Book Description
Ce guide veut aider à l'identification des insectes et des acariens qui endommagent les arbres. Il traite d'environ 90 espèces de ravageurs qui ont causé des dégâts importants aux pins canadiens à l'est des montagnes Rocheuses. Des clés sous forme de diagramme permettent d'identifier l'insecte ou les dégâts qu'il cause, et cette identité peut être confirmée par quelque 190 illustrations en couleurs. La description biologique sommaire de chaque insecte ou acarien, souvent accompagnée d'information sur les besoins de lutte, est puisée en grande partie dans les Relevés des insectes et des maladies des arbres. Dans le cas o la lutte est nécessaire, les méthodes éventuelles sont proposées.

Book Description
This handbook is designed to enable people who are interested in trees to identify the insects and mites causing damage to them. About450 species of insects and mites that have caused noteworthy damage to hardwood trees in Canada east of the Rocky Mountains are included. Identification is based initially on the kind of tree damaged, and the insects are grouped under 20 tree genera. Within each host tree section, flow-chart keys, understandable to the layperson, are provided to lead the reader to individual species or groups of similar organisms, with full-colour illustrations to confirm the identity of the insect or mite. The accompanying biological sketch for each insect or mite usually includes information on the necessity for control, based largely on Forest Insect and Disease Survey records. Where control is necessary, methods are suggested. Common names of insects are also given in the text.
