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

Figure 3

Mean number of lauxaniid flies per sticky trap (±SE) baited with volatile chemicals from Jul 13 to Jul 15, 2005, in a corn plot near Brookings, SD (test #4). For each species, bars without the same letters above them indicate that the means differ significantly. PE = 2-phenylethanol, MS = methyl salicylate, IMP = 2-isopropyl-3-methoxypyrazine, and ETH = ethanol (control), each at 100 mg on a cotton roll. (a) Adult Homoneura bispina; (b) adult Camptoprosopella borealis.
