“… Cryphalus piceae has a more southerly distribution. Until now the northernmost record was Denmark ( Justesen et al 2020 ), but it was recently collected in southern Sweden ( Lindelöw and Jonsell 2022 ). It is found in most of central and southern Europe where Picea and Abies are present.…”

“…The five native European species are not regarded as serious pests, but C. piceae , C. numidicus , and to some extent C. saltuarius have been mentioned as bark beetles able to kill weakened trees. Both C. piceae and C. numidicus have been reported as problematic pests when the population density gets high ( Toper 2002 ; Lieutier et al 2016 ; Justesen et al 2020 ). Despite this, most of the available biological data for the five species is scattered in smaller papers or older literature in several different languages often with a restricted focus.…”

Species in the genus Cryphalus are small and notoriously difficult to identify. Even among the relatively well studied European species, erroneous identifications are evident from literature and in museum collections. These misidentifications relate to the small size and similar appearance of Cryphalus species but they are also a product of insufficient diagnostic characters. This is especially unfortunate since some European species are considered pests. Based on the study of more than 1000 specimens and a thorough literature review, robust morphological and molecular evidence supporting all five hitherto recognised native species of Cryphalus in Europe is provided. A key for the reliable identification of these repetition species including new diagnostic characters recognised for the first time, including those from male genitalia, has been constructed. Each native species is provided with a detailed morphological description and their economic significance, distribution, and ecology discussed. Significant genetic variability is observed between certain clusters that should be further explored in a broader geographic context. Lastly, the need for a taxonomic revision of the genus Cryphalus for the entire Palearctic region due to the presence of many similar looking species which are often confused, thus distorting the knowledge of each species is highlighted.

“…For instance , Cryphalus asperatus is sometimes abundant in the UK while C. piceae is recorded as a nonestablished introduced species in the UK ( Duff 2016 ). Neither is usually of economic importance, but they can both have a significant economic impact and kill healthy trees under certain circumstances ( Justesen et al 2020 , Fiala and Holuša 2021 ). As another example , Tomicus piniperda is a significant pest of Scots pine ( Lieutier 2002 , Kerdelhue et al 2006 , Wainhouse and Inward 2016 ).…”

Bark-feeding and wood-boring insect pests can have significant negative impacts on conifers and wood production. The damage they cause is expected to increase in the future due to climate change and the growth of international trade. This study employed DNA barcoding of beetle juveniles (Coleoptera) sampled from standing trap trees and cut log piles at regular intervals over a 2-yr period to monitor the beetle community dynamics and associated environmental factors. Tree species was found to have a major influence on beetle communities, most strikingly at the start of early decay stages. Lower species diversity was reported from standing trap tree samples compared to log pile samples, likely due to higher residual defences in dying and recently dead trees. While the species identified from standing trap trees are more likely to be a threat to the forestry sector, the species found in the log piles are more likely to be beneficial due to their high abundance and their ability to compete with pests for breeding substrate. The analysis of beetles collected inside trees revealed additional information on ontogenetic niches and host preferences beyond that acquired solely from flight interception trap data. Our results offer insights on community composition and dynamics of bark-feeding and wood-boring insect species in Welsh conifer forests and provide resources for monitoring and management of potential pest species.

“…In Europe and Asia, Cryphalus piceae infests various species of Abies, Pinus, Picea, and Larix (Jankowiak and Kolarik 2010). This bark beetle predominantly affects stressed trees (Michalski and Mazur 1999), but can also attack healthy ones (Justesen et al 2020). Previously, several fungal species were isolated from Cr.…”

Cryphalus piceae attacks various economically important conifers. Similar to other bark beetles, Cr. piceae plays a role as a vector for an assortment of fungi and nematodes. Previously, several ophiostomatoid fungi were isolated from Cr. piceae in Poland and Japan. In the present study, we explored the diversity of ophiostomatoid fungi associated with Cr. piceae infesting pines in the Shandong Province of China. We isolated ophiostomatoid fungi from both galleries and beetles collected from our study sites. These fungal isolates were identified using both molecular and morphological data. In this study, we recovered 175 isolates of ophiostomatoid fungi representing seven species. Ophiostoma ips was the most frequently isolated species. Molecular and morphological data indicated that five ophiostomatoid fungal species recovered were previously undescribed. Thus, we proposed these five novel species as Ceratocystiopsis yantaiensis, C. weihaiensis, Graphilbum translucens, Gr. niveum, and Sporothrix villosa. These new ophiostomatoid fungi add to the increasing number of fungi known from China, and this evidence suggests that numerous novel taxa are awaiting discovery in other forests of China.
