Our previous studies showed that adult emerald ash borer (EAB) females were more likely to oviposit on girdled trees than on wounded or healthy trees. Emerald ash borer programs in Michigan, Ohio and Indiana currently use girdled trap trees to detect, monitor and survey EAB populations. Little is known, however, about the kind and extent of tree stress that is most attractive to ovipositing EAB and how to efficiently trap beetles. We monitored adult EAB capture on healthy ash trees, trees stressed by standard girdling, herbicide treatment, or exposure to the stress elicitor methyl jasmonate during the summer. Number of beetles captured was compared among stress treatments and among sticky band traps placed on tree trunks at 1.2 and 3 m high, and purple panel traps suspended in the mid to upper canopy of trees. Trees were debarked in autumn to assess density of EAB larvae in relation to stress treatment and tree height.
