Piperonyl butoxide has negligible toxicity in its own right at the doses used, inhibits metabolizing enzymes in insects and mammals, increasing the toxicity of pyrethrins and pyrethroids to target and nontarget species. In addition to the parent compound, major metabolites of bifenthrin detected in rat plasma were the hydrolysis product
The rats exhibited fine tremors, increased head shaking, pawing, elevated body temperature, increased
