  1. Asian Longhorned Beetle Early Detection Prepared by Gary Watson and Angela Hewitt Funded by a grant from Version 1.0

  2. How does ALB get to the US? • Native to China, Korea, Taiwan • Larvae are transported in solid wood packing materials and shipped to businesses across the U.S.

  3. Known infestations • Infestations were discovered in New York in 1996, and Chicago in 1998

  4. Illinois Infested Trees 98-99 99-00 00-01 01-02 Total Ravenswood 837 472 100 5 1474 Addison 41 15 2 0 59 Summit 8 17 0 0 25 Park Ridge 4 3 0 7 O'Hare 23 0 23 Total 886 508 128 5 1527 Tree loses in N.E. Illinois Data as of 1/18/2002 ALB went undetected in the Chicago neighborhood of Ravenswood for 7 years

  5. The Detection Challenge 9 months 3months ALB Life Cycle

  6. Life Cycle ADULT • Anoplophora glabripennis • 0.75-1.25 inches in length • Emerge from July-October • Live approximately 45-60 days, • Can fly up to a mile

  7. Life Cycle • EGGS • hatch in approximately 11 days • Females are capable of laying up to 90 eggs

  8. Life Cycle LARVA • Feeds underneath bark and then tunnels into center of tree Late Larval feeding Damage Early Larval feeding Damage

  9. Life Cycle PUPA • 19-21 days

  10. Host Trees • Prefers • Maples (Acer spp.) • Will also infest • Horsechestnut (Aesculus hippocastanum) • Elms (Ulmus spp.) • Birches (Betula spp.) • Willows (Salix spp.) • Poplars (Populus spp.) • and many others

  11. Why Eradication? ALB could be as devastating as Dutch elm disease 61% of the trees in Chicago are susceptible to ALB with a value of over a billion dollars

  12. Eradication Program • Tree survey • Tree removal • Quarantine • Replanting

  13. Tree Survey • Ground • Bucket trucks • Climbers

  14. Tree Removal • Northeast Illinois area - 1,522 trees removed • New York City area - 5,297 trees removed

  15. Quarantine Regulatory procedures prevent the movement of infested wood to other areas

  16. Replanting Strategies • Resistant Species • Diverse plantings • Some resistant species • Ginkgo (Ginkgo biloba) • Catalpa (Catalpa spp.)

  17. Five Things to Look For • ADULT • EXIT HOLES • EGG SITES • FRASS • SAP FLOW

  18. What to Look For • ADULT • Glossy black with irregular white dots, antenna banded with black and white stripes • 0.75 – 1.25 inches in length • Seen July-October

  19. What to Look For • EXIT HOLES • 3/8 inch in diameter • Found predominantly on branches and limbs Growth over exit hole

  20. What to Look For • EGG SITE • oval to round and can be up to ½ inch across

  21. What to Look For • FRASScollects on branches and ground.

  22. What to Look For • SAP FLOW in the spring

  23. Other Longhorned Beetles Cottonwood Borer Whitespotted Pine Sawyer ALB

  24. What to do if you find a beetle? • Capture at least 1 adult beetle • Preserve in 70% alcohol, or put in freezer • In Chicago Call: • USDA – Chicago (312) 742-3386 • Illinois Department of Agriculture 1-800-641-3934
