  • New York State DEC Tracking New Threat to Beech Trees

    • Jul 15, 2022
    • New York Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) today announced that Beech Leaf Disease (BLD), which affects all species of beech trees, was identified in 35 counties in New York State to date. DEC began tracking BLD in 2018 after it was confirmed in Chautauqua County. Fourteen of the counties with BLD were confirmed in 2022, and more are likely to be identified. At this time there are no specific recommendations for managing trees that are infected with BLD, however, DEC encourages the public to report potential BLD infections using iMapInvasives to help track the disease while research is ongoing. For more information about beech leaf disease, visit DEC's website. For questions about potential tree pests or pathogens, email photos and a description to

  • USDA Statement of Confirmation of Emerald Ash Borer in Oregon

    • Jul 15, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • On July 11, 2022, APHIS confirmed the identification of emerald ash borer in Washington County, Oregon. The Oregon Department of Agriculture believes that the infestation has been in Washington County at least 3-5 years. Regulatory efforts to stop the spread of emerald ash borer were not effective and it has spread through much of the United States. Emerald ash borer is now in 36 States and the District of Columbia.

      APHIS encourages the public to be on the lookout and report emerald ash borer, and has outreach materials including videos, photos, factsheets, and online reporting available. You can also sign up to receive the emerald ash borer program report through our Stakeholder Registry [PDF | 135 KB].

  • ARS Research News - ARS Asian Giant Hornet Specialist Is Part of New Exhibit at the National Museum of Natural History

    • Jul 11, 2022
    • USDA. Agricultural Research Service.

    • Agricultural Research Service research entomologist Matt Buffington is part of a new exhibit "Our Places: Connecting People and Nature" at the Smithsonian National Museum of Natural History (NMNH) in Washington DC. The exhibit explores how peoples' experiences with nature inspire them as well as offering visitors a chance to learn about how dedicated scientists and community members work to protect the environment.

      Among the objects in "Our Places," is part of the actual Asian giant hornet "Nest Zero," the first place these huge hornets set up housekeeping when they arrived in Washington State from Asia in October 2019. Asian giant hornets are a concern because sometimes they can feed on honey bees, buzzsawing through a colony in minutes, and they deliver extremely painful stings to people, but fortunately only if provoked. To quell their spread, Washington State Department of Agriculture, the Agricultural Research Service (ARS) and the Animal and Plant Health Inspection Service (APHIS), both part of the U.S. Department of Agriculture, worked to locate and remove the invasive hornets' nest.

  • South Carolina Officials Announce Infestation of Asian Longhorned Ticks, Ask Public to Help Limit Spread of Tick-Borne Diseases

    • Jul 8, 2022
    • Clemson University.

    • South Carolina public health and livestock officials have recently identified a large population of Asian longhorned ticks infesting a pasture at a cattle farm in York County. This invasive species of tick is not commonly found in the United States, and bites from these ticks have caused illnesses in people, animals and livestock in other countries. As of June 2022, the U.S. Department of Agriculture (USDA) reports Asian longhorned ticks were first identified in the United States in 2010 and have since been found in 17 states. In South Carolina, a small number of these ticks were identified in 2020 on shelter dogs in Lancaster and Pickens counties.

      To help state officials learn more about the prevalence of Asian longhorned ticks in South Carolina, residents are asked to carefully submit ticks suspected to be Asian longhorned ticks for confirmatory identification. This surveillance will help determine tick species presence, distribution, seasonality, and potential tick-borne disease risks.

  • NCDA&CS Finds Spotted Lanternfly in Forsyth County: First Established Presence of the Pest in North Carolina

    • Jun 29, 2022
    • North Carolina Department of Agriculture and Consumer Services.

    • The North Carolina Department of Agriculture and Consumer Services has confirmed the first established presence of the invasive spotted lanternfly (Lycorma delicatula) in the state. Initial surveys indicate the known distribution of the pest is within a 5-mile radius in Forsyth County near Interstate 40 in Kernersville extending to the Guilford County line.

      Early detection and rapid response are critical in the control of spotted lanternfly and the Plant Industry Division has been preparing to provide the most effective response to slow the spread of this invasive pest in the state. If you see or suspect spotted lanternfly in North Carolina submit a picture through the online reporting tool at

  • Invasive Beech Leaf Disease Found in Michigan

    • Jul 5, 2022
    • Michigan Invasive Species.

    • The Michigan departments of Natural Resources and Agriculture and Rural Development recently confirmed the presence of invasive beech leaf disease in a small, private woodlot in southern St. Clair County. Beech leaf disease, not previously known to be in Michigan, is associated with the microscopic worm Litylenchus crenatae, a nematode that enters and spends the winter in leaf buds, causing damage to leaf tissue on American, European and Asian beech species. Trees weakened by leaf damage become susceptible to other diseases and can die within six to 10 years after initial symptoms.

      DNR and MDARD encourage monitoring for any signs of the disease. If you suspect you have found a symptomatic tree, take one or more photos of the infested tree, including close-ups of affected leaves; note the location, date and time; and report it in one of the following ways:

    • Invasive non-native insects have been called the "wildfires of the East," given the damage they cause to trees. One pest, the emerald ash borer, has killed hundreds of millions of rural and urban ash trees. To help arborists and city planners track and treat potential outbreaks, U.S. Forest Service scientists seek efficient monitoring techniques.
