Additional traps have just gone up...

I was back in Tennessee this week installing additional traps for walnut twig beetle.  Our funnel traps haven't yielded any beetles thus far this summer, so we are baiting fresh walnut bolts with lures in hopes of enticing the critters.  Along with lures, we attached sticky cards on each bolt so we can get an idea of just what insects we are attracting.

We are throwing everything we can in suspect trees, hoping to pick up on some walnut twig beetle activity.  Last summer, we observed a real spike in beetle activity during the month of August.  We are hoping to see the same this year, if not, then we will be re-thinking our planned experiments for September and October.
