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

Figure 6

Mean number (±SE) of male Delia flies captured near Brookings, SD, on sticky traps baited with a volatile attractant. (a) Spring wheat, Jun 15–17, 2005 (test #3). (b) soybean, Jul 14–16, 2005 (test #6). PE = 2-phenylethanol, MS = methyl salicylate, and ETH = ethanol (control), each at 100 mg on a cotton roll; PECL = 2-phenylethanol and MSCL = methyl salicylate, each at 2 mg on a controlled-release lure. For each graph, bars without the same letter above them indicate significant differences between means.
