    • The $900,000 grant will help Virginia Tech researchers see if the spotted lanternfly can help spread a fungus that kills the tree-of-heaven. The goal of the grant is to develop a native fungus as a biocontrol for the tree-of-heaven. Researchers are investigating whether the spotted lanternfly could help transmit the fungus from tree to tree, reducing the need for human intervention.

  • Spotted Lanternfly Reveals a Potential Weakness

    • Jan 19, 2024
    • USDA. Blog.

    • USDA scientists have discovered that the spotted lanternfly, an invasive threat to fruit crops and many trees, may have an Achilles heel – an attraction to vibration. A native of China, the insect was discovered in Pennsylvania in 2014 and has since spread to 13 other states. Though beautiful as an adult, the insect is a voracious eater that feeds on woody and ornamental trees as well as a wide variety of crops and plants. Left unchecked, Pennsylvania alone could lose hundreds of millions of dollars and thousands of jobs.

      Richard Mankin, an entomologist with the USDA Agricultural Research Service’s Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, FL, and colleagues found a new way to potentially corral and control the pests. Their research was published in the Journal of Economic Entomology.

Damaging invasive insect species, such as spotted lanternfly, longhorned beetles, and emerald ash borer, are emerging in their adult form. ate summer is often the peak time for these invasive insects to emerge from trees in their adult stage. If you see or suspect you see an invasive insect, report a sighting.

APHIS brought together the working group in August 2022 with representatives from APHIS, the National Association of State Departments of Agriculture (NASDA) and the National Plant Board (NPB). The working group developed a unified approach to reduce the spotted lanternfly’s spread and impacts through the effective use of available State and Federal resources.

Photos are necessary to verify a report and to aid in identification.

  • Spotted Lanternfly Identified in Illinois

    • Sep 26, 2023
    • Illinois Department of Natural Resources.

    • The Illinois Department of Agriculture has confirmed the first detection of spotted lanternfly (Lycorma deliculata) in Illinois. Following a report of a live adult on Sept. 16, state, federal, and local officials coordinated a site visit near the area of the report and identified a moderately populated area of spotted lanternfly (SLF) on Sept. 18. Specimens were collected and submitted for identification, and confirmatory results were received on September 26. The spotted lanternfly does not present any human or animal health concerns.

      If you see SLF or suspect it, report it to lanternfly@illinois.edu. A fact sheet, including photos, is available through the University of Illinois Extension [PDF, 1.6 MB].

  • Iowa Department of Agriculture and Land Stewardship Urges Iowans to be on the Lookout for Spotted Lanternflies: Colorful but invasive and destructive insect has been confirmed in Iowa

    • Jul 26, 2022
    • Iowa Department of Agriculture and Land Stewardship.

    • The Iowa Department of Agriculture and Land Stewardship asks Iowans to be on the lookout for spotted lanternfly insects. The colorful but invasive and destructive insect is native to China, India, and Vietnam, and was accidentally introduced into Pennsylvania in 2014. It has since been confirmed in eleven states and often spreads by the movement of infested material or items containing spotted lanternfly egg masses. If allowed to spread further in the United States, this pest could seriously impact the country’s grape, orchard, nursery, and logging industries.

      A community member notified the Iowa Department of Agriculture and Land Stewardship of the presence of two immature spotted lanternflies in Dallas County earlier this month. Federal identification confirmed the sample as a spotted lanternfly. Surveys of the immediate area have not resulted in signs of an ongoing infestation and entomologists hope the insects recently hitchhiked into the area.

      If you think you have found a spotted lanternfly, please call the Entomology and Plant Science Bureau at 515-725-1470 or e-mail Entomology@IowaAgriculture.gov. You may also contact your local county Iowa State University Extension Office.

  • North Carolina Department of Agriculture and Consumer Services (NCDA&CS) Finds Spotted Lanternfly in Forsyth County: First Established Presence of the Pest in North Carolina

    • Jun 29, 2022
    • North Carolina State University. Cooperative Extension.

    • The North Carolina Department of Agriculture and Consumer Services has confirmed the first established presence of the invasive spotted lanternfly (Lycorma delicatula) in the state. Initial surveys indicate the known distribution of the pest is within a 5-mile radius in Forsyth County near Interstate 40 in Kernersville extending to the Guilford County line.

      Early detection and rapid response are critical in the control of spotted lanternfly and the Plant Industry Division has been preparing to provide the most effective response to slow the spread of this invasive pest in the state. If you see or suspect spotted lanternfly in North Carolina submit a picture through the Spotted Lanternfly Reporting Tool.

    • Maryland Department of Agriculture.

    • The Maryland Department of Agriculture has taken a significant step in its ongoing efforts to control the invasive spotted lanternfly. The department has announced the expansion of its spotted lanternfly quarantine zone to include two new counties – Charles and Garrett – effective immediately. This quarantine restricts the movement of regulated articles that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.

  • 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.
