Etoxazole is an organofluorine acaricide.^1,2It induces toxicity in two-spotted spider mite (T. urticae) larvae (LC₅₀= 0.036 mg/L for the London reference strain) through inhibition of chitin synthase 1. It reduces acetylcholinesterase (AChE) activity in the freshwater fishO. niloticusin a concentration-dependent manner.³Etoxazole (2.2-22 mg/kg per day) inhibits the activity of catalase, glutathione peroxidase (GPX), and AChE in the liver and kidneys of rats in a dose-dependent manner.²Formulations containing etoxazole have been used for the control of mites in agriculture.
