ABSTRACT

Culex pipiens is the most abundant mosquito in Al-Madinah Al-Munawwarah region, Saudi Arabia, transmitting several diseases like elephantiasis, avian malaria, and arboviruses. It has become resistant to several insecticides worldwide, and the search for new alternatives should be prioritized. Because of their biological profile and eco-friendly nature, ionic liquids (ILs) have recently attracted the attention of biologists. The present study was carried out to evaluate the effect of six ILs against C. pipiens larvae. Larval mortality, LC₅₀, LC₉₀, LT₅₀ and residual activity of ILS were determined. Aqueous solutions of tested ILs showed up to 100% larval mortality 24 h after exposure. Significant concentration- and time-based differences in larval mortality were found for a given IL as well as between different ILs. Ultimately, the ILs tested in the current study could be arranged in descending order according to their toxicity against larvae as follows: IL7, IL5, IL4, IL1, IL2 and IL6.

摘要

淡色库蚊是沙特阿拉伯Al-Madinah Al-Munawwarah地区最丰富的蚊子，传播多种疾病，例如象皮病，禽类疟疾和虫媒病毒。它已对全世界的几种杀虫剂产生抗药性，因此应优先寻找新的替代品。由于其生物学特性和生态友好特性，离子液体（ILs）最近引起了生物学家的关注。进行本研究以评估六个IL对pipiens pipiens幼虫的作用。幼虫死亡率LC ₅₀，LC ₉₀，LT ₅₀测定ILS的残留活性。暴露后24小时，测试的IL的水溶液显示出高达100％的幼虫死亡率。对于给定的IL以及不同的IL之间，发现幼虫死亡率基于浓度和时间的显着差异。最终，在本研究中测试的ILs可以根据其对幼虫的毒性以降序排列，如下所示：IL7，IL5，IL4，IL1，IL2和IL6。
