Egg mass densities up to 1.2 masses per 10 cm2 (equivalent to ~\u20091.9 eggs per cm2) were observed on trunks, branches, and exposed roots of dying <em>C. laevigata<\/em> trees in our study area, with an average of 16 eggs per mass. Fungi isolated from discolored sapwood around larval galleries did not cause defoliation, dieback, or mortality of sugarberry in inoculation trials.<br \/>\n<strong>Conclusion<\/strong> Our findings suggest that <em>A. macer<\/em> is a secondary pest on sugarberry and does not transmit harmful fungal pathogens.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nAgrilus, Eggs, Egg masses, Fungal isolation, Oviposition, Saproxylic<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-018-0794-7'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nPoole, E.M., Ulyshen, M.D., Horn, S. et al.
