Mosquitoes are vectors of pathogens to humans and domestic animals and may also have economical impacts. One approach to prevent mosquito-borne diseases is bite deterrence through the application of repellents. Currently, there is an interest to search for alternative bioactive products to the synthetic active ingredients most widely used in insect repellents. Repellence against Aedes aegypti of essential oils extracted from Acantholippia salsoloides, Aloysia catamarcensis, Aloysia polystachya, Lippia integrifolia, Lippia junelliana (Verbenaceae), Baccharis salicifolia, Euphatorium buniifolium, and Tagetes filifolia (Asteraceae) were assessed. Tests were conducted by alternatively exposing untreated and treated forehand to the mosquitoes and counting probing attempts. All essential oils tested were significantly repellent against A. aegypti when compared to untreated controls; L. junelliana was the most repellent and T. filifolia was the least based on the response of the mosquitoes to different concentrations of the essential oils (EO). Repellence may be attributed to the respective main components of each EO.
蚊子是人类和家养动物病原体的载体，也可能产生经济影响。预防蚊媒疾病的一种方法是通过使用驱避剂来防止蚊虫叮咬。目前，人们有兴趣寻找替代生物活性产品，以取代驱虫剂中最广泛使用的合成活性成分。从 Acantholippia salsoloides、Aloysia catamarcensis、Aloysia polystachya、Lippia integrifolia、Lippia junelliana（马鞭草科）、Baccharis salicifolia、Euphatorium buniifolium 和 Tagetes filifolia（菊科）中提取的精油对埃及伊蚊的驱避活性进行了评估。通过交替暴露未处理和处理过的前手来让蚊子接触，然后计算探测尝试次数来进行测试。与未处理的对照组相比，所有测试的精油对埃及伊蚊均有显著的驱避作用；L. junelliana 的驱避效果最强，而 T. filifolia 的驱避效果最弱，这是基于蚊子对不同浓度精油的反应。驱避作用可能归因于每个精油的各自主要成分。
