alpha-cypermethrin

Alpha-cypermethrin is a highly active synthetic Type II pyrethroid insecticide consisting of the two most biologically active stereoisomers of cypermethrin (the (1R,cis)-alpha-S and (1S,cis)-alpha-R enantiomers). It acts as a potent modulator of voltage-gated sodium channels in insect neurons, delaying channel inactivation and causing prolonged sodium influx, which leads to repetitive nerve firing, hyperexcitation, paralysis, and death. Originally developed by Shell International Chemical Company in the 1980s and later acquired/marketed by BASF, FMC, and other agrochemical companies, alpha-cypermethrin is widely used in agriculture to control chewing and sucking pests, in public health for vector control (such as indoor residual spraying and insecticide-treated nets for malaria prevention), and in veterinary medicine to control ectoparasites.
