Abstract

In 2012, we evaluated the effects of hardwood cerambycid pheromones (syn-2,3-hexanediol, 3-hydroxyhexan-2-one, and 3-hydroxyoctan-2-one) on catches of bark and woodboring beetles in ethanol-baited multiple-funnel traps in two field trials in Oregon and Washington, United States of America. Catches of Phymatodes aeneus LeConte (Coleoptera; Cerambycidae) in ethanol-baited traps increased with the addition of 3-hydroxyhexan-2-one lures or the 3,2-hydroxyketone lure blend (3-hydroxyhexan-2-one 3-hydroxyoctan-2-one). Catches of the predator Thanasimus undatulus (Say) (Coleoptera; Cleridae) in ethanol-baited traps increased with the addition of 3-hydroxyhexan-2-one lures but not syn-2,3-hexanediol lures or 3-hydroxyoctan-2-one lures. The 3,2-hydroxyketone lure blend decreased catches of the corthyline ambrosia beetle, Gnathotrichus sulcatus (LeConte) (Coleoptera; Curculionidae), but not the xyleborine ambrosia beetle, Xyleborinus saxesenii (Ratzeburg), (Coleoptera; Curculionidae). Catches of Ptilinus basalis LeConte (Coleoptera; Anobiidae) in ethanolbaited traps increased with the addition of the 3,2-hydroxyketone lure blend.
