Abstract Verbenone andtrans-verbenol were investigated as candidate interruptants for use as tree protectants. Verbenone andtrans-verbenol, pheromones released byDendroctonus brevicomis during host colonization, reduced the trap catch ofD. brevicomis near sources of the attractant composed ofexo-brevicomm, frontalin, and myrcene. Catch reduction at some trap positions was greater at a high release rate than at a low release rate oftrans-verbenol alone and of the combination of verbenone plustrans-verbenol. Verbenone also reduced catches at traps baited with attractive bolts from trees under attack byD. brevicomis. Attempts to use verbenone to protect living trees fromD. brevicomis attack were inconclusive.
