  自从1949年丙烯菊酯由美国Schechter被合成出来后,国内外掀起了开发拟除虫菊酯类农药的高潮,到目前为止国内登记的拟除虫菊酯类农药产品近80个,拟除虫菊酯类农药已经发展成为第二大杀虫剂品种,占全球杀虫剂市场的20%。拟除虫菊酯类农药具有用量低、药效好、杀虫谱广等优点,是我国提倡推广的一类广谱性农药,也是21世纪新农药开发的热点,被人们广泛应用在农林害虫、家用卫生、畜禽养殖、粮食储存等领域,近年来也被广泛用于渔业养殖中杀灭寄生虫和敌害生物。拟除虫菊酯类农药具有对环境稳定、降解速度慢和再加工降解率低等特点。研究表明,某些拟除虫菊酯具有雌激素活性,而且其代谢产物可能比母体化合物更易于与雌激素受体作用。
