Effects of Ips typographus (L.) and sanitation logging disturbance on organic matter decomposition and carbon in the humus layer in boreal Picea abies (L.) H. Karst. stands

Annals of Forest Science
Key message Sanitation logging, aimed at mitigating the spread of European spruce bark beetle (Ips typographus L.) outbreaks in boreal stands, was associated with increased decomposition and loss of carbon from the humus layer, measured 10 years post ...

Exploitation of kairomones and synomones by Medetera spp. (Diptera: Dolichopodidae), predators of spruce bark beetles

European Journal of Entomology, 2005
The semiochemical relationships in a predator-prey-host plant system were studied by a series of multiple-choice field assays. The studied system included predatory flies of the genus Medetera (Diptera: Dolichopodidae), the bark beetles Ips typographus ...

Regulating bark beetles with mechanical bark treatments: Trade‐offs among pest control, operational efficiency and biodiversity

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Three times harvester processing and motor‐manual bark gouging effectively reduce bark beetles, enabling two options: permanent on‐site retention for biodiversity conservation, or up to 2 years of intermediate on‐site storage with no treatment effect on blue‐stain fungi colonization or energy content, thereby buffering operational bottlenecks during ...

From forest stand decline to salvage logging: Cascading impacts on saproxylic beetle diversity

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Given the pronounced context dependency of the processes driving these cascading community dynamics, and considering the increasing frequency, severity and spatial extent of forest disturbances and global stand decline, it is imperative to integrate this complexity into management and conservation frameworks.

Effect of insecticide-treated trap logs and lure traps for Ips typographus (Coleoptera: Curculionidae) management on nontarget arthropods catching in Norway spruce stands

Journal of Forest Science, 2014
The numbers of nontarget arthropods captured by Theysohn pheromone traps (TPTs) and insecticide-treated tripod trap logs (TRIPODs) were compared; both kinds of traps were baited with pheromone lures Pheagr IT for Ips typographus.

Multi‐Omics Profiling of the Scaphoideus titanus Yeast‐Like Symbiont Guides the Bioinformatic Discovery of Related Fungal Symbioses in Insects

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Genomic, proteomic and phylogenetic analyses of the obligate yeast‐like symbiont (YLS) associated with Scaphoideus titanus revealed retained metabolic flexibility and a monophyletic origin of insect‐associated YLSs within a free‐living fungal lineage. A novel computational pipeline was used to mine NCBI transcriptomic data and identified new candidate ...

Therapeutic Bark Gouging as an Effective Complement for the Management of Ips typographus and Pityogenes chalcographus While Preserving Habitat for Secondary Scolytine (Coleoptera: Curculionidae) Species

Journal of Applied Entomology, Volume 150, Issue 6, Page 780-790, July 2026.
ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Behavioral responses of predatory flies of the genus Medetera Fischer von Waldheim (Diptera: Dolichopodidae) and the tree-killing beetle Ips typographus L. (Coleoptera: Scolytinae) to odor compound blends

Annals of Forest Science
Key Message Medetera (Fischer von Waldheim) flies, natural enemies of the spruce bark beetle Ips typographus (L.), were attracted to synthetic blends of compounds produced by infested spruce trees.

Comparative analysis of olfactory sensory neurons in two Ips species reveals conserved and species-specific olfactory adaptations

Frontiers in Forests and Global Change
IntroductionBark beetles spend most of their lives under the bark of trees, with some species being economically significant pests that cause widespread tree mortality.

Multi‐Omics Analyses Elucidate the Venom Components of the Wasp Vespa mandarinia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The wasp Vespa mandarinia was widely reared in Yunnan province. The venom was responsible for their aggressive behavior. Tweety proteases, hyaluronidase, venom dipeptidyl peptidase 4, and phospholipase A1 and A2 isozyme were identified. In addition, organic heterocyclic compounds, organic acids, and derivatives were found.
