BACKGROUND: Maples ( Acer spp.) in production nurseries are vulnerable to numerous arthropod pests that can stunt or even kill the young trees. Seventeen cultivars representing various Acer species and hybrids were evaluated for extent of infestation or injury by shoot and trunk borers ( Proteoteras aesculana, Chrysobothris femorata ), potato leafhopper ( Empoasca fabae ), Japanese beetle ( Popillia japonica ), maple spider mite ( Oligonychus aceris ) and calico scale ( Eulecanium cerasorum ). Evaluations were done in replicated field plots in central and western Kentucky. RESULTS: All of the maples were susceptible, to varying degrees, to one or more key pest(s). Red maples ( A. rubrum ) were relatively vulnerable to potato leafhopper injury and borers but nearly free of Japanese beetle feeding and spider mites. Sugar maples sustained conspicuous Japanese beetle damage but had very low mite populations, whereas the opposite was true for Freeman maples ( A . × freemanii ). A. campestre was heavily infested by calico scale. Within each species or hybrid there were cultivar differences in degree of infestation or damage by particular pests. CONCLUSION: The results should help growers to focus pest management efforts on those plantings at greatest risk from particular pests, and to choose cultivars requiring fewer insecticide inputs to produce a quality tree.
