%) combined with geranium oil (50%) or with thyme oil (50%) prevented biting by An. albimanus for 11/4 to 21/2 h. The potential for using essential oils as topical mosquito repellents may be limited by user acceptability; dove, thyme, and peppermint oils can be irritating to the skin, whereas both human subjects in this study judged the odor of clove and thyme oils unacceptable at concentrations greater than or equal to 25%.
