What's that triangular purple box hanging in trees?

It's all about EAB, or Emerald Ash Borer (Agrilus planipennis), a ruthless insect invader from eastern Russia, northern China, Japan, and Korea.  How did it get here?  It's not clearly known, but it is likely that it came in ash wood used for stabilizing cargo in ships or for crating consumer products. 


Recently, an EAB trap was put in an ash tree across the street from our offices at the Old Port park.

EAB is a wood boring beetle first found in SE Michigan nine years ago.  Ever since, it has been detected in southern Prince George's County, Maryland; Indiana, Illinois, Pennsylvania, Virginia, West Virginia, and other states.  EAB is a serious pest to the ash trees as the adult beetles feed on the tree's foliage and the larvae, the most harmful life stage, feed on the inner bark of the trees creating S-shaped tunnels that damage the vascular tissues under the bark.  Of course the ash trees then die. 

The purple boxes you see in many trees throughout the state are traps set in ash trees to attract and catch the beetles.  These traps are set by the Maryland Department of Agriculture (MDA) as part of a national survey for the emerald ash borer.  People should not be worried about these traps and should actually not disturb them since this is part of a major effort to detect this pest and to save our ash trees!  Read more at the EAB website.

What is inside the box? Anyone know? It would be nice to make a couple myself and hang them in my woods. There's a lot of ash around here and having more traps might be a good idea in this case. Thanks.

Thanks

I see numerous purple boxes in the upper poconos of PA. I always wondered what they were for.Thnks for clearing that up.

Thank you for clearing up

Thank you for clearing up this for me. I noticed a couple purple boxes in the trees on my drive in Ct./NY. This was very helpful....

Ah...the mystery solved.Β  I

Ah...the mystery solved.  I just started seeing them along the eastern part of the PA Turnpike and was wondering.  Thanks.

Thank you for this

Thank you for this information.

I've seen a number of these

I've seen a number of these traps set up here in Western Massachusetts. I first read about the EAB infestation early last year, so I had a guess that these were to combat the beetles. I'll be sure to let my friends and coworkers know what exactly they are. Thanks for your efforts to stop the EAB!

Correction:

Whoops, my mistake. It was the Asian Longhorn beetle infestation that I read about early in early 2010. That infestation still seems to be spreading like wildfire. Are there any plans of setting up similar traps to stop the Longhorns?

Purple Boxes

Thanks! This was a great debate. We have one at the entrance of our subdivision. We live in Central Kentucky.

ash borer

ABOUT 10 OR MORE YEARS AGO WE TOOK AN WHITE ASH TREE DOWN BECAUSE IT WAS BEING EATEN BY SOMETHING. I NOTICED THAT THE STUMP THAT IS LEFT HAS HOLES BEING DUG OUT OF IT.THE TRUNK IS ALMOST GONE NOW. I THINK THAT IT WAS ORIGINALLY INFESTED WITH THIS ASH BOAR. SHOULD I HAVE A PURPLE BOX PUT UP SO IT DOESN'T SPREAD? WHERE DO I GET ONE? THANKS JANICE

RE: ash borer

Hey Janice,

 

I recommend contacting the folks at the Maryland Department of Agriculture (http://www.mda.state.md.us/about_mda/staff_dir/index.php) --or if you don't live in MD, any state agency related to forestry, agriculture or natural resources-- for more information about getting a purple box installed on your property, because I'm pretty sure that is not something you can buy at a store.

 

Hope this helps.

 

Best,
