Populations of several species of mites of different trophic levels co-occur on the same plant individual. The interactions among these species can either be directly, i.e. through predation or interference competition, or indirectly, through interactions mediated by the plant or by a population of predators that attack several species. Examples of indirect interactions are resource competition, apparent competition, intraguild predation, and interactions through induced plant defences. This symposium will be on such interactions and their effect on behaviour and dynamics of the species involved.
