This circular singles out some of the more important and troublesome insect pests of trees and shrubs in South Dakota. The insects are divided into groups based upon their feeding habits: sucking, leaf-chewing, gall producers, and those that attack stems, branches, and trunks. Proper application, applying, and storing of insecticides is also described.
