<strong>Asian</strong> longhorned beetle<br />
• Originally from China and Korea<br />
• First found in: Brooklyn 1996<br />
– 1998 Chicago<br />
– 2002-‐04 New Jersey (3 loca3ons)<br />
– 2008 Worcestor County,<br />
MassachuseNs<br />
– 2010 Clermont County, Ohio
<strong>Asian</strong> <strong>Longhorn</strong>ed beetle<br />
• Eradicated:<br />
– 2008 Chicago<br />
• Hudson Co., NJ<br />
– 2011 Islip, NY
• Intercepted in 17 states, including California<br />
and Washington
How do we find it early?<br />
• Traps and lures?<br />

ALB Training Simula3on Course
Training is very beneficial<br />
• 2 courses<br />
– 1 st 3me 16% passage<br />
– 2 nd 3me 80% passed
What happens then?<br />
• Mechanical control<br />
• Chemical control
• Imidacloprid<br />
Chemical control<br />
• Trunk and/or soil injec3ons<br />
• Start in March/April<br />
– May treat through July under the right<br />
condi3ons<br />
• Will not save infested trees<br />
• Protects trees from aNack
• Cut<br />
• Chip<br />
• Replant non-‐host<br />
Mechanical control
The Best Op3on<br />
• Don’t let it get here in the first place!<br />
– Only inspect ~2% of imports<br />
– Good SWPM treatment rules<br />
• Interna>onal Plant Protec>on Conven>on-‐ based on<br />
EAB a subcor>cal pest!<br />
• Several incidents of blatant problems<br />
• Must be enforced<br />
– Tighter controls on wood movement in the US<br />
– Especially firewood (but also one of the most difficult to<br />
regulate)<br />
– OR Rule: Firewood restric>ons to prevent<br />
transport of invasive species (ORS 603-‐052-‐1080)
It doesn’t stop here<br />
• The list of new exo3c pests is long. Our<br />
lax efforts will result in establishment of<br />
these pests eventually. Others to look for<br />
in the future:<br />
– Tremex woodwasps<br />
– Redbay ambrosia beetle (Xyleborus<br />
glabratus)<br />
– European woodwasp (Sirex noc5lio)<br />
– And . . .
If you are unsure, give the ODA a call!
Risks we’re unaccustomed to<br />
• Red turpen>ne beetle (Dendroctonus<br />
valens) in China
