Designed to introduce students and research workers to insect herbivore-host dynamics, this book uses the interaction between aphids and trees as a model. Challenging the belief that population dynamics of insect herbivores are heavily influenced by the action of their natural enemies, it demonstrates that tree dwelling species of aphids actually regulate their own population through competition for resources.
