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.
Biological control of pest species by predators, parasitoids, and pathogens has been a cornerstone of IPM since its inception. It has been difficult to utilize the full potential of biological control in tree fruit and other crops that receive periodic sprays of broad-spectrum pesticides and/or have high quality standards.
Information to assist growers in selecting controls and timings for tree fruit insect and mite pests.
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.
