除虫菊酯

Pyrethrin

除虫菊酯是一种通常来源于菊花的天然有机化合物,具有很强的杀虫活性。 除虫菊酯是攻击所有昆虫的神经系统的神经毒素。 当以不对昆虫致命的量存在时,它们似乎具有驱虫效果。 除虫菊酯正在逐渐替代有机磷酸盐和有机氯化物作为首选农药。 它们不持久,可生物降解,并且在暴露于光或氧气的情况下分解。 除虫菊酯的化学结构启发了称为拟除虫菊酯的各种合成杀虫剂的生产,如联苯菊酯,氯菊酯和氯氰菊酯。 The pyrethrins are a pair of natural organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity. Pyrethrins are neurotoxins that attack the nervous systems of all insects. When present in amounts not fatal to insects, they still appear to have an insect repellent effect. Pyrethrins are gradually replacing organophosphates and organochlorides as the pesticide of first choice. They are not persistent, being biodegradable, and break down on exposure to light or oxygen. The chemical structure of pyrethrins inspired the production of a variety of synthetic insecticides called pyrethroids, such as bifenthrin, permethrin, and cypermethrin.
