Abstract Title: USING THE BUPRESTID-SEEKING CERCERIS FUMIPENNIS (HYMENOPTERA: CRABRONIDAE) AS A SURVEY AND PUBLIC OUTREACH TOOL IN ADVANCE (WAKE) OF THE EMERALD ASH BORER ARRIVAL IN THE SOUTHERN U.S.
Abstract Text: The nonnative emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is woodboring beetle which threatens extirpation of susceptible ash trees (Fraxinus spp.) in North America. Cerceris fumipennis Say (Hymenoptera: Crabronidae), a ground-nesting wasp which preys on Buprestidae in eastern North America, is used as a survey tool for the emerald ash borer in the northeastern U.S. and Canada and is known to prey on the emerald ash borer where it occurs. The recent detection of the emerald ash borer in southern states provides an opportunity to complement trapping surveys with the use of C. fumipennis, however knowledge of C. fumipennis in the region is lacking. From 2011–2014 we conducted searches at 155 sites in LA and TX and located C. fumipennis aggregations at 25% (n=39) of these sites. We collected 1559 buprestids representing 35 species (some of which were state records) from two aggregations in Louisiana between May and August in multiple years. Buprestid collections at these aggregations and observations of C. fumipennis activity at a third aggregation indicated the number of buprestid species and individuals collected declined significantly from May to July, and collections tended to be greater in the afternoon hours. Our results suggest that C. fumipennis is a feasible sampling tool and a useful addition to ongoing emerald ash borer surveys in the south.
