The Identification Of Primary Red Pine Cone Insects

Excerpt from The Identification of Primary Red Pine Cone Insects Red pine (pinus resinosa Ait.) is one of the most important species used for reforestation in the Lake States. Because of the high cost and lack of control over genetic quality of commercially collected seed, the National Forest Administration has established seed-production areas in natural stands of trees with desirable lumber-producing characteristics. Since the objective is maximum production of high-quality seed, foresters are concerned with any agent that hinders this objective. One of the most destructive agents of cones and seeds is insects, despite the fact that damage is con fined to the second year of cone development (fig. This guide will familiarize the forester or nurseryman in the Lake States with the damage caused by insects to red pine cones, and enable him to recognize the mature larvae of the various spe cies and understand their relative importance.

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.
