Abstract: | 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 (±)- α -pinene, (+)-3-carene, and α -terpinolene. Attraction to insect-produced compounds is less clear. Other potential attractants include trans -verbenol, myrtenol, myrtenal, nonanal and α -pinene oxide. We conducted a series of field experiments to determine if any of these compounds would increase attraction of T. piniperda to α -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. |
