Desulfation followed by sulfation: Metabolism of benzylglucosinolate in Athalia rosae (Hymenoptera: Tenthredinidae)
The sawfly species Athalia rosae (L.) (Hymenoptera: Tenthredinidae) is phytophagous on plants of the family Brassicaceae and thus needs to cope with the plant defence, the glucosinolate-myrosinase system. The larvae sequester glucosinolates in their haemolymph. We investigated how these compounds are metabolized by this specialist. When larvae were fed with ([ 14C]-labelled) benzylglucosinolate, o
