Evaluation of semiochemicals potentially synergistic to a-pinene for trapping the larger European pine shoot beetle, Tomicus piniperda, (Col., Scolytidae)

Abstract

The pine shoot beetle, Tomicus piniperda (L.) (Col., Scolytidae) is an exotic pest of pine, Pinus, spp., in North America. It is attracted strongly to host volatiles (±)-a-pinene, (+)-3-carene, and a-terpinolene. Attraction to insectproduced compounds is less clear. Other potential attractants include trans-verbenol, myrtenol, myrtenal, nonanal and a-pinene oxide. We conducted a series of field experiments to determine if any of these compounds would increase attraction of T. piniperda to a-pinene, either individually or in various combinations. None of the individual compounds increased attraction. Although several combinations that included trans-verbenol, nonanal, myrtenol, or myrtenal increased attraction, results were variable between experiments.
