The Pennsylvania Fish and Boat Commission (PFBC) has issued a strong advisory to encourage anglers who catch invasive Northern Snakeheads in the lower Susquehanna River, and elsewhere in the Commonwealth, to report and dispose of any fish caught. This advisory follows multiple Northern Snakehead captures in Conowingo Reservoir by anglers and natural resource agency biologists this summer, including the first evidence of Northern Snakehead reproduction in the reservoir.

It is now illegal to sell, grow, or plant Callery pear (also known as Bradford pear) in Ohio because of its invasive qualities and likelihood to cause economic or environmental harm. There is no requirement for the removal of existing plants, but the Ohio Department of Natural Resources (ODNR) Division of Forestry encourages control and removal to benefit native forest ecosystems.

The Minnesota DNR’s Invasive Species Program has embarked on an exciting project that aims to better promote the adoption of desirable aquatic invasive species (AIS) prevention behaviors and create positive social norms supporting AIS prevention in Minnesota.

The Asian Longhorned tick (ALT), which was first discovered in the United States in 2017 has now be found in 19 states including Virginia. Currently, there are 38 Virginia counties with established ALT populations. As ALT populations have increased, a concern for the health of livestock in affected areas has increased as well. ALT is a vector for the parasite Theileria orientalis Ikeda which can cause theileriosis in livestock, including cattle.

The Texas Parks and Wildlife Department (TPWD) reports that invasive quagga mussels have been detected for the first time in Texas. The quagga mussel discovery was made by National Park Service (NPS) staff at the International Amistad Reservoir in the Rio Grande basin along the Texas-Mexico border near Del Rio. Quagga mussels are a close relative of the zebra mussel, which has invaded 33 Texas lakes across six river basins since it was first introduced in Texas in Lake Texoma in 2009. In addition to being the first detection of quagga mussels in Texas waters, this is also the first finding of any invasive mussel species in the Rio Grande basin.

TPWD and partners monitor for invasive mussels in Texas lakes, but anyone who finds them in lakes where they haven’t been found before should report them immediately by emailing photos and location information to AquaticInvasives@tpwd.texas.gov.

Widespread sampling for invasive crayfish had never occurred in Kansas lakes – that is, until the Kansas Department of Wildlife and Parks (KDWP) recently funded a university project focused on the freshwater crustacean. KDWP's Aquatic Nuisance Species Program and Ecological Services section funded the project with the overarching goal of establishing sampling protocols that could then be used for long-term monitoring of both native and invasive crayfish in Kansas. During capturing efforts at McPherson State Fishing Lake – one of several small waterbodies slated to be inspected in the state – university researchers collected multiple Rusty Crayfish. Rusty Crayfish have not previously been documented in the wild in Kansas, making this official "discovery" the first of its kind.

Anglers, boaters and watersport enthusiasts are encouraged to keep their eyes open for this invasive species, which can be identified by its trademark large, black-tipped claws and rust-colored spots on its upper shell. If one is discovered, freeze it in a sealed plastic bag, note the date and location of capture, and contact KDWP's Emporia Research and Survey Office at (620) 342-0658.

The Lionfish Challenge 2022, the seventh annual, is a summer-long tournament that rewards divers for their lionfish harvests. The tournament boasted a total of 707 registered participants, the most in the program’s history. 196 divers conducted a total of 676 trips throughout the state during the 3-month tournament and brought in a whopping 25,299 lionfish.

Trying to reduce the spread of invasive species in Rhode Island waters, the Department of Environmental Management (DEM) has amended the state's Freshwater Fisheries Regulations to prohibit the transport of any plant or plant part into or out of any Rhode Island waterbody on any type of boat, motor, trailer, fishing supplies, or gear. The new regulation carries a $100 fine for each violation. "Many of the aquatic invasive plants in Rhode Island can reproduce from just one small plant fragment and do not need entire root systems to successfully establish in a new spot," said Katie DeGoosh-DiMarzio, Environmental Analyst with DEM's Office of Water Resources. "Cleaning off every bit of plant from recreational gear used at one pond is essential before visiting another — this includes boats, kayaks, canoes, motors, trailers, paddles, jet skis, fishing gear, waders, water tubes, and anchors. These efforts help combat the spread of aquatic invasive species in Rhode Island waterbodies."

The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

The Port of San Diego, along with the Southern California Caulerpa Action Team (SCCAT), the City of Coronado, and the Coronado Cays Homeowners Association (CCHOA), are responding to the discovery of an invasive seaweed scientifically known as Caulerpa prolifera in the Coronado Cays area of San Diego Bay.

In late September, divers found a small patch of Caulerpa prolifera while conducting an in-water pre-construction eelgrass/Caulerpa dive survey as a permit condition for a dock replacement project. Additional patches were discovered nearby during follow-up surveys. The total find within the Cays is about one-quarter of an acre. The SCCAT has prepared a Rapid Response Eradication Plan to address the immediate need to eradicate this invasive species.

Spotted lanternfly is a threat to Maryland and the U.S. The Maryland Department of Agriculture issued a quarantine October 28, 2019 in an effort to contain the invasive species in Cecil and Harford counties after the spotted lanternfly was spotted in Cecil’s northeastern corner and along Harford’s northern border. See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.
 

The South Dakota Game, Fish and Parks (GFP) is seeking comments on the draft "Aquatic Invasive Species (AIS) Strategic Plan." All individuals interested in AIS management in South Dakota have from now through December 31, 2022, to provide suggestions and comments on the revised plan in its current form. The draft AIS strategic plan can be found online at: https://gfp.sd.gov/management-plans/.

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) caught 202,300 spongy moths (formerly named gypsy moth) in 10,044 traps this summer as part of the federal Slow the Spread of the Spongy Moth Program. "Wisconsin weather trends have allowed the spongy moth population to grow over the last several years," said Michael Falk, DATCP's trapping coordinator.

Spongy moth is an invasive pest that has been spreading westward since its introduction to North America. Caterpillars feed on the leaves of many species of trees and shrubs, especially oaks, and can cause severe leaf loss when feeding in large numbers. For more information, call (800) 642-MOTH (6684), email spongymoth@wisconsin.gov, or visit www.spongymoth.wi.gov.

The Rhode Island Department of Environmental Management (DEM) announces that the spotted lanternfly (SLF), an exotic pest that targets various plants and trees, has been detected for the first time in Rhode Island. Native to Asia, SLF is most commonly associated with "Tree of Heaven" (Ailanthus altissima) plants and also feeds on a wide variety of agricultural crops such as grape, apple and hops; and several native species of plants and trees including maple, walnut and willow.

A single SLF was found in an industrial/commercial area in Warwick near Jefferson Blvd, and a photo of the insect was sent to DEM through its online agricultural pest alert system. DEM's Division of Agriculture confirmed the sighting on August 2 and is asking the public to report any suspected sightings at the Spotted Lanternfly Sighting Report Form. No known population of SLF is currently present in this area. DEM will be conducting an extensive survey of the area based on US Department of Agriculture (USDA) recommendations to determine if there is any further presence of the invasive insect and will be providing outreach materials to businesses in the area.

Spotted lanternfly (Lycorma delicatula) was found in Indiana for the first time in Switzerland County earlier this week, the farthest west the insect has been found. A homeowner in Vevay contacted DNR’s Division of Entomology & Plant Pathology (DEPP) with a picture that was taken outside his home of a fourth instar, or developmental stage, larvae. DEPP staff surveyed the site and discovered an infestation in the woodlot adjacent to a few homes in the area. DEPP and USDA are conducting an investigation to determine exactly how large the infestation is and where it could have come from, as well as how to limit the spread and eradicate the population.

The Indiana DNR is asking for all citizens to keep an eye out for spotted lanternfly. The bright color of both the last instars and the adults of the insect should be present at this time of the year. Anyone that spots signs of the spotted lanternfly should contact DEPP by calling 866-NO EXOTIC (866-663-9684) or send an email to DEPP@dnr.IN.gov.

A population of the invasive Spotted Lanternfly (SLF) has been found in Mingo Junction, Ohio just south of Steubenville, along the Ohio River. The initial report came from a resident who spotted a dead adult SLF on a commercial building on October 19, 2020. When Ohio Department of Agriculture (ODA) Plant Pest Control inspectors arrived, they were able to capture five live adult SLF in trees located nearby. ODA has been working with the United States Department of Agriculture, Ohio Department of Natural Resources, Ohio State University Extension, and the Ohio Grape Industries Committee to do visual surveys, insect trapping, and outreach in the region.

The public is the first line of defense against the SLF. If you believe you have seen an SLF in your area, you can easily report a suspected infestation by going to ODA’s Spotted Lanternfly Information Page and filling out a suspected infestation report. You may also call the Plant Pest Control Division at 614-728-6400.

Today, Michigan Department of Agriculture and Rural Development (MDARD) Director Gary McDowell confirmed the state’s first detection of spotted lanternfly (Lycorma delicatula) in Michigan. A small population of spotted lanternfly was detected in Pontiac in Oakland County last week with the United States Department of Agriculture (USDA) confirming the finding on August 10.

Spotted lanternfly moves easily on firewood, tires, campers, vehicles and more. Prevention and early detection are vital to limiting the spread of spotted lanternfly. If you find a spotted lanternfly egg mass, nymph or adult, take one or more photos, make note of the date, time and location of the sighting, and report it online to Eyes in the Field. Photos are necessary to verify a report and to aid in identification.

The Illinois Department of Agriculture has confirmed the first detection of spotted lanternfly (Lycorma deliculata) in Illinois. Following a report of a live adult on Sept. 16, state, federal, and local officials coordinated a site visit near the area of the report and identified a moderately populated area of spotted lanternfly (SLF) on Sept. 18. Specimens were collected and submitted for identification, and confirmatory results were received on September 26. The spotted lanternfly does not present any human or animal health concerns.

If you see SLF or suspect it, report it to lanternfly@illinois.edu. A fact sheet, including photos, is available through the University of Illinois Extension [PDF, 1.6 MB].

Have you recently planted maple, crabapple, or other trees? MDAR is asking everyone to check them for spotted lanternfly egg masses or recently hatched nymphs after we were alerted that trees or shrubs with SLF egg masses may have been recently shipped to Massachusetts. Please give all nursery stock a thorough check (including pots or other containers), especially if the plants have tags that indicate they are from Pennsylvania, New Jersey, or other SLF-infested states, and report any finds.
