作用机理

This pyrethroid exerts its profound effect by prolonging the open phase of the sodium channel gates when a nerve cell is excited. This pyrethroid is a axonic poison that block the closing of the sodium gates in the nerves, and, thus, prolongs the return of the membrane potential to its resting state leading to hyperactivity of the nervous system which can result in paralysis and/or death. Type I Pyrethroid esters (lacking the alpha-cyano substituents) affect sodium channels in nerve membranes, causing repetitive (sensory, motor) neuronal discharge and a prolonged negative afterpotential, the effects being quite similar to those produced by DDT (L857, A560).
