In Al-Madinah Al-Munawwarah region, Kingdom of Saudi Arabia, Culex pipiens is considered one of the most common mosquitoes. Owing to their exceptional chemical, physical, biological, and eco-friendly properties, ionic liquids (ILs) have been recently considered promising compounds in managing a variety of organisms. Six aminopyridinium-based IL derivatives were assessed to follow their efficacy against adults of C. pipiens. Mosquitoes were treated with aminopyridinium-based IL derivatives either orally or by spraying. It was observed in the first three days of treatment that the accumulated mortality rates were generally higher in sprayed mosquitoes with IL derivatives than their accumulated mortality rates in orally treated mosquitoes with the same ILs. It was also observed that the accumulated mortalities of sprayed mosquitoes at 0.125 and 0.25 g/L were higher than those in mosquitoes orally treated with the same concentrations. The highest mortality rates were 64 and 80% for sprayed and orally treated mosquitoes, respectively. The mode of action of aminopyridinium-based IL derivatives was tracked, and it is demonstrated to be through the digestive route for orally treated mosquitoes. This is the first study to show the adulticidal effects of aminopyridinium-based ILs in controlling C. pipiens.

在沙特阿拉伯王国的Al-Madinah Al-Munawwarah地区，淡淡库蚊被认为是最常见的蚊子之一。由于其优异的化学，物理，生物和生态友好特性，离子液体（IL）最近被认为在处理各种生物中很有前途。对六种基于氨基吡啶鎓的IL衍生物进行了评估，以了解它们对成年C.pipiens的功效。用基于氨基吡啶鎓的IL衍生物口服或喷雾治疗蚊子。在治疗的前三天观察到，用IL衍生物喷洒的蚊子的累积死亡率通常要比使用相同IL的口服蚊子的累积死亡率要高。还可以观察到，以0.125和0.25 g / L的剂量喷洒的蚊子的累积死亡率高于经相同浓度口服处理的蚊子的死亡率。喷雾和口服蚊子的最高死亡率分别为64％和80％。跟踪了基于氨基吡啶鎓的IL衍生物的作用方式，并证明它是通过口服途径处理的蚊子的消化途径。pipiens。
