几丁质是组成昆虫表皮的主要成分,在昆虫的外骨骼中起着至关重要的作用。Wellinga等在筛选除草剂敌草腈的过程中,偶然发现了能抑制昆虫几丁质合成的苯甲酰脲类化合物,合成了第1个具有杀虫作用的毒虫脲后,这一领域发展速度很快,一度被许多国外农药公司列为重点研究对象,实用和商品化的品种不断出现,并很快在农林害虫防治中得到应用。噻二嗪类噻嗪酮是由日本
Chitin is the main component of the insect epidermis and plays a crucial role in the insect’s exoskeleton. Wellinga et al. In the process of screening the herbicide dichitronitrile, benzoylurea compounds that inhibit the synthesis of insect chitin were accidentally discovered. After the first insecticide-forming raceme urea was synthesized, the speed of development in this area Soon, many foreign pesticide companies were once listed as the focus of research, practical and commercial varieties continue to emerge, and soon be applied in agricultural and forestry pest control. Thiadiazine Buprofezin is made in Japan
