Info

The main purpose of this guide is to assist with sight identification ofadult specimens that have been field collected or reared. It will besomewhat easier to verify the identity of beetles reared from knownhosts, however host data is not necessary to use this simple guide.Many trapping methods for EAB utilize Tanglefoot®, Pest-Stick® orsome other kind of sticky material. To be able to properly identifyspecimens, all residues of this sticky material must be removed with asuitable cleaning agent. Soaking beetles in 95% ethanol will dissolveTanglefoot, and Histoclear® will dissolve Pest-Stick. It may takeseveral days of soaking and frequent transfers to clean solvent toremove all traces of the sticky material. In addition, specimens inalcohol usually do not appear their true color or show setae and setalpatterns while wet. Ideally, specimens should be cleaned and allowedto air dry. Specimens mounted on pins or points will usually be mucheasier to manipulate under a dissecting microscope, which is usuallyneeded for best examination of these small beetles. The bright lightingtypically used with microscopy will best reflect the coloration of thesebeetles for comparison to the pictures used in the guide.
Note the similarity in color among the beetles in the photos to the left that wereremoved from sticky traps and pinned without any cleaning. The photos to theright are the same beetles after cleaning for only a few seconds with hexaneused as a solvent. While still not perfectly clean, sufficient color and patternsnow are evident to allow these to be identified to species.AgrilusanxiusAgrilusbilineatusAgriluscyanescens
