Capture of Nontarget Flies (Diptera: Lauxaniidae, Chloropidae, and Anthomyiidae) on Traps Baited with Volatile Chemicals in Field-Crop Habitats

Figure 5

Mean number of adult Olcella sp. flies per sticky trap (±SE) baited with 100 mg of volatile chemicals in plots near Brookings, SD. Chemicals dispensed on cotton rolls. Bars without the same letters above them indicate that the means differ significantly. (a) Aug 2–4, 2004, corn plot (test #1). (b) Aug 17–19, 2004, soybean (test #2). IMP = 2-isopropyl-3-methoxypyrazine, ETH = ethanol (control), CARY = trans-caryophyllene, PE = 2-phenylethanol, and TERP = terpineol. Zero counts for camphor (CAM) traps not included.
