Insect hosts, life stages, life histories, damage, monitoring, biological control, and management are described for most major and minor pests in orchards as well as major natural enemies.

Homeowners who grow fruit in backyards or small orchards find that disease and insect pests often ruin the crop and in some instances damage the tree itself.

In some years it may be possible to grow acceptable fruit without the use of pesticides, but in most years a few well-timed insecticide and fungicide sprays are needed.
