The insects presented in this book are among the most common and the most destructive found on what are considered to be the most important tree species; namely, spruce, larch, pine, oak, maple and poplar.It is intended for use by both scientists and by practising foresters. To make the information contained in this volume more easily accessible, insects are grouped according to the tree species that they attack rather than by their entomological classification, and, for this reason, insects found on a given tree species are presented in the same chapter. The annual reports of the Forest Insect and Disease Survey have provided most of the information on history of outbreaks that is found in the text.
