Abstract:The metabolic fate of chlorpyrifos by normal and defaunated Coptotermes formosanus Shiraki was determined. The metabolites of [14C]ch1orpyrifos were identified by thin-layer chromatography and autoradiography and confirmed by gas-liquid chromatography. The major metabolite isolated from both normal and defaunated termites was 3,5,6-trichloro-2-pyridinol. Other metabolites recovered included O,O-diethy1 0- 3,5,6-trichloro-2-pyridyl phosphate, O,O-diethy1 0-3,6-dichloro-2-pyridyl phosphorothioate, and several unidentified polar compounds. An unidentified metabolite found in substantial amounts in the normal but absent in the defaunated termites was probably a conjugate of trichloro-2-pyridinol which could have been produced by the intestinal flagellates.
