Summary: This study reports the first North American record of the bark beetle Ernoporus parvulus collected from Pinellas County, Florida, USA. Two previously described Caribbean species, Ernoporus minutus and E. exquisitus, were found to be synonymous. These beetles are likely overlooked exotics from Africa.

Summary: Species in the genus Cryphalus are often difficult to identify in Europe, with frequent misidentifications due to their small size, similar appearance, and lack of diagnostic characters. This study provides robust morphological and molecular evidence supporting the recognized native species of Cryphalus in Europe, based on the examination of over 1000 specimens and a thorough literature review. A key for reliable identification, including new diagnostic characters, has been constructed. The study also highlights the need for taxonomic revision of the genus Cryphalus in the entire Palearctic region.

Summary: The Malagasy bark beetle genus Pseudomicracis has been revised based on molecular and morphological studies. Six new species have been described from Madagascar. The diagnosis of the type species was fixed using an auxiliary species. New distributional and host records are given for some species, and a molecular phylogenetic analysis was conducted. A key and photographs of all Malagasy species are provided.

Summary: This study used comparative proteomics to investigate the digestion and detoxification processes in male and female I. typographus during their callow and sclerotized stages. The differential abundance proteins identified were mainly involved in binding, catalytic activity, anatomical activity, hydrolase activity, metabolic process, and carbohydrate metabolism, which are crucial for growth, digestion, detoxification, and signalling in the beetles. Furthermore, different protein regulation patterns were observed in metabolic and functional processes between the developmental stages of I. typographus.

Summary: Research shows that the population densities of I. typographus and P. chalcographus within the Carpathian Mountains are increasing, mainly due to non-synchronized and diverse management strategies. A three-year assessment in the Apuseni Natural Park with a surface area of 75,784 hectares revealed high densities of both beetle species in managed and unmanaged forests, emphasizing the need for a synchronized management system. Climate variables such as temperature and precipitation have more significant effects on population density than management practices.

Summary: Canopy fogging was used to sample the diversity of bark and ambrosia beetles in two western Amazonian rainforest sites in Ecuador. A subset of the data analyzed in this study found high diversity of these beetles, with a total species richness estimated between 260 and 323. However, undersampling was identified as a limitation affecting the accuracy of beta diversity estimates.

Summary: The unintentional transport of insects beyond their native ranges has increased with globalization, leading to higher propagule pressure in non-native ranges. This study investigated the interceptions of European spruce bark beetle in the USA from 1914 to 2008 and found that interceptions were not related to outbreak levels in the native range, but were inversely related to annual import volume. The abundance of this beetle in invasion pathways has recently decreased, possibly due to strengthened phytosanitary protocols.

Summary: This article describes various methods for collecting and preserving bark and ambrosia beetles, including collecting tools, recording data, and step-by-step beetle extraction techniques. It also elaborates on trapping techniques, tools, attractants, and beetle preservation. The key rule for manual collecting is to separate the wood or bark from the beetle gently and systematically, instead of trying to pry the insect out. The main rule for trapping is to use attractants and traps that reflect the ecology of the targeted beetle species.

Summary: A new species of bark beetle, Scolytus jiulianshanensis, from Jiangxi, China, is distinguished from other Asian Scolytus species by the presence of a broad median tubercle on the apical margins of ventrites 3 and 4 of the male, along with the absence of ventral spines. This new species was collected from dead elm trees and a DNA barcoding sequence is provided for further identification.

Summary: Invasive populations of small spruce bark beetle Ips amitinus were first registered in the southeast of Western Siberia in 2019. The beetle caused significant damage to pine collections in a local arboretum in 2020, necessitating ongoing monitoring to protect plant species and understand the impact of the invasion.

Summary: This study investigated the distribution, phenology, and habitat preferences of Dryocoetes himalayensis in the Czech Republic. The species was found to be relatively widespread in warmer lowland regions, with a peak emergence in June. It showed a preference for attacking larger trees and common walnut trees with decreased vitality. These findings suggest that D. himalayensis should be considered a significant pest of walnut trees, particularly black walnuts, in Europe.

Summary: In this study, we investigated the gallery structure and egg oviposition of the tree-killing bark beetle Polygraphus proximus in its native range. We found that galleries with two arms had significantly more eggs oviposited compared to galleries with one or three arms. Additionally, galleries with no egg oviposition were significantly shorter in length than galleries with more than two arms. Our data suggest that the optimal number of arms in a gallery system for maximum egg oviposition is two.

Summary: Efforts have been made to prevent Asian longhorn beetles from causing harm to forest and urban trees, with over 45% of eradication programmes successful in the last 12 years. Despite the high costs of eradication programs, the benefits outweigh the costs. Eradication efforts for Anoplophora chinensis are more challenging compared to Anoplophora glabripennis.

Summary: This study characterized the mycobiome associated with nettle and poplar roots co-occurring at a trace-metal contaminated site. Nettle was found to have a distinct mycobiome dominated by endophytic Pezizomycetes and saprotrophic genus Kotlabaea, while poplar roots were associated with ectomycorrhizal fungi such as Inocybe and Tuber species. The study also revealed some connections between the mycobiomes of poplar and nettle roots, suggesting a need to reconsider fungal networking beyond known mycorrhizal interactions.

Summary: Sphagnum mosses, as peatland engineers, play a crucial role in carbon accumulation. This review focuses on the effects of elevated temperature, N and CO2 and reduced moisture on the growth and physiological characteristics of three Sphagnum subgenera. Laboratory experiments tend to underestimate maximum photosynthesis and exacerbate length increments compared to in situ experiments. Elevated temperature and N promote growth and photosynthesis, but moisture reduction has different effects on different subgenera. Allelochemical interactions between Sphagnum, their microbiome, and surrounding plants are important factors influencing their responses.

Summary: This article discusses the challenges posed by droughts, wildfires, and windstorms on the adaptability of forest arthropod communities, as well as the influence of disturbance legacies on these communities. The authors highlight the various disturbance legacies and their effects, such as surviving arthropods, micro-environmental legacies, and resources related to trees and the ground. They also emphasize the need for further research on how disturbance legacies impact forest arthropod communities.

Summary: This study identified candidate genes that may play a significant role in spermatogenesis in hymenopterans by comparing taxonomic, phenotypic data, and gene expression. The research found that a large percentage of genes expressed in mice and fruit flies also had orthologs in hymenopteran species, suggesting their importance in testis function in insects. Furthermore, a majority of genes involved in male fertility in Drosophila were found to have orthologs in Hymenoptera species, indicating potential conservation of these genes across different insect taxa.
