Buprestidae collected as prey by the solitary, ground-nesting philanthine wasp cerceris fumipennis (Hymenoptera: Crabronidae) in North Carolina

Abstract

The solitary, ground-nesting crabronid wasp Cerceris fumipennis Say excels at detecting buprestid diversity in a given geographic area, and after the introduction of the invasive pest emerald ash borer (Agrilus planipennis Fairmaire) to the United States in 2002, has been developed as an effective tool for the biosurveillance of pest Buprestidae in eastern North America. Here we report records of Buprestidae collected from foraging C. fumipennis in 13 North Carolina counties over the course of three seasons (2009-2011). Nests of the wasp were located, and beetle prey collected from foraging females in three geographic regions, with a concentration on the western, mountainous area of the state. In total, 909 beetles were collected, comprising 52 buprestid species that included eight native pests and 17 species of Agrilus. Our results emphasize the utility of C. fumipennis in documenting buprestid biodiversity and in detecting forest pests. Eight new state records and five new prey records for the wasp are here recorded. © 2013 Entomological Society of America. © 2013 Entomological Society of America.
