“No walnut twig-boring beetles yet,” MNR.

August 6, 2013

For two summers MNR technicians have maintained an insect trap amid the black walnut trees on our property. The task was to locate examples of the walnut twig-boring beetle, a known vector for the thousand cankers disease which is currently devastating black walnut stands in the American South.

I just spoke to the technician. She told me that they soon plan to remove the trap because they haven’t found any of the dreaded critter. There are lots of butternut twig-boring beetles, but no walnut.

Needless to say I liked this news.
