Abstract

Host selection by the hickory timber beetle, Xyleborus celsus (Coleoptera: Scolytidae), was studied using axe-girdled, herbicide-treated, and healthy black hickories, Carya texana (Buckley), 10–25 cm D.B.H. Many more beetles were caught on sticky traps placed on treated trees than on sticky trees placed on untreated trees. Traps on treated trees 17 cm D.B.H. or larger caught more beetles than traps on trees 10–15 cm D.B.H. The interval between treatment and initial beetle attack varied with season. Beetles were not attracted to window flight traps baited with 118 ml of 95% ethanol.
