Culex pipiens (Diptera: Culicidae) is one of the most prevalent mosquitoes particularly in the Al-Madinah Al-Munawwarah region, Kingdom of Saudi Arabia, transmitting numerous diseases such as arboviruses, avian malaria, elephantiasis, dirofilariasis, and encephalitis. Worldwide, Culex pipiens has developed resistance to numerous insecticides; therefore, considerable efforts have been done to introduce new mosquito control candidates. Due to their unique physical, biological, and eco-friendly properties, ionic liquids (ILs) have been recently considered as promising agents in controlling a variety of organisms. Six aminopyridinium-based ionic liquids (IL1–IL6) were assayed against eggs and pupae of C. pipiens. Percentages of non-hatched eggs, non-emerged pupae, the lethal concentrations (LC₅₀ and LC₉₀) of both C. pipiens eggs and pupae were recorded. after exposure, to different ILs. The effects of ILs against eggs and pupae were concentration and IL-dependant. The percentages of egg unhatchability were much higher than those of pupal mortality, as the percentage of egg unhatchability reached 99% after treatment with IL6 at 0.5 g/L, while the percentage of pupal mortality reached 40.8% after treatment with IL4 at 0.5 g/L. The LC₅₀ and LC₉₀ of ILs against pupae were much higher than those of ILs against eggs. Effects of ILs on Staphylococcus aureus (Bacillales: Staphylococcaceae) and Escherichia coli (Entrobacterales: Entrobacteriaceae) were also studied; some ILs showed a considerable effect on both bacteria species. This is the first study to show the ovicidal, pupicidal, and bactericidal effects of aminopyridinium-based ILs in controlling C. pipiens, S. aureus, and E. coli.

淡色库蚊（Dilexera：Culicidae）是最普遍的蚊子之一，特别是在沙特阿拉伯王国的Al-Madinah Al-Munawwarah地区，传播多种疾病，例如虫媒病毒，禽类疟疾，象皮病，铁丝虫病和脑炎。在全球范围内，淡色库蚊已经对多种杀虫剂产生了抗药性。因此，已经做了很大的努力来引入新的防蚊候选物。由于其独特的物理，生物学和环保特性，离子液体（IL）最近被认为是控制各种生物的有前途的药物。分析了六种基于氨基吡啶鎓的离子液体（IL1-IL6）对淡色梭菌的卵和p的影响。记录未孵化的卵，未出生的up的百分比，淡色梭菌卵和p的致死浓度（LC ₅₀和LC ₉₀）。暴露于不同的IL后。IL对卵和p的作用是浓度和IL依赖性的。用0.5 g / L的IL6处理后，鸡蛋的脱壳率要比99死亡率高得多，因为用0.5 g / L的IL6处理后，鸡蛋的脱壳率达到99％，而用0.5 g / L的IL4处理后，p的死亡率达到40.8％。 L. IL对against的LC ₅₀和LC ₉₀远高于IL对卵的IL ₅₀和LC ₉₀。白介素对金黄色葡萄球菌（Bacillales：Staphylococcaceae）和还研究了大肠杆菌（Entrobacterales：Entrobacteriaceae）。一些IL对这两种细菌都显示出相当大的影响。这是第一项显示基于氨基吡啶鎓的ILs在控制pipiens，金黄色葡萄球菌和大肠杆菌中的杀卵，杀螨和杀菌作用的第一项研究。
