Summary

Insects are major pests of both natural and plantation forests in the tropics. This book is the first to provide a broad-based, international review of this subject at a level suitable for advanced students and practitioners. It describes the ecology and biology of the insects with special reference to the economic damage they cause to trees. All relevant control strategies are addressed.
