  • Testing Blight Resistance in American Chestnuts

    The American chestnut (Castanea dentata) was a keystone tree species in the eastern U.S., once found in the forest overstory from Maine to Georgia. The loss of the "mighty giant" to chestnut blight (Cryphonectria parasitica), a fungal disease accidentally imported from Asia in the early 1900s, reduced the once dominant chestnuts to remnant understory sprouts. After eight years of field testing, USDA Forest Service research forester Stacy Clark and her colleagues evaluated blight resistance and survival of the backcross-generation American chestnut seedlings, known as BC3F3. Their results were published in Forest Ecology and Management.

    The fungus behind white-nose syndrome, a disease that has devastated bat populations in North America, may have an Achilles' heel: UV light, according to a study conducted by the Forest Service and its partners.

    "White-nose syndrome is the single biggest threat to many North American bat species and one of the most pressing conservation challenges facing America’s wildlife today. Investing in defeating WNS must be a priority, and the results from this study and contributing research give us hope that we can develop the tools to more effectively manage the fungus that causes the disease."

    New techniques use radiation to eliminate dangerous mosquitoes. The Aedes aegypti mosquito is notorious for spreading dengue virus, yellow fever virus, chikungunya virus, and Zika virus, among other ailments. While many mosquitoes do not feed on people, or even domestic animals, this mosquito targets humans causing disease to millions of people throughout the world. ARS researchers with scientists from the University of Florida have developed a new technique for using radiation to control mosquito populations.

  • Thousand Cankers Disease

    Pennsylvania Department of Agriculture.

    On Aug. 9, 2011, the department in cooperation with the U.S. Department of Agriculture and Penn State Cooperative Extension confirmed the presence of Thousand Cankers Disease in black walnut trees in Bucks County. Since this pest complex cannot be eradicated in Pennsylvania, and since black walnut is of high value to the forest products industry and to forest and urban ecologies, the Pennsylvania Department of Agriculture is joining with state and federal agencies and Penn State Cooperative Extension to slow the spread of TCD in the state through monitoring and quarantine. For more information or to report a possible case of Thousand Cankers Disease on walnut please contact your Pennsylvania local county cooperative extension office or contact the Invasive Species Hotline at 1-866-253-7189 or Badbug@pa.gov.
