Purple Sleds in the Trees?
Written by Dr. Jim Finley, Phone: 814-863-0402, firstname.lastname@example.org
Last year driving through western Pennsylvania, there were lots of purple sleds hanging in trees along the highways. They weren't actually purple sleds but caught out of the corner of the eye, they were peculiar. Actually, they are traps to monitor the spread of the Emerald Ash Borer (EAB) beyond the currently quarantined Pennsylvania counties of Allegheny, Armstrong, Beaver, Bedford, Butler, Indiana, Juniata, Lawrence, Mercer, Mifflin, Washington, and Westmoreland Counties.
If you have seen these rectangles (actually they are three-sided structures) of purple suspended in trees you might have wondered. According to the DCNR EAB website (http://www.dcnr.state.pa.us/forestry/fpm_invasives_EAB.aspx), these purple panel traps baited with a Manuka oil lure in the center are a major detection tool for EAB monitoring. The outside of each panel has a coating of Pestick glue to catch adults attracted to the trap. Traps are monitored throughout the summer with the lure replaced once in late July.
The PA Department of Agriculture is conducting a delimiting survey for EAB this summer in twenty-seven counties surrounding the western quarantined counties, the central quarantined counties, and across the northern tier, including Erie, Crawford, Warren, Venango, Forest, Clarion, Jefferson, Cambria, Somerset, Fayette, Greene, Fulton, Huntingdon, Blair, Centre, Clearfield, Perry, Snyder, Union, Clinton, Cameron, Elk, McKean, Potter, Tioga, Bradford, and Susquehanna Counties. Additionally you may see traps in other eastern counties.
Nearly 4 percent of all the trees in Pennsylvania are ash (about 300 million trees according to the USDA Forest Service). We prize ash for the products it provides -- who doesn't enjoy the sound of a well swung baseball bat or the shade of a spreading ash in the yard or along a city street.
Consider these rectangles of purple in trees as a visual reminder of your role in protecting the state's valuable ash resource. As you prepare for summer trips, vacations, and picnics, recall the admonition -- DON'T MOVE FIREWOOD. Research has shown that people moving firewood is a major avenue of spread for EAB. Don't take your firewood with you. Gather or purchase it at your destination.
