Insects, Mites, and Beneficials

Biology, monitoring and management of tree fruit insects and mites.

Regular field scouting and weather monitoring are key to achieving the production goals of conserving soil and water, reducing pesticide use, and being good, responsible employers. In this short video, you will learn some basic orchard scouting principles for a common disease – apple scab – and also mite pests and beneficials.

Alphabetically arranged fact sheets of insect and mite pests of apple, pear, peach, plum, and cherry. Life cycles are based on a “normal” year in south-central Pennsylvania. When dates are given, growers should make appropriate adjustments based on the difference in growing season for their region of the state. When the pest life cycle is based on the stage of the trees, generally no adjustments need to be made.

The modern approach to managing pests is referred to as integrated pest management (IPM). IPM involves compiling detailed, timely information about a crop and its pests to ensure that pest management decisions are economically, environmentally, and socially sound.

Information to assist growers in selecting controls and timings for tree fruit insect and mite pests.

Natural enemies and environmental factors limit populations of insect and mite pests in natural ecosystems. When natural enemies are killed by human’s actions in any habitat or when pests are introduced to new habitats without their natural enemies, natural control often fails and results in pest outbreaks.
