20.500.12556/DiRROS-13687 Estimating the most effective and economical pheromone for monitoring the European spruce bark beetle In recent decades, there have been an increasing number of outbreaks of Ips typographus in Europe. A large amount of sanitary felling has taken place, with significant economic and ecological consequences. In order to anticipate such large%scale outbreaks, an effective monitoring system should be set up. One important aspect of monitoring is deciding which pheromone to use. Therefore, we decided to test five different commercially available pheromone lures under different disturbance conditions: Pheroprax%, IT Ecolure Extra%, Ipstyp%, Ipsowit% and Typosan%. We investigated the ability of the pheromones to distinguish between disturbed and undisturbed locations, their cost%efficiency ratio, and side effects such as bycatch abundance and composition. We set 50 traps in two areas with sites that were disturbed and undisturbed by windstorms. We collected the catch from traps every 1%2 weeks from the end of March until the end of September in 2019. We found that IT Ecolure Extra%, Ipsowit% and % Pheroprax% caught the most I. typographus and best showed changes in the trap catch of I. typographus throughout the whole season. There was a low amount of bycatch (<6% of the total catch) and a low number of predators (a few specimens), but some groups seem to prefer certain pheromones. The cost of the pheromones increased with their effectiveness. However, pheromone costs are low relative to the personnel costs involved in setting traps and collecting the catch. Based on all of the gathered data, we created an index which helps to assess the cost%efficiency of the five chosen commercially available pheromones. We also present guidelines on how to make such an index to assist other researchers in choosing the right pheromone for monitoring populations of I. typographus or other bark beetle species. bark beetles cost-efficiency Ips typographus monitoring pheromones Picea abies monitoring podlubniki stroški Ips typographus Picea abies true false true Angleški jezik Ni določen Neznano 2021-01-21 08:54:03 2021-01-21 08:54:05 2022-08-19 03:36:04 0000-00-00 00:00:00 2021 0 0 Nasl. iz nasl. zaslona; Opis vira z dne 15. 1. 2021; str. 312-325 iss. 4 Vol. 145 2021 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 630*4 1439-0418 10.1111/jen.12853 47183619 519845657 RAZ_Sramel_Nina_i2021.pdf RAZ_Sramel_Nina_i2021.pdf 1 13E1D00971687B5B2C9405D2DACE2170 966548ae0afe6d1127317b58e27342ae907744d3f207118a20dfff782238ff9f bad9b5c1-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=18378 https://onlinelibrary.wiley.com/doi/10.1111/jen.12853 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=16710 Gozdarski inštitut Slovenije 0 0 0
