  • A Nuclear Technique Averts a Fruit Fly Emergency in Mexico

    • Jun 17, 2022
    • UN. Food and Agriculture Organization.

    • In the Mexican state of Colima, a recent outbreak of the Mediterranean fruit fly, also known as medfly, was very bad news. This voracious pest was eradicated in Mexico in the 1980s with the help of FAO and the International Atomic Energy Agency (IAEA), but insects know no borders. And unfortunately, with climate change, increase of trade and global travel favouring the spread of pests, they have once more found their way into this horticulturally important state, threatening to wreak havoc on the industry and on the livelihoods of farmers. Thankfully, Mexico, FAO and the IAEA had prepared for just a scenario.

  • Alien Species in the Cayman Islands

    • The new (Alien Species) Regulations 2022 recently passed by Cabinet will ensure greater protections for Cayman's most precious native flora and fauna (plants and animals) with the creation of a prohibited species list, and differentiating between domestic & feral species. The legislation also provides ways to control feral and alien species, crucial to reducing threats to both pets as well as our native species.

  • USDA Under Secretary Jenny Lester Moffitt Visits Mexico to Celebrate 75 Years of Mexico-U.S. Commission for Prevention of Foot-and-Mouth Disease and Other Exotic Animal Diseases

    • May 25, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • The U.S. Department of Agriculture’s (USDA) Under Secretary for Marketing and Regulatory Programs Jenny L. Moffitt commemorates the 75th anniversary of the Mexico-U.S. Commission for Prevention of Foot-and-Mouth Disease and Other Exotic Animal Diseases (CPA). To celebrate this occasion, Mexico’s National Agro-Alimentary Health, Safety, and Quality Service (SENASICA) hosted a celebration in Mexico City. This binational Commission, established in 1947, was instrumental in eradicating foot-and-mouth disease (FMD) in Mexico and preventing introduction to the United States. FMD was eradicated from the United States in 1929, and Mexico has been FMD-free since 1954. This celebration honors the longevity and success of this collaboration between the United States and Mexico.

  • USDA Continuing African Swine Fever Prevention Efforts – Preparing to Establish Foreign Animal Disease Protection Zone

    • Aug 26, 2021
    • USDA. Animal and Plant Health Inspection Service.

    • As part of its continuing efforts to respond to the detection of African Swine Fever (ASF) in the Dominican Republic (DR) and prevent its introduction into the Conterminous United States, Puerto Rico, and the U.S. Virgin Islands, the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is preparing to establish a Foreign Animal Disease protection zone in Puerto Rico and the U.S. Virgin Islands. ASF has not been detected in Puerto Rico or the U.S. Virgin Islands, and USDA is committed to keeping it out of both islands and the rest of the United States. Out of an abundance of caution, APHIS is taking this additional action to further safeguard the U.S. swine herd and protect the interests and livelihoods of U.S. pork producers.

  • CABI Highlights Top 20 Crop Pests and Diseases for Possible Prioritization in the Eastern Caribbean

    • Sep 20, 2021
    • CAB International. Invasives Blog.

    • CABI has highlighted the top 20 crop pests and diseases for possible prioritization in the Eastern Caribbean as part of a special presentation given to the Caribbean Plant Health Directors Forum (CPHD) aimed at strengthening food security in the region and further afield. Dr Yelitza Colmenarez, CABI’s Centre Director, Brazil, told the conference of CPHD – with the participation of key partners including the FAO, IICA, OIRSA, USDA-APHIS, CIRAD, CARDI, CAHFSA and CABI Member Countries from the Caribbean – that the introduction of new pest and pathogen species are a serious threat to food security within the Organisation of Eastern Caribbean States (OECS) and globally. With the help of a range of CABI tools and platforms, including the Crop Protection Compendium, Invasive Species Compendium, Horizon Scanning Tool and Pest Risk Analysis Tool, Dr. Colmenarez says 20 key insects, bacteria, fungus and viruses pose a particular threat that needs to be identified, monitored and mitigated.

  • Canadian Minister of Transport Announces New Regulations to Help Prevent Spread of Aquatic Invasive Species in Canada

    • Jun 23, 2021
    • Transport Canada.

    • Canada's coasts and waterways are vital to our environment, livelihoods, and economy, and must be protected. Ballast water, which helps keep vessels stable in the water, can accidentally introduce and spread aquatic invasive species, like the zebra mussel, if released in the water untreated. To further protect Canadian waters, the Government of Canada is taking action to limit the introduction and spread of aquatic invasive species in ballast water. Today, the Canadian Minister of Transport announced the coming into force of the new Ballast Water Regulations to strengthen existing rules for vessels on international voyages and the introduction of new rules for vessels which remain in Canada and on the Great Lakes. These regulations, which replace the Ballast Water Control and Management Regulations, apply to vessels in Canadian waters and to Canadian vessels anywhere in the world. Vessels are now required to:

      • plan their ballast water management and reduce the number of organisms in their ballast water, typically by installing a ballast water management system; and
      • carry a valid certificate, keep records, and be regularly surveyed and inspected. Smaller vessels may follow an equivalent approach tailored to their operations and size.

  • Government of Canada Invests $14.7M in Conservation Projects in Five Mountain National Parks to Prevent and Manage Aquatic Invasive Species

    • Dec 4, 2021
    • Parks Canada.

    • On Dec 4, 2021, the Minister of Environment and Climate Change and Minister responsible for Parks Canada, the Honourable Steven Guilbeault, announced federal investments of $14.7 million over the next five years for conservation projects to prevent and manage aquatic invasive species in Banff, Jasper, Kootenay, Waterton Lakes and Yoho national parks.

      The mountain national parks are particularly vulnerable to aquatic invasive species due to the high amount of water recreationists who visit each year. Aquatic invasive species alter aquatic ecosystems, cause irreversible damage, impact vulnerable species at risk, and spread downstream beyond park boundaries through the interconnected river systems. Of particular concern for the mountain national parks are invasive mussels, which deplete available nutrients and in turn affects the entire food web by altering water chemistry and quality, as well as the parasite that causes whirling disease, which leads to skeletal deformities for native species. This investment will help address major threats to aquatic ecosystems by funding programs to prevent and educate against the spread of aquatic invasive species.

  • Canal Grass: Smithsonian Scientist Clears Up Panamanian Urban Legend

    • Nov 30, 2020
    • Smithsonian Institution. Smithsonian Tropical Research Institute.

    • Urban legends about the origins of canal grass in Panama abound, but the Smithsonian has new evidence that puts the question to rest. Canal grass is an invasive weed, native to Asia. Because its tiny seeds blow in the wind, it readily invades clearings and spreads to form impenetrable stands by budding from tillers and rhizomes. Once established, canal grass is challenging to eliminate.

  • Panama Canal: Superhighway for Invasive Species?

    • Feb 25, 2015
    • National Geographic.

    • When the expansion of the Panama Canal is completed in 2016, giant ships that now must dock at West Coast ports after crossing the Pacific will be able to deliver cargo directly to ports on the Gulf of Mexico and the East Coast. One thing they may be delivering, according to a recent study, is a much larger number of alien species.

  • Latest Emerald Ash Borer Detections

    • Canadian Food Inspection Agency.

    • The emerald ash borer (EAB) is a highly destructive invasive beetle which attacks and kills all species of ash, but not mountain ash, which in spite of its name, is a completely different species of tree. To help prevent the spread of EAB, the movement of ash logs and firewood out of regulated areas is restricted. Report any detections outside of regulated areas to one of the CFIA's offices.
