  1. Invasive Species – Coming to America

  2. Exotic insects - a growing problem • >1,554 exotic insect species in U.S. • >4,500 exotic arthropod species in U.S. • Increase due to international trade and travel From R. Venette, USDA FS

  3. Invasive species – not just insects • Plants • aquatic • terrestrial • Animals • insects • fish • amphibians • birds • mammals • Pathogens

  4. Meaning of “Invasive” Polydrusus spp. • Species non-native to an environment may be called: • Alien • Exotic • Introduced • If they also cause harm to the economy, environment and / or human health they are called: • Invasive • Native species are not called invasive even if they do cause harm Steve Katovich USDA Forest Serivce Emerald ash borer Jeff Hahn, University of Minnesota Bronze birch borer Steve Katovich USDA Forest Serivce

  5. Invasive Species of Concern for Minnesota • Plants • Cut-leaved teasel • Dalmation toadflax • Yellow star thistle • Grecian foxglove • Black swallow-wort • Japanese knotweed • Survey • Visual surveys

  6. Invasive Species of Concern for Minnesota • Pathogens / nematodes • Potato cyst nematode • Soybean rust • Sudden oak death • Monitoring • Soil / plant tissue collection • Laboratory analysis

  7. Invasive Species of Concern for Minnesota • Insects • Emerald ash borer • Gypsy moth • European woodwasp • Light brown apple moth • Asian longhorned beetle • Exotic bark & ambrosia beetles • Swede midge • Survey • Traps baited with pheromone or other attractant

  8. What if I Find an Invasive Species of Concern? • Samples can be sent to: • Insects & Plants • "Arrest the Pest" Hotline651-201-6684 - Metro Area 1-888-545-6684 - Greater MinnesotaArrest.The.Pest@state.mn.us • Pathogens • U of M Plant Disease Clinic • Notify before sending

  13. Invasive Species Action Spectrum

  14. Prevention • Education • Inform public how invasive species are moved • Regulation • Legal actions such as inspection and quarantine

  15. Invasive Species Action Spectrum

  16. Early Detection • Surveys • Risk-based • Monitoring • Firewood & Nursery inspection • Citizen reports • First Detector Network • Arrest the Pest Hotline

  17. Invasive Species Action Spectrum

  18. Rapid Response • Emergency Quarantine • Stop artificial spread • Delimiting and Investigation • Determine the scale • Determine the source • Eradication or Suppression • Mitigate as able
