Sawyer beetles (Monochamus spp.: Cerambycidae) are the most important vectors of Bursaphelenchus xylophilus, the Pine wood nematode (PWN), which can cause the death of Pines of all ages in only one vegetation period. In the countries of EU the PWN is listed on the A1 list of quarantine pests. In the year 2014, we tested the impact of two attractants, Galloprotect 2DR and Galloprotect PackR, on the catch of Monochamus species. On the locations Snežnik and Trnovo (Slovenia) we choose the plots with a radius of 70 meters, in the forest stands of Norway spruce (Picea abies) and silver fir (Abies alba) and with three levels of cutting (100%, 50% and 0%). Cross vane funnel traps (Witasek) with wet collecting cups were put in the middle of each plot. In total 276 specimen of sawyer beetles were collected. Three different species were identified: Monochamus sartor (127 specimens), M. sutor (104 specimens) and M. galloprovincialis (45 specimens). All three species were more frequent on the plots with Norway spruce. On two plots with Norway spruce, the catch on Galloprotect PackR was significantly higher. However, on one plot with silver fir, the significantly higher catch was detected on Galloprotect 2DR. The highest catch was established on the plots with 100% cutting. The additional catch of predatory coleoptera species from Cleridae and Troggositidae families was also detected.
