Insects, Mites, and Beneficials
Alphabetically arranged fact sheets of insect and mite pests of apple, pear, peach, plum, and cherry.
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.
European honey bees are the primary managed pollinators in orchards because their abundance can be managed from year to year. However, due to competing demands, disease, the introduction of parasitic mites (mainly Varroa destructor), and likely impacts from insecticide and fungicide use in the field, the pollination picture has changed.
