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

Location: Crop Bioprotection Research

2011 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 (EAB) is an invasive beetle pest from Asia that is causing widespread mortality of ash trees in the U.S. and Canada. National surveys performed by Federal and State agencies are to determine the presence of EAB in forests, woodlots, and urban areas. These surveys rely on traps baited with attractants that are placed in still healthy ash trees. The current attractants are based on attractive compounds released by stressed ash trees. Since these attractants are not commercially available, they will have to be synthesized. We have identified the stereochemistry of one of the major EAB host attractants. This result is important so that the correct chemical is made for the bulk synthesis of EAB host attractants. Furthermore, we have confirmed the behavioral function of the earlier identified EAB female-produced sex pheromone in field experiments in the U.S. and Canada. This pheromone could be used to increase the effectiveness of the attractants already in use for the monitoring of EAB.
