The use of Cerceris fumipennis ( Hymenoptera: Crabronidae) for surveying and monitoring emerald ash borer ( Coleoptera: Buprestidae) infestations in eastern North America

The beetle-hunting wasp, Cerceris fumipennis Say (Hymenoptera: Crabronidae), native to eastern North America, provisions its subterranean nest almost exclusively with adult metallic wood-boring beetles (Coleoptera: Buprestidae), including the destructive emerald ash borer (Agrilus planipennis Fairmaire, EAB). This wasp provides a unique opportunity to survey indigenous and nonindigenous buprestid diversity. We discuss the accessibility, sustainability, and productivity of C. fumipennis with respect to its application as a buprestid surveying and monitoring tool.
