7. First record of non-native Xylosandrus compactus and Anisandrus maiche (Coleoptera: Curculionidae, Scolytinae) in SloveniaTine Hauptman, Zina Devetak, Maarten De Groot, Massimo Faccoli, Barbara Piškur, 2024, original scientific article Abstract: The introduction of non-native organisms into new areas may pose major threats to natural ecosystems. Therefore, continuous and careful national surveys for the interception of invasive non-native species are necessary. During the national survey of quarantine species in 2023, two new non-native ambrosia beetles, Anisandrus maiche (Kurentzov) and Xylosandrus compactus (Eichhoff), were recorded in Slovenia. Anisandrus maiche was recorded in three locations in the eastern part of Slovenia, with a total of 386 individuals. Three individuals of Xylosandrus compactus were collected in one location near the port of Koper. We discuss the possible pathways of introduction and dispersal.

8. Diversity and pathogenicity of Botryosphaeriaceae and Phytophthora species involved in emerging diseases of Fagus sylvatica in Italy and SloveniaCarlo Bregant, Massimiliano Marcolongo, Lucio Montecchio, Nikica Ogris, Barbara Piškur, Benedetto Teodoro Linaldeddu, 2024, original scientific article Abstract: Extensive sunken and bleeding cankers, shoot blight, and root rot symptoms on European beech (Fagus sylvatica L.) trees have recently been observed in several forest ecosystems in Italy and Slovenia. Since there is little information about the aetiology of these diseases and given the high economic and ecological relevance of these formations, a study was conducted from summer to autumn 2023 in ten sites to define the occurrence, distribution and impact of the main pathogens involved. A total of 116 symptomatic samples were collected and processed. Based on colony appearance, morphological features and DNA sequence data, six species belonging to the genera Botryosphaeria, Dothiorella, Diplodia, Neofusicoccum (fungi) and Phytophthora (oomycetes) were isolated and identified. Pathogenicity tests performed on potted European beech seedlings satisfied Koch postulates and highlighted that Diplodia corticola, Neofusicoccum parvum and Phytophthora plurivora are the main agents involved in the extensive decline affecting European beech ecosystems in Italy and Slovenia.
Keywords: Diplodia corticola, beech decline, invasive species, emerging diseases, co-infections
