Great Lakes Fishery Commission.

The Great Lakes Fishery Commission today reported that populations of the invasive, parasitic sea lamprey remain at near-historic lows, below targets, in Lakes Michigan and Ontario, and above target, but holding steady, in Lakes Huron, Superior and Erie. Sea lamprey populations in Lake Huron are close to target levels and have been holding steady for the past five years. Abundances in Lakes Superior and Erie remain above target but have also decreased significantly since the near-record highs observed in 2017. Sea lampreys are the worst of the alien species to invade the Great Lakes. Before control, sea lampreys destroyed many times the human fish catch. Today, sea lamprey control is the foundation of the $7 billion Great Lakes fishery. The Commission and its partners are encouraged by the overall decrease in abundance of sea lampreys throughout the Great Lakes basin during 2019, but caution that environmental conditions, such as a prolonged spring and high precipitation events, contributed to the decrease.

Seaplanes and Aquatic Invasive Species.

Reducing the potential to spread aquatic invasive species via the seaplane pathway. This project is intended to help the Aquatic Nuisance Species (ANS) Task Force reduce the risk of impacts of aquatic invasive species through the seaplane pathway by engaging with seaplane pilots and seaplane/seaplane equipment manufacturers in the lower 48 and Alaska to help prevent the introduction and spread of aquatic invasive species; improve the ability of seaplane pilots to lessen the spread of aquatic invasive species by developing best management practices that will be accepted and used by pilots; assessing the risk of aquatic invasive species spread by the seaplane pathway in different regions of the U.S. and compiling and sharing all information garnered through this research. A project funded by the U.S. Fish and Wildlife Service and implemented by various partners (Creative Resource Strategies, LLC, Pacific States Marine Fisheries Commission, Sea Grant and Conservation Collaborations).

Seed banks can provide insight into a forest’s past and give land managers valuable information to help them plan for the forest’s future. For example, knowing which species may germinate after future fires is valuable, especially when nonnative invasive species in the seed bank could proliferate quickly following disturbances.

In this study, researchers analyzed the species composition of buried seeds and extant vegetation present in areas that have faced differing fire conditions over many years on the Monongahela National Forest in West Virginia.

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.

Injurious wildlife provision of the Lacey Act provides effective tool to halt the introduction and spread of species that have been identified as imminent and serious threats. The U.S. Fish and Wildlife Service took action to help ensure 10 nonnative freshwater fish species and one nonnative freshwater crayfish species do not become established in the United States and damage native wildlife and habitats.

The U.S. Fish and Wildlife Service is announcing a $100,000 challenge to combat white-nose syndrome (WNS), a lethal fungus that has killed millions of bats in North America and pushed some native bat species to the brink of extinction. Funding will be awarded to individuals who identify innovative ways to permanently eradicate, weaken or disarm the disease.

There is no known cure for white-nose syndrome, but scientists worldwide are working together to study the disease and how it can be controlled. Much of this work has been conducted under the umbrella of the U.S. National Response to White-nose Syndrome, a broad, multi-agency effort led by the Service.

The deadline for individuals or teams to enter the challenge was Dec.31, 2019. Winning ideas will be the focus of future collaborations with scientists, designers and engineers to bring solutions to life. Additional information regarding rules and eligibility is available at White-nose Syndrome Challenge.

The U.S. Fish and Wildlife Service announced a proposal to list the tricolored bat as endangered under the Endangered Species Act (ESA). The species faces extinction due primarily to the range-wide impacts of white-nose syndrome, a deadly disease affecting cave-dwelling bats across the continent.

Bats are essential for healthy ecosystems and contribute at least $3 billion annually to the U.S. agriculture economy through pest control and pollination. The growing extinction crisis highlights the importance of the ESA and efforts to conserve species before declines become irreversible.

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.

According to Agricultural Research Service (ARS) entomologist and research leader Tracy Leskey, laboratory trials show that brown marmorated stink bugs are attracted to blue lights—lights that attract fewer non-target insect species. She also tested a combination of visually attractive blue lights with chemically attractive pheromones. These studies about the effectiveness of both light and pheromone-baited traps will help researchers develop more effective stink bug traps in the future.
