(±)-Indoxacarb is a broad-spectrum oxadiazine insecticide.1 It is metabolized in vivo to its active N-decarbomethoxyllated metabolite DCJW. Topical administration of (±)-indoxacarb is lethal to S. frugiperda, H. virescens, L. lineolaris, N. cincticeps, N. lugens, L. decemlineata, A. grandis, and M. domestica (LD50s = 0.03, 0.44, 1.6, 0.72, >7.8, 2.81, 6.45, and 15 ng/mg, respectively). It suppresses voltage-gated sodium channel currents in rat dorsal root ganglion neurons in a concentration-dependent manner.2 Formulations containing (±)-indoxacarb have been used to control various insect pests in tea farming.3
