FOR INFORMATION AND ACTION 
DA-2026-35 
September 1, 2026

Subject: APHIS Expands the Asian Longhorned Beetle (Anoplophora glabripennis)-Quarantine Area in South Carolina 

To: State, Tribal, and Territory Agricultural Regulatory Officials

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), working with Clemson University’s Department of Plant Industry, is expanding areas quarantined for Asian longhorned beetle (Anoplophora glabripennis; ALB) in Charleston County, South Carolina. We are adding 16.5 square miles in Mount Pleasant and 25.2 square miles in Hollywood. APHIS is taking this action because ALB-infested trees were confirmed in Mount Pleasant on August 24, 2025, and additional detections occurred in Hollywood. The attached Federal Order includes the updated quarantine boundaries and references the ALB regulations in 7 Code of Federal Regulations (CFR) 301.51-1 through 301.51-9.

ALB is a destructive wood-boring pest that attacks 12 genera of hardwood trees, including maples. ALB was first detected in the United States in New York in August 1996. ALB was later detected in areas of Illinois (1998), New Jersey (2002, 2004), Massachusetts (2008, 2010), Ohio (2011), and South Carolina (2020). After the completion of control and regulatory activities, and following confirmation surveys, APHIS declared ALB eradicated in Illinois (2008); Hudson County, New Jersey (2008); Islip, New York (2011); Union and Middlesex Counties, New Jersey (2013); Manhattan and Staten Island, New York (2013); Suffolk and Norfolk Counties, Massachusetts (2014); portions of Batavia, Monroe, and Stonelick Townships, Ohio (2018); Brooklyn and Queens, New York (2019); a portion of Tate Township, Ohio (2025); the Town of Holden, Massachusetts (2025) and portions of Nassau and Suffolk Counties, New York (2026). Program activities continue in Worcester County, Massachusetts; Nassau and Suffolk Counties in New York; Clermont County, Ohio; and Charleston and Dorchester Counties in South Carolina.

The APHIS ALB webpage lists all quarantined areas and regulated articles. APHIS will also publish a notice of this change in the Federal Register.
