Chapter synopsis: Mites are a perennial pest of tree fruit crops worldwide. Foliar feeding by mites can lead to decreased photosynthetic activity, reducing plant vigour and yield. For some mite pests, fruit deformation or russeting can occur. Two main families of mites are found on tree fruits: tetranychids (spider mites) and eriophyids (rust, bud and blister mites). This chapter reviews cultural and biological control tactics for controlling spider mites, including choosing tolerant varieties, weed management and releasing predators into orchards to increase their numbers and/or using management practices that conserve existing predator populations. The chapter describes the thresholds to determine when a spray application should be made and argues for biological control as the cornerstone of integrated mite management. Finally, the chapter includes guidance on further reading in this subject area.
