Arkansas Department of Agriculture.

The Arkansas Department of Agriculture is pleased to announce the release of the newly created Arkansas Feral Hog Handbook, a guide to resources available in Arkansas to assist with feral hog control and eradication. The handbook includes contact information, websites, and brief explanations of the resources offered by state and federal agencies and other entities. "The Arkansas Feral Hog Handbook was made possible through a grant funded by the United States Department of Agriculture's Natural Resources Conservation Service. We appreciate their partnership and the information provided by other Feral Hog Eradication Task Force members to make the handbook a comprehensive educational resource for Arkansans," said Arkansas Secretary of Agriculture Wes Ward.

The handbooks are being distributed to the public at locations throughout the state with assistance from partner organizations, including the Arkansas Association of Conservation Districts, University of Arkansas Cooperative Extension Service, Arkansas Game and Fish, and Arkansas Farm Bureau. Copies of the handbook can be requested at lori.scott-nakai@arkansas.gov. An online version (2020; PDF | 4.48 MB) is also available.

The Asian longhorned tick, which preys on a variety of hosts including humans and wild and domestic animals, has been found in Kentucky. This new tick is known to attack animals in large numbers and will be a concern to livestock producers, wildlife enthusiasts and pet owners. The tick has been found in small numbers on elk in Martin County and black bear in Floyd County. It was found in large numbers on a bull in Metcalfe County in the south-central part of the state. Individuals who find a usually large number of ticks on their pet or livestock should contact their local veterinarian. Those who find single ticks they think might be an Asian longhorned tick should work with their county extension agent for agriculture and natural resources to submit the sample to UK entomologists for positive identification.

White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

New York State Department of Environmental Conservation.

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today confirmed that spotted lanternfly (SLF), an invasive pest from Asia, has been found in Albany and Yates counties. A single adult insect was discovered in a vehicle in the Capital District. In addition, a single adult insect was reported on a private Keuka Lake property in Penn Yan, Yates County. Anyone that suspects they have found SLF is encouraged to send a photo to spottedlanternfly@dec.ny.gov. Please note the location of where the insect was found, egg masses, and/or infestation signs. DEC and DAM also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.

New York State Department of Environmental Conservation.

The New York State Departments of Environmental Conservation (DEC) and Agriculture and Markets (DAM) today announced that although freezing temperatures will kill off adult spotted lanternflies (SLF), the public is urged to stay vigilant and report overwintering egg masses. In the fall, SLF will lay their eggs on any flat surface such as vehicles, firewood, outdoor furniture, stone or other items which can be inadvertently transported to new areas. If this insect becomes established in New York, it could impact New York's forests, agricultural and tourism industries. "To date, there has not been a documented spotted lanternfly infestation in New York, but I encourage the public to stay aware and be ready to report egg masses or other signs of this insect to help prevent infestations," said DEC Commissioner Basil Seggos.

Assistance from the public is crucial in limiting the movement of SLF and protecting New York's natural resources. DEC and DAM are urging the public to inspect outdoor items such as vehicles, outdoor furniture and camping equipment for egg masses or insects, and report any sightings by sending photos and location information to spottedlanternfly@dec.ny.gov. Anyone that visits locations of SLF quarantines in other states should look for and remove insects and egg masses on items before leaving those areas. For more information, please visit DEC's spotted lanternfly webpage.

University of Guam.

The University of Guam received another round of funding in September under the U.S. Department of Agriculture Plant Protection Act for the surveying and monitoring of invasive pests of solanaceous crops that are on USDA’s Priority Pest List for 2021. Solanaceae, or nightshades, are a family of flowering plants that include tomato, eggplant, and chili pepper. As part of the national effort this year, UOG was awarded $38,000 to survey and monitor for two pests: Tuta absoluta, which is a moth and type of leafminer capable of destroying an entire crop, and Ralstonia solanacearum race 3 biovar 2, which is a bacterium, known as a bacterial wilt, that infects through the roots and is deadly to plants.

The work through UOG better prepares the island to manage these invasive species if or when they arrive. "There are certain pathogens and insects that have a reputation of being really bad. These are two of them," said project lead Robert L. Schlub, a researcher and faculty member of UOG Cooperative Extension and Outreach with a doctorate in plant pathology. "They aren’t on Guam, but if they show up, we want to know so we can help get them under control."

On Tuesday, June 5, 2018, the United States Department of Agriculture (USDA) National Veterinary Services Laboratory (NVSL) confirmed the presence of the Longhorned tick (Haemaphysalis longicornis) in Arkansas. The Longhorned tick is an exotic East Asian tick associated with bacterial and viral tickborne diseases of animals and humans in other parts of the world. This tick is considered by USDA to be a serious threat to livestock because heavy tick infestations may cause stunted growth, decreased production and animal deaths. Like deer-ticks, the nymphs of the Longhorned tick are very small (resembling tiny spiders) and can easily go unnoticed on animals and people. This tick is known to infest a wide range of species and has the potential to infect multiple North American wildlife species, humans, dogs, cats, and livestock.

New York State. Governor Andew Cuomo.

Funding Supports Invasive Species Rapid Response and Control, Research, Lake Management Planning, and Aquatic Invasive Species Spread Prevention Programs. Governor Andrew M. Cuomo today announced more than $2.8 million in grants have been awarded to 42 projects that will reduce the negative impacts of invasive species through control or removal activities, research, and spread prevention. These grants are part of the State Department of Environmental Conservation's Invasive Species Grant Program and are funded by the State's Environmental Protection Fund.  

State of Wyoming.

Reflecting his goal of making Wyoming a national leader in the battle against invasive species, Governor Mark Gordon announced today he has launched an initiative to address terrestrial invasive plants in the state. The initiative will be comprised of two teams -- a Policy Team and a Technical Team, each comprised of local, state and federal government representatives, private citizens representing industry and agricultural groups, as well as scientists and practitioners. The two teams will work cooperatively to develop recommendations for the Governor in the context of a large-scale strategy for invasive species management. Terrestrial invasive species represent a significant threat to Wyoming’s forests, rangelands and agricultural lands with varying levels of impact.

For the first time, an invasive brown treesnake population has been found on Cocos Island, an 83.1 acre atoll located 1.5 miles off the southwest coast of Guam. The brown treesnake was a major contributor to the loss of nine of 11 native forest birds and significant population declines of several native lizards, bats and other bird species on Guam. They now pose a threat to the wildlife of Cocos Island. Guam Department of Agriculture Division of Aquatic and Wildlife Resources is working with partners to better understand how many brown treesnakes are on the island and the best way to remove them.

Idaho watercraft inspectors have identified  zebra mussels on a commercially hauled sailboat destined for Lake Coeur d’Alene in the state’s northern panhandle, marking the first time the invasive species has been found live this year.

Arkansas Game & Fish Commission.

Another documented report of giant salvinia along the Texas-Arkansas border was confirmed by Texas Parks and Wildlife last week, creating additional concern from Arkansas Game and Fish Commission biologists about the nuisance plant's spread into The Natural State. Giant Salvinia is a free-floating South American plant, similar in appearance to duckweed but much larger. It stays at the water's surface and can rapidly cover a large area and choke out all life in the water beneath if left unchecked. Arkansas's first confirmed case of giant salvinia entering the state was documented in 2017 in Smith Park Lake in Miller County followed shortly after by sightings in Sulphur River Wildlife Management Area. It was confirmed in Lake Erling in December 2018 and Lake Columbia in 2019. Anyone spotting giant salvinia in an Arkansas lake is encouraged to call the AGFC's Fisheries Division at 800-364-4263 to report the location.

Cornell University. College of Agriculture and Life Sciences.

For the last seven decades, Cornell University’s College of Agriculture and Life Sciences (CALS) has been leading the fight against nematodes—invasive, microscopic worms that can destroy seasons' worth of crops. However, researchers had been working in a facility that lacked the infrastructure to keep pace with their innovative work. On August 1, 2019, thanks to a $1.2 million grant from New York State and another $400,000 in federal funding, CALS cut the ribbon on the new Golden Nematode Quarantine Facility, located on the Cornell campus in Ithaca, NY. The facility is the only research program in North America with expertise in biology, resistance breeding and management of potato-cyst nematodes. At the lab, Cornell scientists work in tandem with the U.S. Department of Agriculture (USDA) Agriculture Research Service (ARS).

For landscapes plagued by autumn olive or entangled in oriental bittersweet, a new website offers help identifying and managing woody invasive plants like these. WoodyInvasives.org, developed by the Woody Invasives of the Great Lakes Collaborative, contains a wealth of information about how to distinguish woody invasive species from similar beneficial plants, an interactive map showing how these species are regulated by Great Lakes jurisdictions, detailed management approaches and noninvasive woody plant ideas for gardeners and landscape designers. "We developed the WIGL Collaborative website to help people learn to identify the woody invasive plants around them and to feel empowered to start controlling them on their properties or in their favorite green places," said Clair Ryan, coordinator of the Midwest Invasive Plant Network, the organization leading the effort.

New York State Department of Environmental Conservation.

New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today encouraged anglers in the Delaware River to be on the lookout for northern snakehead, an invasive fish native to Southeast Asia. A northern snakehead was recently caught in the Callicoon area of the Delaware River. Given the right environmental conditions, this invasive species can prey on and compete with other fish, upsetting the natural balance of local ecosystems. "Northern snakeheads are listed federally as injurious wildlife, and New York State law prohibits their live possession," Commissioner Seggos said. "Any snakehead caught should be killed immediately and not released back into the water." In the event an angler catches a northern snakehead, DEC advises anglers to report the catch to the regional NYS DEC fisheries office, DEC's Invasive Species Bureau at isinfo@dec.ny.gov or (518) 402-9425, or submit a report through iMapinvasives.

North Dakota Department of Agriculture.
Palmer amaranth (Amaranthus palmeri), an aggressive pigweed species similar in appearance to waterhemp, has been positively identified for the first time in North Dakota in McIntosh County. Palmer amaranth is native to the southwestern U.S. but was accidentally introduced to other areas and has devastated crops in the South and Midwest. It had not been identified in North Dakota until now. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on Palmer amaranth and other noxious and invasive weeds is available here. To report a suspect plant, contact the North Dakota Department of Agriculture at 701-328-2250 or North Dakota State University Extension at 701-231-8157 or 701-857-7677.
North Dakota Department of Agriculture.
Palmer amaranth (Amaranthus palmeri) and houndstongue (Cynoglossum officinale L.) have been added to the state noxious weed list. Palmer amaranth is an aggressive pigweed species similar in appearance to waterhemp and was first found in the state last year. It has now been found in five counties. Houndstongue, which does not spread aggressively like Palmer amaranth, has been found in North Dakota since at least 1911 but infestations have tripled since 2008. It is now found in at least 25 counties. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on these and other noxious and invasive weeds is available at https://www.nd.gov/ndda/plant-industries/noxious-weeds.
