Predators and Parasitoids

Population size and the dynamic behaviour of many plant-eating insects is largely determined by the levels of their natural enemies. Any reduction in enemy number can result in an insect outbreak. Applied biological control can therefore be considered as a strategy to restore 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 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 reveals the latest research in this field. Ideal for graduate students, research scientists and professionals in biological pest control, agriculture, entomology and ecology.
