New Lure for the Larger Pine Shoot Beetle, Tomicus piniperda — Attractant/Trap Design Combinations Tested in North America and Europe

An optimized, patented lure for the larger pine shoot beetle, Tomicus piniperda has been developed and tested in the United States, Poland, and Croatia. Seven different beetle attractants were tested: α - pinene, α -pinene oxide, ethanol, nonanal, myrtenal, myrtenol, and trans-verbenol. α -pinene was tested alone or in combination with two or more of the remaining compounds. Attraction of all candidate lures was compared to attraction of Tomodor, a Polish commercial lure for T. piniperda, using the Intercept™ Panel Trap (PT). A lure containing α -pinene, α -pinene oxide, nonanal, myrtenal, myrtenol, and trans-verbenol was used to compare trap captures in Intercept PT with 12- unit multi-funnel traps in USA, Theyson trap in Croatia, and IBL-3 trap in Poland. This study demonstrated that at least a quaternary semiochemical combination, including α -pinene, nonanal, trans-verbenol, and myrtenol is required to assure maximum trap captures. The best IPM Tech lure was significantly more attractive than Tomodor when tested in Poland and Croatia. Catches of T. piniperda in the Intercept PT were significantly higher than in the IBL-3 trap or Theyson trap.
