Ponderosa pine (Pinus ponderosa) is the most widely distributed conifer in North America, and one of the most valuable. Commercial stands of the species are found in all of the 15 States which lie wholly or in part west of the 102d merinian, and in all but one it rank among the most important lumber producers. In the Southwest, ponderosa pine is of particular importance since this one species makes up 88 percent of the standing saw-timber volume in the two States of Arizona and New Mexico.

This text considers forest insects occurring in forest ecosystems, specialized forestry settings, and urban forests, with an approach and coverage that make it suitable for use in both undergraduate and graduate courses in forest entomology and forest protection. Early chapters introduce entomology, middle chapters provide the first comprehensive treatment of the principles of Integrated Pest Management (IPM) of forest insects, and later chapters discuss the pest insects according to their feeding group.
