The Buprestidae (Coleoptera) of Minnesota, with a Discussion of the Emerald Ash Borer, Agrilus planipennis Fairmaire

The future impact of the invasive emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), on native North American buprestids is still unknown. To determine how the range and composition of native buprestid species will change over time, knowledge of historical buprestid species distributions is necessary. We utilized a biosurveillance sampling method, namely the use of the native ground-nesting hunting wasp, Cerceris fumipennis Say (Hymenoptera: Crabronidae), along with University of Minnesota Insect Collection (UMSP) records, to create a treatment for the Buprestidae of Minnesota, USA. Additional literature records are included, along with information on host plants, collection method, and collection date range for each species. We examined 5,127 specimens with Minnesota localities, documenting 108 species. Of these, 37 new state records are noted, including 11 collected from C. fumipennis nesting sites between 2013 and 2018. The strengths and limitations of sampling buprestid populations with C. fumipennis biosurveillance are discussed.
