Biology and management of Systena frontalis (Coleoptera: Chrysomelidae) in ornamental plant nurseries

Abstract

Systena frontalis (F.) (Coleoptera: Chrysomelidae) is a serious insect pest species of container ornamental plant nurseries, widespread in the central and eastern United States. Adults feeding causes shotholes and skeletonization to the foliage of affected plants, which can reduce aesthetic value, and marketability of the ornamental plants. This paper reviews the biology and current management approaches used against S. frontalis in ornamental plant nurseries in the United States. Information gathered from the cranberry (Vaccinium macrocarpon Ait.) production system is included where they are appropriate and supplementary to the discussion. The paper also discusses the research, extension, and economic questions prioritized by the stakeholders dealing with S. frontalis problems in the container nurseries.
