The oxidative metabolites produced from P32-fenthion by Cutex pipiens quinquefasciatusSay larvae were fenoxon sulfoxide and fenoxon sulfoxide which were found in the larval bodies, and fenthion sulfoxide and fenoxon sulfoxide which were found in the exposure water. Fenoxon was present only when the larvae were exposed to high concentrations of fenthion. The hydrolytic metabolites found in the larval bodies were dimethyl phosphorothioic acid and dimethyl phosphoric acid. The former water-soluble compound was the most abundant of all the metabolites, thus demonstrating the importance of thrones-type hydrolysis in the defoliation of fenthion by normal strains of C. p. quinquefascialus.
