Pseudacteon tricuspis Borgmeier was released in two Oklahoma counties in 1999 and Pseudacteon curvatus Borgmeier was released in four counties from 2004–2007 as potential biological control agents for the red imported fire ant, Solenopsis invicta Buren. A follow-up survey in 2008 determined that P. curvatus was established in two counties, but P. tricuspis was not. We evaluated a set of six trap/bait combinations in seven southeastern Oklahoma counties that are quarantined for red imported fire ants (one set per county). Traps were in place for 24 hours each week for 11 weeks to determine the presence and seasonal occurrence of Pseudacteon spp. and evaluate efficacy of the trap type for collecting them. Pseudacteon curvatus was collected in five of seven counties, but no P. tricuspis was captured. Fifty-nine flies were captured during the sampling period, and 45% of the flies were captured in McCurtain County. There were no significant differences (P = 0.76) in numbers of flies captured by the Pestick (25 flies) versus the fly-paper (34 flies) traps. There were no significant differences (P = 0.77) in the number of flies captured among the hot dog, peanut butter, and peperoni (25, 17, and 17 flies, respectively). Dispersal of Pseudacteon into other Oklahoma counties needs to be documented as red imported fire ant expands its range. The modified Puckett trap baited with hot dog (cost approximately $0.05 per trap) would provide an affordable, easy way to track such expansion.
