The emerald ash borer (EAB), Agrilus planipennis Fairmaire (Buprestidae), a native of Asia, was discovered in the USA and Canada in 2002. This serious pest of ash trees (Fraxinus sp.) infests and quickly kills trees by mining the cambium area, disrupting the tree’s transport system. As newly infested trees do not typically show distinctive external visual symptoms there is a growing need to be able to trap adult beetles so that accurate surveying can be done. We collected bark and leaf volatiles from healthy and girdled ash trees using solid phase micro-extraction (SPME). We also prepared extracts by washing leaves in methanol and hexane. Volatile components were screened for EAB antennal activity using coupled gas chromatographic electro-antennal detection (GC-EAD). Compounds that elicited antennal responses were identified by gas chromatography (GC) and mass spectrometry (MS).
