The emerald ash borer, Agrilus planipennis (Coleoptera: Buprestidae), is a serious invasive pest of North American ash (Fraxinus spp.) that has caused devastating mortality since it was first identified in North America in 2002. In 2012, we conducted field trapping assays that tested the efficacy of purple prism and fluon-coated green multifunnel (Lindgren funnel) traps. Traps were baited with combinations of several lures that were previously shown to be attractive to A. planipennis: manuka oil--a sesquiterpene-rish oil, (3Z)-hexenol--a green leaf volatile, or (3Z)-dodecen-12-olide [= (3Z)-lactone], a sex pheromone. Eighty-nine blocks (trap lines) were tested throughout nine states along the outer edges of the currently known A. plannipennis infestation in North America. Trap catche was highest on fluon-coated green multifunnel traps, and trap detections at sites with low A. plannipennis population density ranged from 72 to 76% for all trap and lure types tested. (3Z)-hexenol and (3Z)-lactone baited traps functioned as well as (3Z)-hexenol and manuka oil-baited traps. Independent of the lure used, detection rates on green fluon-coated multifunnel traps were comparable with glued purple prism traps in areas with low A. plannipennis population densities.
Plain Language Summary
This was the result of an international collaborative project between CFS, Canada and USDA, USA comparing detection tools for the emerald ash borer. The CFS technology using the EAB pheromone, (3Z)-dodecen-12-olide, together with an ash volatile, (3Z)-hexenol, was found to be comparable to the product developed in the USA using other ash volatiles. The CFS product is now commercialized in NB.
