Info

Other species of AgrilusFollowing are 20 species of Agrilus that are common in eastern andmidwestern North America, with a few from the southwestern U.S. Many ofthese species have already been collected on the various types of traps beingused for monitoring EAB. Only one other species of Agrilus, A. subcinctus, haspreviously been recorded as attacking ash (Fraxinus spp.) in North America. Itis a very small species that most likely only attacks small dead twigs and isdistinctly different in appearance from EAB. While other native species ofAgrilus have not been recorded as attacking living or dead ash, for somespecies the hosts are poorly known or unknown. It is also possible that manyother Agrilus species might be found incidentally resting on ash foliage ortrunks, or emerging from undetermined species of dead trees, logs andfirewood that might be monitored for EAB. In the following pages, some ofthese additional Agrilus species are compared to EAB, with some simplefeatures highlighted that can be used to distinguish them from EAB. Many ofthese Agrilus species are usually considerably smaller than EAB and should bedistinguishable on size alone. Those species that fall within the size range ofEAB can usually be distinguished on coloration differences.
