"If you are a professional or amateur horticulturalist working with ornamental trees and shrubs, you will want this book. It is the most useful tool we have ever seen for identifying insects that affect woody plants. . . . For those times when you can't quite place the insect into a group there's a carefully done index according to host plant."—Horticulture Review
