The Conservation of Insects and their Habitats is a compilation of papers presented in the 15th Symposium of the Royal Entomological Society of London held at the Department of Physics Lecture Theatre Imperial College, London, on September 14-15, 1989. The papers cover topics on the diversity of entomological habitats and ecologicalroles around the world, and highlight the value of insects to humanity. Some practical proposals for conservation, especially in tropical forests and on islands, where their diversity is greatest, are also given. This book will add to the continuing force for the conservation and protection of biological diversity of the Earth.
