    Description

    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.
