Research Project: Monitoring Tools for the Detection of Biological Control Parasitoids of the Emerald Ash Borer

Location: Crop Bioprotection Research

2011 Annual Report

1a.Objectives (from AD-416)
Investigate and develop attractants for three emerald ash borer parasitoids.

1b.Approach (from AD-416)
Collect, compare and quantify male- and female-specific volatiles. Determine the GC-EAD activity of the sex-specific compounds. Identify sex-specific compounds with biological activity. Synthesize the new compounds and formulate for behavioral testing. Determine the effects of various environmental and biological parameters on the production of sex-specific compounds. Isolate, identify, and synthesize host and tree related attractants. Wind tunnel and field tests.

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. Three species of parasitic wasp originally reared from EAB in China have been released in the U.S. as possible biological EAB control agents. We have identified the pheromone of one of these parasitic wasps. This natural attractant could be used in monitoring systems to evaluate the establishment and spread of newly released populations of EAB biocontrol agents.
