  • California Establishes Quarantine to Prohibit the Introduction of the Spotted Lanternfly into California

    • Jul 16, 2021
    • California Department of Food and Agriculture.

    • A state exterior quarantine has been declared to prohibit the introduction of the spotted lanternfly (SLF), Lycorma delicatula, into California. Spotted lanternfly was first detected in North American in 2014 in Pennsylvania and has now spread to nine states. The quarantine prohibits the entry into California of SLF, its host plants, and a variety of articles, including conveyances, originating from any area where an SLF infestation exists.

      If you believe you have seen the spotted lanternfly, please contact CDFA's Invasive Species Hotline at 1-800-491-1899, via Report a Pest, or by contacting your local County Agricultural Commissioner.

  • Call 701-328-2655 to Report Feral Swine

    • North Dakota Department of Agriculture.

    • Feral swine are an invasive species which cause extensive damage to crops, property, and the environment. They are also known to carry over 30 diseases and 37 parasites that can be transmitted to livestock, people, pets, and wildlife. When feral swine are sighted in North Dakota, the State Board of Animal Health should be notified immediately. Attempts will be made to identify whether the swine are truly feral or if they are escaped domestic swine which are private property. Individuals who encounter feral swine should not destroy them unless they encounter feral swine on their own property and there is a threat of harm or destruction of property. As soon as possible following destruction of the animal, but always within 24 hours, the individual must notify the State Board of Animal Health (BoAH) at 701-328-2655.

  • Can Biocontrol Halt the Spread of Invasive Cogongrass?

    • May 23, 2024
    • USDA. ARS. Down on the Farm.

    • Currently, most cogongrass is controlled with herbicides, which only serve as a temporary solution. The herbicides must be reapplied every 6-12 months. ARS scientists in the U.S. and overseas are investigating biological control of cogongrass by collecting and studying insects that feed on the grass where the weed originated. These insects will be screened over many years to determine if they will be safe, and only those that cause no harm to valued plants will be released.

  • Canker Disease Threatens Louisiana’s Citrus Industry

    • Oct 11, 2018
    • Louisiana State University. AgCenter Research and Extension.

    • Citrus canker, a serious disease of citrus, was recently found on trees in East Baton Rouge and Livingston parishes, according to LSU AgCenter plant doctor Raj Singh. Citrus canker is a highly contagious bacterial disease that was first detected around 1914 in Louisiana and declared eradicated by 1940. The disease is known to cause defoliation, premature fruit drop, blemished fruit and tree decline. Severely infected trees ultimately may stop producing fruit. If you believe your citrus trees have citrus canker, contact the U.S. Department of Agriculture at 225-298-5410 or the LDAF Horticulture and Quarantine Division at 225-952-8100

  • CBP Field Ops Intercepts 90 Slimy Giant Snails at Detroit Metro

    • DHS. Customs and Border Protection.

    • The U.S. Customs and Border Protection’s (CBP) Office of Field Operations discovered 90 giant African land snails in a traveler’s luggage at Detroit Metropolitan Airport on June 30, 2024. The passenger had arrived from Ghana. The snails were seized and were “humanely euthanized,” the CBP says. The release says euthanizing the snails was necessary “to ensure they did not enter the ecosystem and cause havoc to U.S. agriculture.”
