Abstract
The role of plant-mediated constraints to herbivore populations in terrestrial ecosystems remains relatively poorly understood. One aim of this study was therefore to explore the effects of low host plant nitrogen (N) content on herbivore performance and feeding behaviour, and thereby to evaluate the utility of the N limitation and nutrient balance concepts. The grass-feeding grasshopper Omocestus viridulus (Orthoptera: Acrididae) provided a well-suited model system as the species exhibits high tissue N demands (11.3 % N dw) compared to other herbivores, and uses a relatively poor food source in the wild (median N content: 2.2 % dw). Using N-poor soil and fertil...
