Knowledge of a pest's biology, including the stages at which it causes damage and its seasonal occurrence, and recognition of damage are essential to both conventional and alternative control methods in orchard pest management. This publication presents information on the damage symptoms and signs caused by many insect and mite pests commonly encountered in commercial as well as backyard apple orchards in the Midwest. A seasonal timeline shows the approximate time of occurrence for apple pests in central Missouri. This publication is part of a series of Integrated Pest Management manuals prepared by the MU Plant Protection Programs.
