20.500.12556/DiRROS-16908 First record of the northern spruce bark beetle, Ips duplicatus (Sahlberg, 1836), in Slovenia The northern spruce bark beetle, Ips duplicatus (Sahlberg), has invaded Central Europe in the past century and continues to spread southwards and westwards. It has caused damage in some parts of Europe in recent decades and poses a serious threat to spruce forests across the continent. From 2018 to 2021, we conducted intensive monitoring to determine the status of I. duplicatus in Slovenia. We used different types of traps and pheromone lures that attract I. duplicatus beetles and took bark samples from bark beetle-infested trees. Of the 26 traps used during the four years of monitoring, I. duplicatus was found in 16 traps in the central part of Slovenia in 2020. Adult beetles were caught in traps containing both I. typographus and I. duplicatus lures. The identity of this species was confirmed using morphological keys and molecular methods. One to five I. duplicatus beetles were found per trap, totaling 25 specimens. However, we did not confirm any I. duplicatus in samples taken from trees in 2021. We conclude that I. duplicatus is present in Slovenia, but our results suggest that the species is only present locally and that the population is small. biological invasions forest pests temperate forests conifers damage forest pest monitoring confirmation biološki vdori gozdni škodljivci zmerni gozdovi iglavci poškodbe monitoring gozdnih škodljivcev potrditev true false true Angleški jezik Slovenski jezik Neznano 2023-09-05 13:26:04 2023-09-05 13:26:05 2023-09-06 03:35:35 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 5. 9. 2023; str. 699-710 iss. 3 Vol. 12 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-01-01 630*4 2242-1300 10.3391/bir.2023.12.3.07 163326979 RAZ_Kavcic_Andreja_2023.pdf RAZ_Kavcic_Andreja_2023.pdf 1 VoR 97E4AA2B5DEBAF334801F780323E0F86 7a9db42340914fdd7c02ce5d0d6fea9fe8e453954bf177e66b4113e500ccb001 95700e8f-4bce-11ee-8cc8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22982 https://www.reabic.net/journals/bir/2023/3/BIR_2023_Kavcic_etal.pdf 0 c87bda40-4bce-11ee-8cc8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22983 Gozdarski inštitut Slovenije 0 0 0
