摘　　要：植物精油及化合物对登革热的主要媒介埃及伊蚊幼虫具有杀幼虫活性。从269种植物中提取的361个植物精油中,超过60%具有较高的生物活性(LC_(50)<100 mg/L),这些植物主要为桃金娘科、唇形科和芸香科。精油中富含苯丙烷类、倍半萜烯类和单萜烯类物质具有最高的活性。着重介绍了植物精油对埃及伊蚊幼虫的活性、影响精油的活性因素、分子结构与活性相关性及精油及化合物的作用机理。Essential oils and their compounds exhibit bioactivity against Aedes aegypti L. （Diptera： Culicidae） larvae, which is the primary vector of dengue. More than 60%of 361 essential oils from 269 plant species were considered active（LC50﹤100 mg/L）, and the majority of these active oils were derived from plant species belonging to Myrtaceae, Lamiaceae and Rutaceae. Essential oils rich in phenylpropanoids, oxygenated sesquiterpenes and monoterpene hydrocarbons were found to be the most active. This article mainly reviews activities of essential oils against A. aegypti larvae, the factors affecting activities of essential oils, structure-activity relationships of essential oil compounds and their mode of action.
