The United States Department of Agriculture's Animal and Plant Health Inspection Service ( APHIS ) is urging the public to check their trees for signs of the Asian Longhorned Beetle. It is most active as an adult during the month of August into September.
This very invasive insect has been responsible for the loss of over 30,000 trees in one county alone in Massachusetts not to mention those lost already in our own neighboring Illinois and Ohio.
The following is an article re-printed from an earlier Newsletter.
HEY CUTIE!!!....
Pictured above is the very invasive Asian Longhorned Beetle. Although the Chinese have been grabbing all the Gold in the Olympics for diving they get a "did not finish" for this little critter that they sent over here in some packing crates back in 1996.
The adult beetle is 3/4" - 1 1/2" long and is shinny black with irregular white spotting on the wing covers. The antennae are overly long, black and white striped and can be up to twice the body length on males.
It's favorite place to lay it's eggs is in Maple trees but it has also been found infesting Poplar, Willow, Black Locust, Elms and Mulberries.
It has already been found as close as Clermont County, Ohio.
Once it lays its eggs in the trunk or large limbs the larvae ( cream colored, grub like, 1-2" long ) develop and eat their way around inside the tree thus destroying it as they mature.
Upon exiting the tree they leave a tell-tale 3/8" dime size, perfectly round hole as opposed to the "D-shaped hole of the Emerald Ash Borer.
Trees will exhibit symptoms similar to other types of infestations such as yellowing of leaves and branch dieback. More specific things to look for
are bleeding wounds in the trunk or large limbs, the 3/8" perfectly round exit holes and sawdust on the ground near these holes.
If you suspect that you have this nasty not-so-little bug it is imperative that you contact either myself, the local Extension Office, or Purdue University.
So, while you are out "slow soaking" your trees (as I am sure you will be...hmmm ) take a few extra seconds to inspect them for not only this guy but for any other possible insect or disease problems that may be going on. Just like us, if you catch a problem early enough a favorable treatment can be achieved at a far less expense.
Most importantly, once the ALB infests a tree there is no known cure. It can only be prevented from future infestations in other trees so take the time to check!
