Emerald ash borer quarantine expanded
The Virginia Department of Agriculture and Consumer Services has expanded statewide a quarantine on the emerald ash borer. That was necessary, the agency says, because the borer, which can destroy ash forests, has now been found in the counties of Buchanan, Caroline, Giles, Hanover, Lee, Prince Edward, Stafford and Warren. It previously included Arlington, Charlotte, Clarke, Fairfax, Fauquier, Frederick, Halifax, Loudoun, Lunenburg, Mecklenburg, Pittsylvania and Prince William counties and the cities of Alexandria, Danville, Fairfax, Falls Church, Manassas, Manassas Park and Winchester. Native to Asia, the pest was first discovered in Detroit in 2003, and a year later on nursery stock in Fairfax County. Under this statewide quarantine, the regulated articles, which include ash trees, green (non-heat treated) ash lumber and ash wood products, as well as hardwood firewood, are no longer subject to localized movement restrictions and may now move freely within the state.. Last year, about 5,500 traps used to sample the populations were placed around Virginia. They are baited with natural plant-oil attractant and covered with a nontoxic glue to catch the insects, which are attracted to the color purple. Read my most recent post here.
