噻虫嗪是继吡虫啉之后,化学杀虫剂取得的又一项重要的新成就。它较吡虫啉有更高的生物活性,更高的安全性和更宽的活性谱,且与吡虫啉无交互抗性。本文根据近年国外的有关报道,对噻虫嗪作了较全面的概述。内容涉及历史背景、发现过程、合成反应、生物活性、结构-活性相关。田间表现、作用模式、理化性质、安全性能和环境行为等。 Thiamethoxam is another important new achievement made by chemical insecticides after imidacloprid. It has higher biological activity than imidacloprid, higher safety and broader spectrum of activity, and no interaction with imidacloprid. In this paper, according to foreign reports in recent years, thiamethoxam made a more comprehensive overview. Content related to the historical background, discovery process, synthesis reaction, biological activity, structure - activity related. Field performance, mode of action, physical and chemical properties, safety performance and environmental behavior.
