Interpretive Summary: Ambrosia beetles are key pests in ornamental nurseries. In June and July 2011 traps were deployed in Tuskegee National Forest, Macon County, Alabama to test the influence of chemical and visual cues on the capture of ambrosia beetles. The first experiment investigated the attractiveness of traps baited with different mixtures of methanol to ethanol, but no differences in ambrosia beetle captures were detected. The second experiment tested the attractiveness of ethanol-baited traps supplemented with various lights. Ethanol-baited traps supplemented with UV (395 nm) and green (525 nm) lights were more attractive than traps baited only with ethanol, but they were not more attractive than ethanol-baited traps supplemented with blue (470 nm) and red (625 nm) lights. This study indicates ethanol-baited traps supplemented with UV or green LEDs would be useful for detecting various ambrosia beetles.

Technical Abstract: In June and July 2011 traps were deployed in Tuskegee National Forest, Macon County, Alabama to test the influence of chemical and visual cues on for the capture of bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae). \using chemical and visual cues. The first experiment investigated the attractiveness of traps baited with different ratios of methanol to methanol (0:100, 25:75, 50:50, 75:25, 100:0). as an attractive lure. No differences occurred in total scolytine Scolytinae trap captures for any of the varying ratios of ethanol to methanol. The second experiment tested the attractiveness of ethanol-baited traps supplemented with various light emitting diode (LED) wavelengths to Scolytinae. Ethanol-baited traps supplemented with UV (395 nm) and green (525 nm) LEDs were more attractive than traps baited only with ethanol, but they were not more attractive than ethanol-baited traps supplemented with blue (470 nm) and red (625 nm) LEDs. This study suggests indicates ethanol-baited traps supplemented with UV or green LEDs would be useful for detecting various Scolytinae.
