  • A cost-benefit analysis of different traps for monitoring European spruce bark beetle (Ips typographus) [Elektronski vir] = Eine Kosten-Nutzen-Analyse verschiedener Fallen zur Überwachung des Buchdruckers (Ips typographus)

    In most European countries, traps play an important role in Ips typographus monitoring, early warning system for predicting future outbreaks and for decision making which approach is best to repair ... the damage. However, to make a good monitoring system, the most effective trap type should be used. We investigated the effectiveness of traps in catching I. typographus, their selectivity towards bycatch and towards 3 selected predators (Nemosoma elongatum, Thanasimus femoralis and Thanasimus formicarius), and the cost of using 5 different types of traps: single slot, double slot, triple slot, cross-vane and funnel traps. We investigated the difference between alternative traps (single slot, cross-vane and funnel traps) and separately between different types of slot traps (single, double and triple slot traps). We also tested whether we could sense the difference in I. typographus abundance in the locations where the natural disturbance happened in the same year as the experiment took place (tested location), compared to the undisturbed locations (control location). Altogether, we used 50 traps, where every trap type had five repetitions per treatment (undisturbed/disturbed area) and was baited with the pheromone IT Ecolure Extra®. We collected the catch from mid-April until the end of September 2020. We found that the single slot, cross-vane and funnel traps did not differ in their effectiveness and selectivity towards bycatch. The most affordable trap type is the funnel trap, followed by the cross-vane and slot traps. The results for all slot traps showed that the catch of I. typographus increases from single, through double to triple slot traps. The same pattern was to some extent observed in the bycatch and selected predators. While the number of caught I. typographus, almost doubled form single to triple slot trap, the trap expenses tripled. Among the alternative traps, the highest score in the index of effectiveness was obtained by the single slot trap. Among all three slot traps, the triple slot trap had the highest score in the index of effectiveness, closely followed by the single slot trap. Even though the cost of traps is lower compared to the cost of labour, it can still play an important role when deciding which trap type is the best choice for monitoring, risk reduction measure or research.
