2. Influence of felling residue management on bark beetles and other insect diversityMaarten De Groot, Luka Capuder, I. G. Farah Kootstra, Martin Križaj, Marija Kolšek, Mitja Ferlan, Tine Hauptman, 2025, original scientific article Abstract: Bark beetle outbreaks have caused large-scale tree mortality and damage in recent decades, primarily following an increase in largescale forest disturbances induced by climate change. After tree logging operations, leftover branches are traditionally piled to make the potential brood material less suitable for bark beetles, thereby lowering the risk of subsequent attacks on surrounding trees. On the other hand, the residues could prove valuable to biodiversity by supplementing important habitat, given the apparent decline in deadwood in European forests and its associated saproxylic fauna. Our aim was to identify the most successful method of logging residue management for both bark beetle management and biodiversity. We focussed on Norway spruce felling residues, their associated bark beetle pests and saproxylic insect orders, beetle families, and Cerambycidae species.We prepared four treatments: (i) logging residues in piles, (ii) scattered logging residues, (iii) logging residues removed, and (iv) a control plot with no felling activity. Five plots per treatment were established at each site. In total, three sites were selected: one at a high elevation and two at lower elevations in different parts of Slovenia. The catch was counted to the order level, the attracted beetles were identified to the family level, and Cerambycidae and Scolytinae to the species level. We found that the treatments with residues attracted the highest diversity of insect orders and the most beetles across different families, including Cerambycidae. Furthermore, we found that the species composition differed between control and residue treatments, although no difference was observed in species richness. More bark beetles and a higher number of bark beetle species were attracted to both piled and scattered residues. Thick branches were more frequently attacked in scattered residues. There was no difference in the number of attacked trees (within a plot) one month after treatment. Hence, leaving logging residues in the forest could represent an interesting compromise between pest management and biodiversity conservation. Conf licting aims, such as increasing biodiversity or controlling bark beetles, should be carefully considered in the management decisions.

3. First record of the non-native Cnestus mutilatus (Blandford) and further findings of other Xyleborini (Curculionidae, Scolytinae) recently recorded in SloveniaTine Hauptman, Luka Capuder, Zina Devetak, Maarten De Groot, Massimo Faccoli, Barbara Piškur, 2025, original scientific article Abstract: Ambrosia beetles of the subfamily Scolytinae (Coleoptera: Curculionidae) have successfully invaded many parts of the world and are increasingly being introduced to new areas, primarily through international trade. The number of non-native species recorded in Slovenia is also increasing. During the national survey of quarantine species in 2024, a new non-native scolytine beetle, Cnestus mutilatus, was recorded for the first time in Slovenia. Two specimens were trapped at Radmožanci, a location in northeastern Slovenia. New data on two other species recently recorded in Slovenia, Anisandrus maiche and Xylosandrus compactus, are also presented.
