USDA August is Tree Check Month: Check For Asian Beetle
USDA Observes August As Tree Check Month And Asks The Public To Take 10 Minutes To Check Trees For Asian Longhorned Beetle
USDA Washington, July 30, 2013 -- The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) today announces August is Tree Check Month and urges the public to check trees for signs of Asian longhorned beetle (ALB).
“August is a time of peak emergence for the beetle and is most likely when members of the public will see an adult beetle infesting trees,” states Scott Pfister, Director for USDA APHIS' Pest Management Division. “We’re asking people to take 10 minutes and check your trees for the beetle and any signs of damage it causes.”
Checking trees on your property or in your neighborhood means looking at the host trees the beetle attacks for the beetle itself or signs of damage caused by it. The most concerning signs are dime-sized exit holes, roughly ¼ inch or larger, perfectly round, found on the trunk and branches. You can look for round or oval shallow scars in the bark where the females chew oviposition (egg-laying) sites, and also for frass (excrement), a sawdust-like material, on the ground at the base of the tree or at the crotches of branches. Dead branches or canopy dieback can indicate something is wrong. Finally, look for the beetle itself on the tree trunk, branches, on the ground, and on nearby surfaces...
