Mosquitoes, known as one of the deadliest creatures on the planet, pose significant risks to the health of humans and animals worldwide by transmitting diseases like malaria, dengue, lymphatic filariasis, West Nile fever, and Zika virus. As mosquito-borne diseases continue to pose a significant threat to global public health, the development and enhancement of effective vector control strategies have become increasingly critical. Among the promising approaches is the use of insecticides such as imidacloprid, a systemic neonicotinoid known for its potent insecticidal properties.
This study aims to observe the larvicidal and pupicidal activity of Imidacloprid against Culex quinquefasciatus as per the guidelines of World Health Organisation (WHO). The mortality data were analysed for the determination of LC and LC.
In this study, the LC and LC values for Cx. quinquefasciatus larvae were determined to be 0.049 mL/L and 0.137 mL/L, while for pupae, the values were 0.264 mL/L and 0.480 mL/L respectively.
The obtained results signifies the considerable efficacy of Imidacloprid that could be used as a potential mosquitocide.
蚊子被认为是地球上最致命的生物之一，通过传播疟疾、登革热、淋巴丝虫病、西尼罗河热和寨卡病毒等疾病，对全球人类和动物的健康构成重大风险。由于蚊媒疾病继续对全球公共卫生构成重大威胁，开发和加强有效的病媒控制策略变得越来越关键。在有前景的方法中，包括使用杀虫剂，如吡虫啉，一种以其强大杀虫特性而闻名的内吸性新烟碱类杀虫剂。
本研究旨在按照世界卫生组织（WHO）的指南，观察吡虫啉对致倦库蚊的杀幼虫和杀蛹活性。分析死亡率数据以确定LC和LC。
在本研究中，致倦库蚊幼虫的LC和LC值分别确定为0.049 mL/L和0.137 mL/L，而蛹的LC和LC值分别为0.264 mL/L和0.480 mL/L。
获得的结果表明吡虫啉具有相当大的功效，可作为一种潜在的灭蚊剂。
