This study provides a modern synthesis of forest research ecology and control, drawing extensively on original research papers. It aims to give the reader an insight into the nature of forest pests by emphasizing the roles of climate, natural enemies, competition and interactions with the host tree in their population dynamics. By drawing attention to the ecological characteristics that determine the extent and frequency of outbreaks, and the impact they have on the forest and the forest environment, a basis is provided for a realistic appraisal of the value of silvicultural, biological, chemical and other control methods. The text examines how best to incorporate these methods into a framework of integrated pest management for particular pest species. The book is illustrated throughout with practical examples, and the subject matter should appeal to pure and applied biologists, ecologists and entomologists, as well as the more practical students of forest management.
