When attacked by multiple herbivores, plants should be able to play a defence strategy that is the best solution to attack by this community rather than maximizing its defence to each individual attacker. This is because a defence response to one herbivore may make plants more susceptible to colonisation by other herbivores. Moreover, the physiological response to one herbivore may affect the capabilities of a plant to respond to the next herbivore. I study how plants deal with multi herbivore attack, what are their physiological limitations in response to multi attack and whether plant species differ in their solutions to defend themselves against their specific dynamic herbivore community.
