  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. Invasive Species Action Spectrum

  9. David R. Lance, USDA APHIS PPQ Kenneth R. Law, USDA APHIS PPQ Pest Status = Absent Sirex Woodwasp Asian longhorned beetle Emerald Ash Borer

  10. Gyorgy Csoka, Hungary Forest Research Institute Kevin D. Arvin Pest Status = Present, not established Gypsy Moth Pine Shoot Beetle Japanese Beetle

  11. Steve Katovich, USDA Forest Service Pest Status = Established White Pine Blister Rust Common Buckthorn Dutch Elm Disease Maja Jurc, University of Ljubljana

  12. Invasive Species Action Spectrum

  13. Prevention • Pest Risk Assessment • Quantitative means to rate risk posed by various pests • Education • Inform public how invasive species are moved • Regulation • Legal actions such as inspection and quarantine

  14. Invasive Species Action Spectrum

  15. Early Detection • Surveys • Risk-based • Monitoring • Firewood & Nursery inspection • Citizen reports • Arrest the Pest Hotline

  16. Invasive Species Action Spectrum

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