There is no long-range sex pheromone identified for this family that could be exploited for sampling. In addition, currently available traps are only intermittently successful at detecting species of interest, including the invasive emerald ash borer, Agrilus planipennis Fairmaire, when at low densities. One method used to sample emerald ash borer and other buprestids is biosurveillance with a native ground-nesting hunting wasp, Cerceris fumipennis Say (Hymenoptera: Crabronidae). Cerceris fumipennis hunts for a wide range of buprestids, does not sting humans, and tends to nest at easily accessible human-disturbed sites such as baseball diamonds, making it easy for non-specialists to monitor nests and collect beetles in their communities. This work utilizes C. fumipennis-collected beetles along with existing museum records to create a checklist of buprestid species in Minnesota, investigates site-level variables that may influence the number and diversity of beetles collected by C. fumipennis, and elucidates individual outcomes for citizen science volunteers who monitor nesting aggregations of C. fumipennis.enbiodiversitybiosurveillanceCerceris fumipenniscitizen scienceemerald ash borerforest pestsThesis or Dissertation
