拟除虫菊酯是一类在天然除虫菊酯化学结构研究的基础上发展而来的仿生杀虫剂。这类杀虫剂的特点是击倒力强,杀虫作用快,广谱性,易降解,对高等动物及鸟类低毒性,不污染环境。1949年M.S.Schechter等合成第一种拟除虫菊酯——烯丙菊 Pyrethroids are a class of biomimetic insecticides that have evolved from the study of the chemical structure of natural pyrethrins. Such insecticides are characterized by strong knock-down, fast insecticidal action, broad spectrum, easy degradation, low toxicity to higher animals and birds and no pollution to the environment. In 1949, M.Schechter et al. Synthesized the first pyrethroid-acepropene
