八十年代初,Engel,Huff等分别用CF_3(C1)C=CH-基团代替天然菊酸(CH_3)_2C=CH(?)COOH中(CH_3)_2C=CH-基团,合成了性能极为优异的氟氯氰菊酯——Cyha-lothrin(α-氰基-3-苯氧基苄基-cis-(Z-2’-氯-3＇,3＇3＇-三氟丙烯基)-2,2-二甲基环丙烷羧酸酯)。防治它对多种害虫,抗性昆虫,螨类有良好的效果,对益虫毒性低,是一种理想的新品种。近年来,国外开发Cyhalothrin的酸组分的研究较为活跃,力求找到更有效杀虫、杀螨
In the early 1980s, Engel and Huff et al. Respectively replaced the (CH_3) _2C = CH- group of (CH_3) _2C = CH (?) COOH with CF_3 Excellent cyfluthrin-Cyha-lothrin (α-Cyano-3-phenoxybenzyl-cis- (Z-2’-chloro-3 ’, 3’3’-trifluoropropenyl) - dimethyl cyclopropanecarboxylate). Its prevention and control is good for many pests, resistant insects and mites, and has low toxicity to beneficial insects. It is an ideal new variety. In recent years, foreign research on the development of acid component of Cyhalothrin more active, and strive to find more effective insecticide, miticide
