摘要

目的：蚊子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，制定和加强有效的病媒控制战略变得越来越重要。有希望的方法之一是使用杀虫剂，如吡虫啉，一种以其强效杀虫特性而闻名的系统性新烟碱类。方法：按照世界卫生组织（WHO）的指导方针，观察吡虫啉对致倦库蚊的杀幼虫和杀蚊活性。分析死亡率资料，测定LC50和LC90。结果：在本研究中，Cx的LC50和LC90值。致倦库蚊幼虫浓度分别为0.049 mL/L和0.137 mL/L，蛹浓度分别为0.264 mL/L和0.480 mL/L。结论：吡虫啉具有较好的杀蚊效果，可作为一种潜在的杀蚊剂。

Larvicidal and Pupicidal Activity of Neonicotinoid Insecticide Imidacloprid against Southern House Mosquito, Culex Quinquefasciatus (Say) (Diptera: Culicidae)

Purpose

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.

Methods

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 LC₅₀ and LC₉₀.

Results

In this study, the LC₅₀ and LC₉₀ 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.

Conclusion

The obtained results signifies the considerable efficacy of Imidacloprid that could be used as a potential mosquitocide.

期刊介绍： Acta Parasitologica is an international journal covering the latest advances in the subject. Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews. The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
