2 Asian Longhorned Beetle Topics Introduction into the U.S. Survey Regulatory Management

3 What is the Asian Longhorned Beetle (ALB)? an uninvited guest in our community Native to Asia Wood-boring beetle KILLS TREES!! No predators in North America No effective means of chemical control

4 What is the Asian Longhorned Beetle (ALB)? If left unchecked, economic damage is estimated at more than $600 billion if ALB becomes established Numerous industries affected: Tourism Sugar maple industry Timber industry Nursery stock industry

5 How did ALB get here?

6 Solid Wood Packing Material December 1998, USDA amended regulations to require treatment or fumigation of all SWPM from China to prevent further introduction of exotic wood boring pests. (SWPM)

7 Solid Wood Packing Material (SWPM) International Plant Protection Convention stamp from China; DBMB stands for Fumigation with methyl bromide.

8 North American ALB Infestations

9 Survey Host Tree Inspections Ground Climbing Bucket Truck

10 The most commonly used approach utilizes specialized ground surveyors equipped with binoculars to locate signs of ALB damage on a tree According to USDA environmental assessment reports, accuracy of detection by ground surveyors is about 30% as determined by quality assurance checks

11 All host trees on public and private property located within an established distance from an infested area are surveyed by trained personnel. Infested areas are re-surveyed at least once per year for 3 5 years after the last beetle or infested tree is found.

12 Maple Birch Willow Elm Horsechestnut Sycamore/Plane tree Mountain Ash Hackberry Ash Poplar/Cottonwood Mimosa Katsura ALB Host Trees

13 Lure-baited traps can be used to detect ALB in the field.

14 Sniffer dogs have been trained to detect ALB in the United States and Europe. The dogs search residential trees, trees in wooded lots, and stacks of firewood

15 Increases awareness in order to facilitate program activities and compliance with regulations Public Outreach

16 Public Outreach General Tools Presentations at local festivals and events Meetings with community groups Advertisements in newspapers and magazines TV and radio advertising and interviews Mailings, door hangers, flyers

17 People Uncover Infestations The public is effective at finding new infestations People care about trees and the potential impact of an infestation

18 Regulatory Successful eradication efforts for the Asian longhorned beetle hinge on accurate and timely detection of infested trees, methods to kill the beetle in infested trees, and ways of preventing it from spreading.

19 Regulatory Quarantines have been established around infested areas to prevent accidental spread of ALB by people. Compliance Agreements with companies handling trees and woody debris

20 The quarantine restricts and prohibits: Any life stage of ALB the movement of firewood green lumber and other living /dead, cut or fallen material, including logs, stumps, branches, and nursery stock to outside of the quarantined area.

21 Tree Removal The most effective method to eradicate ALB is to completely remove and chip or burn infested trees and grind stumps. From 1998 to 2006, the costs to detect, remove, and prophylactically treat host trees with imidacloprid was $249 million dollars in the U.S. alone

22 Stump Grinding Stumps from infested trees will be ground to 8 inches below the surface

23 Wood Chips Host material must be chipped to less than 1 inch x 2 inch dimensions to be considered deregulated material. A U.S. Quarter is approximately 1 inch.

24 Management Research is underway to determine the effectiveness of certain insecticides such as imidacloprid and neonicotinoids against ALB as well as biocontrol agents including pathogens and parasitoids to effectively manage ALB.
