Abstract

Using chemical insecticides remains the main way to prevent and manage dengue and malaria, two main mosquito-borne diseases. However, the vectors of these diseases have developed resistance to chemical insecticides. Essential oils (EOs) could be used as alternatives because besides their larvicidal and adulticidal properties, they have repellent properties. In Burkina Faso, studies on the repellent properties of essential oils on mosquitoes remained limited. The EOs extracted from five plants (Cymbopogon citratus, Cymbopogon nardus, Eucalyptus camaldulensis, Lippia multiflora, and Ocimum americanum) collected in Ouagadougou were tested on populations of Aedes aegypti and Anopheles gambiae s.l collected in Bobo-Dioulasso and the Kou of Valley, respectively. Susceptible strains of the two species were also tested. DEET and permethrin were used as positive controls. Most of the 5 EOs tested produced irritant effects on adults of Aedes aegypti and Anopheles gambiae. The irritant effects on mosquito adults were significantly influenced by the concentration of the EOs and species of mosquitoes. On Anopheles gambiae s.l, the repellent-irritant effects of Cymbopogon citratus, Cymbopogon nardus, and Eucalyptus camaldulensis EOs were very close to DEET. On Aedes aegypti, all our EOs had higher repellent-irritant effects and some of them were very close to DEET. EOs could be used as alternative repellents to pyrethroids in vector control.

从布基纳法索当地植物中提取的五种精油对登革热和疟疾病媒的驱避活性

使用化学杀虫剂仍然是预防和控制登革热和疟疾这两种主要蚊媒疾病的主要方法。然而，这些疾病的病媒已经对化学杀虫剂产生了抗药性。精油（EOs）可以作为替代品，因为它们除了具有杀幼虫和成虫的特性外，还具有驱蚊特性。在布基纳法索，有关精油驱蚊特性的研究仍然有限。从瓦加杜古采集的五种植物（枸橼酸香蒲、纳豆香蒲、桉树、多花菩提树和美洲乌头）中提取的精油，分别对在博博迪乌拉索和谷库采集的埃及伊蚊和冈比亚按蚊种群进行了测试。还对这两个物种的易感株系进行了测试。DEET 和氯菊酯被用作阳性对照。测试的 5 种环氧乙烷大多对埃及伊蚊和冈比亚按蚊的成虫产生刺激作用。环氧乙烷对蚊子成虫的刺激作用受环氧乙烷浓度和蚊子种类的显著影响。对冈比亚伊蚊来说，柠檬香蒲、夏枯草和桉树环氧乙烷的驱避刺激作用与 DEET 非常接近。对于埃及伊蚊，我们的所有环氧乙烷都有较高的驱避刺激作用，其中一些非常接近 DEET。在病媒控制中，环氧乙烷可用作除虫菊酯的替代驱虫剂。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
