The place of different sampling methods
Absolute methods (simple, easier to correlate)
Relative methods (at low population densities, less labourintensive, often closer to every-day practice)
A combination of different methods is optimal
A relative method…
… trapping with lures

CLICK BEETLE AND WIREWORM MONITORING
• PHEROMONE TRAPS pest species occure inEUROPE• ONE inspection plus maintanance!!• 2-3 pest species/site
• Wireworms could be trapped in areas of high pheromone trap catches
•Preliminary tresholdsare available
