Currently, three other species (P. tricuspis Borgmeier, P. litoralis Borgmeier, and P. obtusus Borgmeier) have been released and are established in the United States (Vogt and Streett 2003, Porter and Gilbert 2004), and their effects are under study. Foraging rate was significantly higher by M workers than by P workers in the absence of parasitoids (308.50 ± 42.33 versus 221.33 ± 38.34 ants for M and P nests, respectively; t = 3.74, df = 10, P = 0.0039; two-tailed t-test).

D.A. While internal development of the fly larvae eventually decapitates and kills individual ants (Porter et al. Sampling locations in Phillips Co. were located on the western levee of the Mississippi River, northwest of Friars Point, MS (Fig. is achieved with a variety of methods: actively through direct collections of flies at disturbed ant colonies with either manual or electrical stimulation (Barr & Calixto 2005; Morrison & Porter 2005), or passively by trapping with a sticky trap (Puckett et al. In the laboratory, P. curvatus mainly parasitized small workers, which are smaller than the mean size of the colonies of both social forms (Fig. Nests with more than one queen were considered polygyne (P). Subcastes were catalogued as major (ants retained in the sieve mesh #20, with a pore size of 1,190 μm); big (ants retained in the sieve mesh #18, with a pore size of 1,000 μm); medium (ants retained in the sieve mesh #20, with a pore size of 840 μm); small (ants retained in the sieve mesh #25, with a pore size of 710 μm), and minor (ants that passed through the sieve mesh #25 with a pore size of 710 μm).

We do not know if different biotypes are true sibling or cryptic species. M.R. Our field site was composed of three grassland patches separated by 20-40 m between each other. 2004). Brown To determine Pseudacteon establishment and expansion, sticky traps were used to monitor phorid fly species at and near 10 release sites, in counties bordering neighboring states, and along regional transects. 3K), 20 km northwest, may suggest their origin, although P. curvatus appeared in no samples taken from the Pike County release site transect. Measures of oviposition preference included the number of attacks ("ovipositions") counted during the first 15 min after release and the orientation time (time invested in detecting before beginning oviposition). present on the remaining 55 traps in this region. 2004, Estrada et al. means you agree to our use of cookies. 2007). 1). Patrock Passive Pseudacteon trapping with the modified Puckett trap provided advantages over direct collection from disturbed mounds.
