The adult beetles nibble on ash <br />foliage but cause little damage. The larvae (the immature stage) feed on the inner bark of ash <br />trees, disrupting the tree's ability to transport water and nutri ts. Emerald ash borer probably <br />arrived in the United States on solid wood packing materi � ''ed in cargo ships or airplanes <br />originating in its native Asia.

How these trees became infested is <br />not known, though it is worth noting that the trees are only a half mile from interstate highway <br />35W and in other states the principal spread of EAB has been along travel corridors. <br />Emerald Ash Borer Management Plan - City of Arden Hills Page 1 <br />
