Herbivore-induced plant defences influence the behaviour of insects associated with the plant. For biting-chewing herbivores the octadecanoid signal-transduction pathway has been suggested to play a key role in induced plant defence. To test this hypothesis in our plant-herbivore-parasitoid tritrophic system
