Abstract: Identifying alien species is important to ensure the early detection of biological invasions and survey shifts in species distributions in the context of global change. Here, we report on three alien bark and ambrosia beetles newly detected in Switzerland: Cyclorhipidion distinguendum (Eggers, 1930), C. pelliculosum (Eichhoff, 1878), and Hypothenemus eruditus (Westwood, 1834). These species were recorded for the first time during a comprehensive survey of saproxylic beetles accross major forest types and along an altitudinal gradient during the entire growing season in the southern Alps, in the canton of Ticino. Their local abundance and number of occurrences accross different lowland forest habitats, including alluvial forests of national importance, indicates that all three species are already naturalized. Given their polyphagy, it is likely that all three species will become more extensively distributed across Switzerland, with a yet unknown environmental impact.

Tracking the spread of the northern bark beetle (Ips duplicatus [Sahlb.]) in Europe and first records from Switzerland and Liechtenstein https://alpineentomology.pensoft.net/article/53808/ Alpine Entomology 4: 179-184

DOI: 10.3897/alpento.4.53808

Abstract: The northern bark beetle (Ips duplicatus), in Europe originally restricted to northern countries, expanded its distribution range to eastern Europe in the 20th century and is now causing considerable damage in spruce forests. In the past decades its presence has been confirmed in several Central European countries. By means of pheromone traps and visual inspection of infested logs, in this study we demonstrate that I. duplicatus is also present in the Rhine valley in Switzerland and Liechtenstein. Breeding galleries with beetles and exit holes in an infested spruce log indicate that the trapped beetles had successfully developed in a local stand nearby. An inquiry addressed to European entomologists was carried out to obtain information and references concerning the year of the first record or mention of I. duplicatus in their respective countries. This information substantiated the expansion of its historical range to the southeast in the middle of the last century and clearly showed recent movement westward, with Switzerland and Germany currently the westernmost countries where this species occurs. This recent range expansion is likely attributed to the transport of infested timber. The economic significance of this expanding bark beetle species is discussed in view of its co-occurrence with the notorious pest species I. typographus.

Annotated checklist of Scolytinae and Platypodinae (Coleoptera, Curculionidae) of Switzerland https://alpineentomology.pensoft.net/article/50440/ Alpine Entomology 4: 81-97

DOI: 10.3897/alpento.4.50440

Authors: Andreas Sanchez, Yannick Chittaro, Christoph Germann, Milos Knížek

Abstract: An updated checklist of the species belonging to the subfamilies Scolytinae and Platypodinae in Switzerland is presented and briefly discussed. A total of 113 species is confirmed. This checklist is based on 42836 occurrences obtained from the identification of specimens held in museum and private collections, as well as on records taken from the literature. Fifteen species recorded from Switzerland in the past are excluded from this list, for reasons of insufficient documentation.
