Research Project: ISOLATION AND IDENTIFICATION OF SEMIOCHEMICALS IN SUPPORT OF THE DETECTION AND BIOCONTROL OF EMERALD ASH BORER, AGRILUS PLANIPENNIS
2010 Annual Report


1a.Objectives (from AD-416)
Identify semiochemicals from host plants, natural enemies and/or conspecifics that can be used as tools in the management of the invasive emerald ash borer.


1b.Approach (from AD-416)
Laboratory and field research will be done to identify, isolate, synthesize, and test antennally active semiochemicals of emerald ash borer.


3.Progress Report

The emerald ash borer (Agrilus planipennis, "EAB") is a severe invasive pest from Asia that threatens the ash tree (Fraxinus spp.) populations in North America. Work continued on attractants for the detection of EAB focusing on host plant related compounds and a putative female produced pheromone. Female EAB antennae were found to be more sensitive to two isomers of the pheromone than male antennae, and there were no differences in activity between the natural and unnatural isomers. The isomers were synthesized in collaboration with scientists from the Canadian Forest Service; and a large-scale field experiment is underway in collaboration with APHIS and the Canadian Forest Service to evaluate the field attractivity of the two pheromone isomers. In addition, a formulation was developed for a steady release of the pheromone material lasting at least 2 weeks under field conditions.
