Abstract
Six trap models were compared with respect to their ability to capture European spruce bark beetles and technical details in handling and use. All trap models proved to be efficient and gave high captures of beetles during operation for one summer season (2013). Ranking the trap models in descending order of total capture of beetles gave this list: Lindgren trap, Theysohn, prototype-P, Ecotrap, BEKA, and prototype-K. However, there was much variation in trapping results between localities for all trap models, and the estimated means did in most cases not differ significantly between models. The estimated mean capture of the Lindgren trap was significantly higher than for prototype-K and BEKA, but their confidence intervals were wide and they were close to being insignificantly different. The retail price of the traps vary from about 10 € (Ecotrap) to 50-55 € (Lindgren), while prices are not available for the two prototypes, which are not in regular production. Advantages and disadvantages concerning weight, size, robustness, draining of rain water, ease of handling and mounting are commented on in the discussion, and technical details of the traps are presented in a separate appendix (6).
