20世纪80年代合成了一类具有很强的内吸性及持效性,并具有神经毒性的新烟碱类杀虫剂。它们通过与乙酰胆碱受体结合,从而阻断神经冲动传导而发挥作用。这种功能模式可以控制昆虫破坏根茎以及取食植物地上部分的行为。新烟碱类药剂通过触杀作用,特别适用于防治咀嚼式和刺吸式口器的昆虫。由于其具有较强的内吸传导性,也可以拌种防治地下害虫。新烟碱类杀虫剂防治谱非常广泛, In the 1980s, a group of neonicotinoid insecticides with strong internal absorption and persistence and neurotoxicity were synthesized. They act by blocking acetylcholine receptors, blocking the conduction of nerve impulses. This mode of functioning controls the insects’ disruption of the rhizomes and feeding on the plant’s aerial parts. Neonicotinoids through contact with the role of killing, especially for the prevention and treatment of chewing and sucking mouthparts insects. Because of its strong internal absorption conductivity, you can also seed dressing to control underground pests. Neonicotinoid insecticides control spectrum is very wide,
