Photo of Hiawatha National Forest personnel work together to set up a test for scale-resistance on a beech tree as part of a training workshop run by FS researchers.  Genetic markers identified in recent studies may allow resistant trees to be selected without using the type of testing shown here, which can take up to a year.

Photo of Photo taken with a 40 X dissecting microscope at the Delaware, Ohio, research facility eight weeks after EAB egg hatch in September 2014.  In the center of the light colored tissue is a small dark, oblong-shaped emeral ash borer larva that failed to survive in the ash host tree, a possible indication that the tree may be resistant to the beetle.
