Alaska Submit-A-Tick Program

Alaska Department of Environmental Conservation. Division of Environmental Health. State Veterinarian.

In 2019, the Alaska Office of the State Veterinarian, in collaboration with the Alaska Department of Fish and Game and the University of Alaska, began the Alaska Submit-A-Tick Program. Through this program, individuals who find ticks on themselves, their family members, pets, or wildlife (e.g. hunted or trapped animals) can submit ticks for species identification and pathogen testing. Researchers are asking Alaskans to submit ticks to help determine which tick species are currently in the state. Tick submissions will also help us learn more about how ticks are being imported into Alaska so that we can create effective strategies to limit their introduction. Ticks can transmit bacteria, parasites, and viruses that can cause diseases in humans and wildlife. Pathogen testing allows us to assess tickborne disease risk in the state.

Ash Tree-Killing Insect Confirmed in Delaware (Aug 23, 2016)
Delaware Department of Agriculture.
A destructive, invasive beetle that kills ash trees, the emerald ash borer (EAB), has been confirmed in Delaware, making it the 28th state to have found the insect, the Delaware Department of Agriculture announced today. Delaware will be added to a federal quarantine already in 27 other states restricting the interstate shipment of all ash wood and wood products - ash nursery stock, green lumber, waste, compost and chips - as well as hardwood firewood of all species.
Boxwood Blight
New Hampshire Department of Agriculture, Markets, and Food.
Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.
Bureau of Environment - Invasive Species Best Management Practices

New Hampshire Department of Transportation.

To address mounting concerns over invasive plants and the role NHDOT activities play in the spread of these plants along roadsides, Best Management Practices (BMPs) have been developed with input from Maintenance Districts, the Roadside Development Section, the Bureau of Construction, and the NH Department of Agriculture. Implementation of these BMPs will help prevent the spread of invasive plants caused by maintenance and construction activities.

Delaware Expands Spotted Lanternfly Quarantine in New Castle County (Sep 18, 2019)

Delaware Department of Agriculture.

The Delaware Department of Agriculture (DDA) announced today that they expanded the spotted lanternfly quarantine to include all portions of New Castle County north of the Chesapeake and Delaware Canal. This is due to recent detections of established populations outside of the initial quarantine zone enacted in February 2019 that included eleven zip codes. "This expansion is necessary in our attempt to eradicate, control, and prevent the spread of spotted lanternfly in Delaware and to surrounding states," said Secretary of Agriculture Michael T. Scuse. The spotted lanternfly is a destructive invasive plant hopper that attacks many hosts including trees, shrubs, orchards, grapes, and hops. For more detailed information regarding the quarantine, permitting, treatment, or to report a sighting of spotted lanternfly, visit the Delaware Department of Agriculture’s dedicated spotted lanternfly webpage or call the dedicated spotted lanternfly hotline at (302) 698-4632.

Emerald Ash Borer
Illinois Department of Agriculture. Bureau of Environmental Programs. Division of Natural Resources.
Native to Asia, the Emerald Ash Borer is an exotic beetle that was unknown in North America until June 2002 when it was discovered as the cause for the decline of many ash trees in southeast Michigan and neighboring Windsor, Ontario, Canada. It has since been found in several states from the east coast spanning across the midwest and in June 2006, we discovered that it had taken up residence in Illinois.
Emerald Ash Borer Found at New Delaware Sites (Nov 19, 2018)
Delaware Department of Agriculture.
Emerald ash borer (EAB), a destructive insect from Asia that attacks and kills ash trees, has been confirmed at two new sites in Delaware: one near Middletown, New Castle County, and another near Seaford, Sussex County. Originally found in northern Delaware in 2016, the new detections create added urgency for homeowners and municipalities to determine if they have ash trees on their property and decide on possible management options. Current guidelines recommend the removal or treatment of ash trees if located within 15 miles of a known infestation. Because Delaware is geographically small and EAB can go undetected for years, residents are urged to educate themselves now and take action.
