Abstract

Recentni vremenski ekstremi na području Gorskog kotara rezultirali su naglim povećanjem populacija smrekovih potkornjaka. Posljedično, na području NP Risnjak 2017. godine započet je feromonski monitoring smrekovih potkornjaka (Ips typographus, Pityogenes chalcographus). Uz smrekove potkornjake u sklopu ovog istraživanja analizira se i neciljana fauna potkornjaka i fauna saproksilnih kukaca. Nakon stanke 2022. godine, monitoring je nastavljen u 2023. godini. Prikupljeni ulovi Sažetak iz 2023. godine dostavljeni su na Fakultet šumarstva i drvne tehnologije Sveučilišta u Zagrebu gdje je obavljena njihova analiza, te su izdvojene značajne vrste potkornjaka i saproksilnih kornjaša. Značajnije vrste potkornjaka i saproksilnih kornjaša su determinirane, preparirane i fotografirane digitalnom kamerom. U radu se nalazi prikaz obrađenih ulova feromonskih klopki iz 2023. godine, usporedba s rezultatima prethodnog razdoblja monitoringa, te prikaz najznačajnijih zabilježenih vrsta potkornjaka i saproksilnih kornjaša na području Nacionalnog parka.

Abstract (english)

As a result of recent weather extremes, populations of spruce bark beetles in the area of Gorski kotar suddenly increased. Consequently, in year 2017., “Risnjak National Park” started pheromone monitoring of spruce bark beetles (Ips typographus, Pityogenes chalcographus). In addition to spruce bark beetles, the non-target fauna of bark beetles and the fauna of saproxylic Coleoptera are also analyzed as part of this research. After a pause in 2022, monitoring continued in 2023. The field catches from 2023 were transported to the Faculty of Forestry and Wood Technology of the University of Zagreb, where they were analyzed, and species of bark beetles and saproxylic beetles were separated. More significant species of bark beetles and saproxylic beetles were identified, prepared and photographed with a digital camera. The paper contains a presentation of processed catches of pheromone traps from 2023, a comparison with the results of the previous monitoring period, and a presentation of the most significant recorded species of bark beetles and saproxylic beetles in the area of the National Park.
