This comprehensive handbook, acclaimed when it was first published in 1976 as one of the most useful reference manuals on diagnostic entomology yet produced, has now been completely revised and expanded to reflect recent advances in technology and the wealth of new information affecting the Green Industry. Augmented by 241 full-color plates, it gives the essential facts about more than 900 species of insects, mites, and other animals that injure woody ornamental plants in the United States and Canada, and provides means of quick visual identification of both the pests and the damage they cause.
