Cities contain dozens of street tree species, each with multiple arthropod pests. A survey was used to identify the most common and damaging pests of the most common trees in the southeastern U.S.A. Tree genera varied in number of common pests from Zelkova, which has few pests, to Quercus, which has many pests from many feeding guilds. Sucking pests, such as aphids and scale insects, were rated among the most important pests on several tree genera, including Acer, Liriodendron, and Lagerstroemia. Defoliators, primarily caterpillars, were ranked highest on Quercus spp. Knowledge of the most common and damaging pests will help focus integrated pest management development and educational activities.
