Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies in pest control as an integrated pest management concept. It examines how Trichogramma, the extensively studied natural enemy of insect pests, has been used as a pest management tool, and it describes important aspects such as the inducible defense mechanisms of plants and the effects that plant diversity can have on herbivores and natural enemies. Specific chapters address recent advances in biological control: the effects of multiparasitism on parasitization; synergism between insect pathogens and entomophagous insects; and the use of exotic insects for weed control. With contributions from leading worldwide experts, Predators and Parasitoids is ideal for graduate students, research scientists and professionals in biological pest control, agriculture, entomology and ecology.
