Technical Abstract: Exotic scarabs (Coleoptera: Scarabaeidae) such as Anomala orientalis and Rhizotrogus majalis are serious pests of ornamental nursery crops in northern Ohio. The larval stage of these insects feed on the roots of ornamental trees often stunting or killing their hosts. The biology, life history, and management of these insects and other exotic scarabs was studied in commercial nurseries in northern Ohio. Information on life history and it’s relationship to plant phenology; management techniques such as chemigation and subsurface application of chemical and biological controls; and parasitism by natural enemies will be presented. This information enables growers to better manage these pests by providing effective treatment methods, more accurate timing of treatments, effective use of biological controls, and conservation of natural enemies.
