Pest Alert: Sirex woodwasp (Sirex noctilio) found in Pennsylvania and expands range in New York (August 2006)

On July 24, 2006 a female Sirex woodwasp was collected from a trap in Tioga County Pennsylvania. This wasp was identified by Cornell University and the Systematic Entomology Lab in Beltsville, MD confirmed the identity of the insect. The first detection of the Sirex woodwasp in the United State was in 2004 is Oswego County, New York. In 2005 the wasp was detected in 4 more NY counties (Cayuga, Onondaga, Seneca, and Wayne). As a result of the 2006 survey conducted by state and federal officials, the Sirex woodwasp has been detected in an additional 15 counties (Allegany, Chautauqua, Erie, Genesee, Jefferson, Livingston, Madison, Monroe, Niagara, Oneida, Ontario, Orleans, Schuyler, Wyoming, and Yates). For those unfamiliar with the geography of NY visit the NY Department of Environmental Conservation Sirex webpage for a map showing the positive counties: http://www.dec.ny.gov/animals/7248.html. The woodwasp has also been reported from Durham, Leeds and Greenville, Prince Edward, and Waterloo Counties in Ontario, Canada.

In Massachusetts, the MA Dept. of Agricultural Resources and MA Dept. of Conservation and Recreation are cooperating with the USDA, APHIS and U.S. Forest Service in conducting Sirex noctilio surveys. To date we have found no S. noctilio specimens in traps in Massachusetts. In the New England state and federal agencies are conducting Sirex surveys in Connecticut, Maine, New Hampshire, Rhode Island, and Vermont.
