Emerald ash borer, laurel wilt disease, thousand cankers disease, and the European gypsy moth are likely to be brought into North Carolina in or on firewood. The use of local firewood is an important factor in preventing the spread of potentially devastating invasive species to our state's forests. Please keep this in mind as you prepare for your outdoor recreation activities. See Forest Health Invasive Pest Maps for more information about pest monitoring.

The newly launched Vermont Forest Invasive Pest Status Map offers an interactive platform to track the spread of invasive species such as beech leaf disease, elm zigzag sawfly, elongate hemlock scale, emerald ash borer, and hemlock woolly adelgid across the state. The application provides users with a comprehensive overview of town infestations and detection years for each invasive pest.

As part of the ongoing response to the recent discovery of the Emerald Ash Borer (EAB) within the state, Vermont has joined the United States Department of Agriculture (USDA)'s 31-state quarantine boundary. The quarantine will help reduce the movement of infested ash wood to un-infested regions outside of Vermont's borders. Ash wood may not be moved from Vermont to Maine, Rhode Island, or 7 counties in New Hampshire because the pest has not been identified in these states and counties. Vermont is also developing a series of slow-the-spread recommendations, initially including recommendations for handling logs, firewood, and other ash materials. To learn more about these recommendations, to see a map indicating where EAB is known to occur in Vermont, and to report suspected invasive species like EAB, visit vtinvasives.org

About 82% of the U.S. population lives in urban areas, and that number is growing. “Frequent travel to and from cities means that trees in urban areas have high rates of exposure to invasive species like the emerald ash borer,” says Frank Koch, a USDA Forest Service research ecologist and co-author of a study in the Journal of Applied Ecology about the impacts of invasive insects on urban trees.

New research from the University of Minnesota’s Minnesota Invasive Terrestrial Plants and Pests Center (MITPPC) shows a possible path forward in controlling the invasive pest, the emerald ash borer (EAB), that threatens Minnesota’s nearly one billion ash trees.

In a recent study published in Fungal Biology, MITPPC researchers identified various fungi living in EAB-infested trees — a critical first step in finding fungi that may be harnessed to control the spread of EAB, and ultimately, prevent ash tree death. 

Emerald ash borer (Agrilus planipennis) is an exotic, invasive, wood-boring insect that infests and kills native North American ash trees, both in forests and landscape plantings. With EAB now in several areas of the Show-Me State - and its ability to hitchhike on firewood - the probability of it spreading to noninfected areas in the state is high.

How can an insect that is smaller than a penny cause so much ecological, economic, and cultural devastation? The emerald ash borer, an invasive beetle native to Asia, is one of the most destructive invasive species in North America. These tiny pests killed tens of millions of ash trees in the northeast – and continue to this day.

In Maine, a coalition of Indigenous and non-Indigenous researchers, tribal members, state and federal foresters, conservation groups, and local communities have been working for the past twenty years to prepare for the onset of emerald ash borer in northeastern forests. The group, called the Ash Protection Collaboration Across Wabanakik, is focused on identifying research-informed strategies to protect the future of ash trees.

Electronic noses are sensitive to a vast suite of volatile organic compounds that every living organism emits. A new USDA Forest Service study shows that e-noses can detect emerald ash borer (Agrilus planipennis) larvae lurking under the bark – an early, noninvasive detection method. 

Ash and elm trees play important roles in the U.S. economy, culture, and environment. In the eastern United States, elm (especially American elm) and ash trees are in trouble because of two threats: the emerald ash borer (an insect that attacks ash) and Dutch elm disease (caused by a fungus that sickens elms). These pests are causing ash and elm trees to die off quickly. Because elm and ash trees serve important ecological roles where they are found, the loss of these trees can lead to profound changes across urban and rural environments.

Washington state agencies are asking for your help to check your trees for signs and symptoms of invasive insects. Damaging invasive insect species, such as spotted lanternfly, longhorned beetles, and emerald ash borer, are emerging in their adult form. ate summer is often the peak time for these invasive insects to emerge from trees in their adult stage. If you see or suspect you see an invasive insect, report a sighting.

ITP is pleased to announce the release of seven new screening aids for important Coleoptera and Lepidoptera pests. These were designed specifically to be used when examining traps or through visual inspection as part of surveys conducted by state cooperators for the APHIS PPQ Cooperative Agricultural Pest Survey (CAPS) program. CAPS surveys help officials monitor and gather data about pests on high-risk hosts and commodities, including pests that may have been recently introduced to the United States. The new screening aids are for city longhorn beetle, Agrilus of concern, pinecone and bamboo longhorn beetles, tomato fruit borers, coconut rhinoceros beetles, spruce longhorn beetles, and velvet longhorn beetle. All of ITP's CAPS screening aids can be found on the ITP website and on the CAPS Resource and Collaboration site Screening Aids page.
