Methoxyfenozide-d9 is the deuterium labeled Methoxyfenozide[1]. Methoxyfenozide, a diacylhydrazine insecticide, selectively binds to lepidopteran ecdysone receptors (EcRs) over dipteran EcRs with Kd values of 0.5 and 124 nM, respectively. Methoxyfenozide is lethal to neonatal larvae of S. exigua, S. frugiperda, T. ni, O. nubilalis, L. pomonella, H. zea, and H. virescens (LC50s=0.35, 0.2, 0.11, 0.18, 0.21, 0.79, and 3.12 mg/L, respectively)[2]. | [References]
