This study shows how to navigate the diversity of options presented in current ecological theory by developing the first general model of the entomological research requirements of Integrated Pest Management (IPM). The book includes practical advice on understanding and investigating species; examines the ecological problems associated with polyphagous pests and beneficial species; and scrutinizes ways suggested to improve insect biological control. It is an important resource for graduate students and researchers in IPM, insect pest management, entomology, ecology and crop protection.
