APHIS-2025-0011 APHIS Field Release of the Knotweed Psyllid Aphalara itadori (Hemiptera: Psyllidae) for Classical Biological Control of Japanese, Giant, and Bohemian Knotweeds, Fallopia japonica, F. sachalinensis, and F. x bohemica (Polygonaceae), in Alaska Nonrulemaking 2025-07-08T13:50:36Z 0b000064b8ce7ab2   The U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ), Pests, Pathogens, and Biocontrol Permits (PPBP) is proposing to issue permits for release of the knotweed psyllid, Aphalara itadori (Hemiptera: Psyllidae) into Alaska. Aphalara itadori would be used for the classical biological control of Japanese, giant, and Bohemian knotweeds (Fallopia japonica, F. sachalinensis, and F. x bohemica (Polygonaceae)) in Alaska. The permit applicant’s purpose for releasing A. itadori is to reduce the severity of infestations of invasive knotweeds in Alaska. Invasive knotweeds in North America are a complex of three closely related species in the family Polygonaceae that were introduced from Japan during the late 19th century. They include Fallopia sachalinensis (giant knotweed), F. japonica (Japanese knotweed), and the hybrid between the two F. x bohemica (Bohemian or hybrid knotweed). The exact date of knotweed introduction into Alaska is unknown but thought to be in the early 1980’s. Since that time, knotweeds have spread throughout the panhandle of southeast Alaska and there are additional introductions in southcentral Alaska and on Kodiak Island. Existing options for management of invasive knotweeds are expensive, temporary, ineffective, and can have nontarget impacts. Current control of knotweeds in Alaska involves application of herbicides, often extended over many years because of persistent root regrowth. Known eradication at a site has not been achieved as new shoots arise, sometimes years after treatment. The persistent nature of knotweed creates a number of issues for herbicide control, including significant long term effort needed for control, difficult access of remote infestations, and treating infestations under different land managers and private lands that may not approve of herbicide use. Biological control has the potential to provide widespread and sustained reduction in knotweed abundance at a very low cost. For these reasons, the applicant has a need to release A. itadori, a host-specific, biological control organism for the control of invasive knotweeds, into the environment of Alaska.
