Herbivores have developed a series of mechanisms to deal with plant secondary metabolites. In order to understand plant-herbivore interactions, it is therefore essential to understand both the plant and the herbivore. We study how herbivores adapt to plant defense metabolites on a chemical and behavioral level. This work is carried out using the western corn rootworm Diabrotica virgifera as a model species.
