Biology, Injury, and Management of Maple Tree Pests in Nurseries and Urban Landscapes

Favored for their rapid growth and brilliant fall color, maple ( Acer spp.) trees are among the most commonly grown deciduous shade trees in urban landscapes and commercial production nurseries. Many maple species used as ornamental plants share a suite of important arthropod pests that have the potential to reduce the trees' economic and esthetic value. We review the biology, damage, and management for the most important pests of maples with emphasis on integrated pest management (IPM) tactics available for each pest. Unfortunately, the biology of some of these pests is not well studied. This knowledge gap, paired with the low esthetic threshold for damage on ornamental plants, has hindered development of IPM tactics for maple pests in nurseries and landscapes. Maples will likely remain a common landscape plant. Therefore, our challenge is to improve IPM of the diverse maple pest complex.
