Therese Poland, USDA Forest Service.Snapshot : Since the discovery of emerald ash borer in North America in 2002, the USDA Animal Plant Health Inspection Agency and state regulatory agencies have struggled to detect new infestations early and enable a rapid response to mitigate tree damage. Forest Service scientists and a team of other Midwestern researchers compared the efficacy of two of the most promising trap designs and colors and found that purple double-decker traps may improve surveys for early detection of emerald ash borer.

Summary

Early detection of emerald ash borer is notoriously difficult, and an effective artificial trap for the insect is a high priority for national detection surveys and regulatory programs. Numerous studies have evaluated various trap designs, colors, and lures for attraction and detection of emerald ash borer with inconsistent results, possibly due to differing emerald ash borer population densities and tree conditions at the different study sites. Emerald ash borer is attracted to volatiles from ash leaves and from ash bark. Forest Service scientists and partners developed a trap incorporating all of the known visual and olfactory cues attractive to emerald ash borer. They then compared detection rates and numbers of emerald ash borers captured on green or purple double decker traps or prism traps hung in the ash canopy at field sites with different emerald ash borer population densities and found that purple double-decker traps were most effective. These are currently in use..
