Beware the Asian Longhorned Beetle

This is truly the stuff horror films and nightmares are made of:  Last week the RI Department of Environmental Management released a report that the presence of Asian Longhorned Beetle (ALB) larva was suspected in a load of firewood delivered to a home in Cranston, RI.  The wood came from a property in Worcester, MA known to be infested.  Even though Cranston is all the way across the Bay from Blithewold, this hits just a little too close to home!  The beetles themselves don’t range far from their chosen host tree, but the scary thing is, we do and it has hitchhiked on green wood from China to New York to New Jersey to Illinois to Massachusetts (not necessarily in that order) and now maybe even to little Rhody.

Remember when the USDA hired US Forest Service smoke jumpers to spot beetles at the tippy tops of Central Park’s treasured American Elms?  That’s when I first became very aware of just how tragic and deadly an infestation would be.  ALB feed on hardwoods – maple, horse chestnut, willow, and elm to name just a few of their favorites – and will kill their host and move on to the next tastiest choice.  Infested trees have to be cut down, chipped immediately and even burned in order to stop the beetles from spreading.  Adjacent hardwoods are also often removed and/or treated with pesticides and the neighborhood put under vigilant surveillance for signs of further invasion.  The good news is, eradication is possible.  Illinois has declared victory over ALB after a ten year push to rid it from several Chicago neighborhoods.

It’s very important that you not try to handle an infestation on your own.  And it cannot be ignored without truly frightening consequences.

I absolutely can’t imagine life without the trees that I take for granted every day.  Actually,I shouldn’t say that I take them for granted – this time of year at least, I’m completely riveted by them!

One thought on “Beware the Asian Longhorned Beetle

  1. Kris: Kudos to you on spreading the news of this unnatural disaster in waiting. The more who are aware of the impending problem, the better the chances of eradication before it takes hold. I’m keeping my eyes peeled.

    That’s great, Layanee and I’m sure you’ll pass it on! And if kudos are being handed out, a bunch should go to Dan and Julie (Murphy not Morris!) for speedily sending an email alert to Blithewold members.
