Different responses of Monochamus galloprovincialis and three non-target species to trap type, colour, and lubricant treatment

With the increasing threat to forests in Europe from invasive pine wood nematode (PWN) Bursaphelenchus xylophilus, effective methods are needed monitor and reduce populations of its insect vector, sawyer beetle Monochamus galloprovincialis. In present study, we tested effectiveness different trap types (multiple-funnel, cross-vane, triangular), colours (black, white clear), lubricant (polytetrafluoroethylene, PTFE) treatments (different PTFE formulations timing treatment) on catches M. galloprovincialis three most commonly captured non-target species (the xylophagous Spondylis buprestoides two predators, Thanasimus formicarius T. femoralis) Poland. Of traps not treated with PTFE, black 6-funnel were trapping beetles, while cross-vane (both clear) low. Trap treatment significantly increased effectiveness, regardless type time application. The S. affected by type, those depended colour size. Both seem respond positively ethanol and/or α-pinene lure composition. had a significant effect femoralis. conclusion, for monitoring galloprovincialis, recommend dry PTFE. They less but still catching target species, their use, together lures containing no α-pinene, greatly reduces insects formicarius.
