UPDATE: APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

FROM APHIS EMAIL:

Subject:           APHIS Establishes Box Tree Moth (Cydalima perspectalis) Quarantines in Delaware and Pennsylvania

To:                   State, Tribal, and Territory Agricultural Regulatory Officials

Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the Delaware Department of Agriculture and the Pennsylvania Department of Agriculture (PDA), is adding the entire State of Delaware and Erie County, Pennsylvania to the box tree moth (BTM; Cydalima perspectalis) quarantined area.

APHIS is taking this action in response to the confirmed detections of BTM in a residence in Little Creek, Delaware, on July 11 and in Lakeside Cemetery in Erie, Erie County, Pennsylvania, on August 29. PDA has established an intrastate quarantine area for BTM that parallels the Federal quarantine. This Federal Order supersedes Federal Order DA-2024-17.

To prevent the spread of BTM, APHIS considers it necessary to regulate the interstate movement of regulated articles of boxwood from quarantined areas. Boxwood plants may only be moved interstate from a quarantined area from an establishment operating under a compliance agreement, and only if accompanied by a certificate issued by a state agricultural authority certifying that the requirements of this Federal Order and the compliance agreement have been met. These requirements will prevent producers and distributors of boxwood from moving infested plants interstate. State agricultural authorities may prescribe additional safeguards and protocols.

APHIS prohibits movement of all other regulated articles of boxwood, including plant parts, pieces, cuttings, clippings, debris, and any portion of the plant, alive or dead, except for decorative purposes.

The attached Federal Order (click here) and additional information about BTM are located on the APHIS box tree moth webpage. For additional information, you may contact:

National Policy Manager
