The conjugation of phenols with phosphate in grass grubs and flies

Abstract
Houseflies, blowflies and New Zealand grass grubs were dosed with 1-naphthol, 2-naphthol or p-nitrophenol. The corresponding monoaryl phosphates were identified in extracts of insects or excreta along with the [beta]-glucosides and ethereal sulphates of the phenols. No diaryl phosphates or glucosidu-ronates were detected but an unidentified metabolite of [C14]l-naphthol was present in extracts of flies dosed with [C14]1-naphthol.
