The PhD student will investigate how induction and suppression of plant defence affect the food web of organisms inhabiting the plant and the community structure of plant-inhabiting arthropods. This entails studying the role of interspecific competition among herbivores and the role of predation. Specific questions are whether other herbivores can benefit from the reduced direct defence of plants attacked by the defence-suppressing spider mite and whether this reduced direct defence affects indirect plant defences through natural enemies. A large part of the research will consist of field experiments, carried out at the Federal University of Viçosa, Minas Gerais, Brazil.Closing date: 20 June 2012.
