Glucosinolates are amino-acid derived allelochemicals which are hydrolysed upon tissue damage by myrosinase enzymes to produce various degradation products which can be toxic for generalist insects. The larvae of the crucifer-specialist Athalia rosae, the turnip sawfly, sequester glucosinolates into their haemolymph. The role of the glucosinolate-myrosinase system for the interaction of the turnip sawfly with Brassicaceae was examined in this study from two different perspectives: variation within individual plants and between plant species. The plant responses to the feeding by herbivores and the short-term effects this induction had on insect behaviour were investigated in white mustard. Furthermore, plants can use multiple defences. Hence correlations of glucosinolates and myrosinase activities with other defences and nutritional quality and their long-term effects on the development of the insects were investigated in seven different plant species.}, subject = {Glucosinolate}, language = {en} }
