Omnivorous insects are ubiquitous yet difficult to incorporate into food web models, largely because they can function as herbivores or predators depending on how much plant vs. prey they consume. Plant traits, i.e. inducible responses, can mediate this trophic position by altering what, and how much, resources can be taken from the plant and thus how much prey must be consumed. Using a specialized system involving a native CA plant (Stachys bullata), a native herbivore (leafhopper sp.) and a native omnivore (Dicyphus hesperus), we will address the following questions: (1) Do herbivores and omnivores ellicit different plant responses?; (2) Can plants detect trophic shifts by an omnivores?; (3) Do plant responses favor plant, herbivore or omnivore performance?; (4) Do plant responses alter the trophic position of the omnivore?
