Dogs specially trained by Agricultural Research Service (ARS) scientists have proven to be the most efficient way to detect huanglongbing—also known as citrus greening—according to a paper just published in the Proceedings of the National Academy of Sciences. Currently, the only solid hope of curtailing the spread of citrus greening is to eliminate trees with the disease as quickly as possible to prevent further spread. Early detection of the citrus greening pathogen is crucial because trees can be infected and act as a source to spread the disease months or years before showing symptoms that are detectable by the naked eye. ARS plant epidemiologist Timothy R. Gottwald with the U.S. Horticultural Research Laboratory in Fort Pierce, Florida, discovered that dogs can be trained to sniff out the presence of Candidatus Liberibacter asiaticus, the bacteria that causes citrus greening, with greater than 99 percent accuracy.

A unique program run by the Agricultural Research Service in Fort Pierce, FL, uses specially trained dogs to detect citrus greening in orchards. The canine-detection method has an accuracy rate of 99 percent.

USGS has published, and plans to update on a bimonthly basis into the foreseeable future, a dataset called "Catalog of U.S. Federal Early Detection/Rapid Response Invasive Species Databases and Tools." The catalog, developed in collaboration with the National Invasive Species Council Secretariat, is a multi-sheet spreadsheet that contains openly available, online, federally supported databases and tools dealing with various aspects of a potential national early detection and rapid response invasive species framework.

Invasive zebra and quagga mussels are an immediate threat to Western states. With no controls, they spread rapidly, foul boats and equipment, clog water intake, and increase costs to hydropower operations and municipal water utilities. Even dead mussels can be a nuisance, littering beaches with shells. Management of these invaders is expensive; in the Great Lakes, managing mussels costs about $500 million annually. Until 2007, the mussels were limited to waterways and lakes east of the Mississippi, but now they have spread westward. In 2016, quagga mussels were found in Lake Powell.
Unfortunately, there are no foolproof existing technologies or treatments to eradicate established mussel populations in large, open water systems in an environmentally sound manner. Early warning, however, helps us prepare before the mussels or other invasive species arrive.
USDA. Forest Service.
In partnership with USDA Forest Service, Wildlife Forever recently unveiled a new Clean Drain Dry Rapid Response Communication Kit (PDF | 4.4 MB) to help communities with invasive species. Informing the public is critical in slowing the spread. The readymade communication tools are designed for immediate distribution or can be customized to local needs. Prevention is still the best way to slow the spread and this Rapid Response Kit is designed to do this in two ways:
- Send out an urgent warning that a local lake has been infested with a specific Aquatic Invasive Species
- Educate the affected public as to what they can – and should – do to help prevent further spread of the species

Researchers from Dickinson College and the U.S. Geological Survey collaborated on field research to understand the ability of human searchers to detect the invasive brown treesnake (BTS) on the island of Guam. Due to their nocturnal and tree-dwelling habits, these snakes are extremely difficult to detect, especially when they are present at low densities in an area. A new study published in the journal Ecosphere helps explain why and provides valuable information on optimizing search methods and search locations that could be valuable if the BTS was accidentally introduced to a snake-free island.
United States Department of the Interior.
The Administration announced a new interagency conservation agreement to protect western water supplies, power generation, outdoor recreation and aquatic ecosystems by strengthening efforts to combat invasive mussels.
A Memorandum of Understanding (MOU) among the U.S. Army Corps of Engineers, U.S. Department of Agriculture Forest Service, and six Department of the Interior bureaus focuses on boosting federal coordination, communication and collaboration to enhance the capacity of federal, state and tribal agencies to rapidly respond to discoveries of invasive mussels in western states.
USDA. Animal and Plant Health Inspection Service.
The U.S. Department of Agriculture (USDA) is allocating more than $70 million to support 383 projects under the Plant Protection Act’s Section 7721 program to strengthen the nation’s infrastructure for pest detection and surveillance, identification, threat mitigation, to safeguard the nursery production system and to respond to plant pest emergencies. Universities, states, federal agencies, nongovernmental organizations, nonprofits, and Tribal organizations will carry out selected projects in 49 states, the District of Columbia, Guam, and Puerto Rico.
The fiscal year 2021 project list includes 29 projects funded through the National Clean Plant Network (NCPN). The NCPN helps our country maintain the infrastructure necessary to ensure that pathogen-free, disease-free and pest-free certified planting materials for fruit trees, grapes, berries, citrus, hops, sweet potatoes, and roses are available to U.S. specialty crop producers. In FY 2021, funded projects include, among others:
- Asian giant hornet research and eradication efforts: $944,116 in Washington and other states;
- Exotic fruit fly survey and detection: $5,575,000 in Florida and California;
- Agriculture detector dog teams: $4,287,097 to programs in California, Florida, and nationally to support detector dog teams;
- Honey bee and pollinator health: $1,337,819 to protect honey bees, bumble bees and other important pollinators from harmful pests;
- Phytophthora ramorum (sudden oak death pathogen) and related species: $513,497 in 14 states and nationally for survey, diagnostics, mitigation, probability modeling, genetic analysis, and outreach;
USDA will use $14 million to rapidly respond to invasive pest emergencies should a pest of high economic consequence be found in the United States.

Natural resource managers in British Columbia discovered several adult male and female European green crabs on Haida Gwaii this past July. Alarm bells immediately went off for biologists in Alaska. The archipelago of Haida Gwaii, off the coast of Prince Rupert in British Columbia, is very close to Alaska. The July discovery is the closest confirmed finding of the invasive crustacean since it was first detected in the San Francisco Bay area in 1989.
