Quarantine Area in Worcester County, Massachusetts Expanded for the Asian Longhorned Beetle

June 22, 2011,  USDA – Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the Asian longhorned beetle (ALB) quarantine area to include an additional four square-miles of Worcester County, Massachusetts.  This action is in response to the discovery of additional trees found to be infested with ALB in the southern section of the city of Worcester, Massachusetts, which is adjacent to the town of Auburn.  The expanded ALB quarantine area in Central Massachusetts now totals 98 square miles. This action is necessary to prevent the human-assisted spread of ALB.
