Info

emerald ash borer (continued)EAB was accidentally introduced into southeastern Michigansometime in the 1990’s in wood packing material imported fromeastern Asia. It wasn’t until 2002 that EAB was first recognized asbeing the source of ash tree deaths and its identity confirmed, bywhich time it had apparently become well established. Since then,EAB has been found in many parts of Michigan and most nearbystates and Canada. The beetles are easily transported in dead ashlogs and firewood, and despite quarantines on wood movement, thismethod of dispersal seems partly or mostly responsible for theirrapid spread. It is possible EAB might eventually spread to anywherein North America where suitable ash hosts are found. Research isbeing conducted to find effective chemical and biological controlmethods, but even then, it is unlikely that EAB can be completelyeradicated, and it will likely continue invading some other parts ofNorth America. Go to http//:www.emeraldashborer.info for currentdistributions and other up-to-date information on the EAB.
Distribution of <strong>Ash</strong> (Fraxinus spp.)As many as 21 species of ash(Fraxinus spp.) are distributedthroughout much of the UnitedStates. EAB is known to feed onthe 4 major ash species found inthe northeast U.S., but whether itwill feed on other ash species orbe able to adapt to other areas inthe U.S. is not well known at thistime. However, this guide doesinclude some beetle species fromthe western and southeasternU.S. for comparison purposes incase it eventually invades thoseareas.Approximate distribution of Fraxinusspecies in North America
