爱福丁又称齐螨素，是阿佛曼链霉菌经二步发酵法加工提取等新工艺生产的抗生素类杀虫剂。其杀灭害虫的机理是通过剩檄虫体使Y－氨基丁酸释放加强，从而阻断运动神经信号的传递过程，而干扰害虫神经生理活动，使虫体麻痹，不能行动、取食，2～4天后死亡。该制剂具有广谱性，既对
Ai Fuding, also known as acaroid mites, is a kind of antibiotic insecticide produced by Avermectin Streptomyces by two-step fermentation process. The mechanism of killing pests is to release the Y-aminobutyric acid by means of leftover worms so as to block the transmission process of motor nerve signals and interfere with the neurophysiological activities of the pests to paralyze the insects, ~ 4 days after death. The preparation has a broad spectrum, both
