Phylogeographische Untersuchungen am Kupferstecher, Pityogenes chalcographus (Coleoptera, Curculionidae)

, 2010
Der Kupferstecher, Pityogenes chalcographus, ist ein phytophager Borkenkäfer der vor allem von der Fichte abhängig ist. Mitte der 1970er Jahre entdeckte man bei P. chalcographus eine unidirektionale Inkompatibilität: Die Kreuzung von zentraleuropäischen Weibchen mit nordeuropäischen Männchen ergab eine reduzierte Nachkommenschaft.

Evidence for low‐titre infections in insect symbiosis: Wolbachia in the bark beetle Pityogenes chalcographus (Coleoptera, Scolytinae)

Environmental Microbiology, 2009
Summary Wolbachia are obligatory endosymbiotic α‐proteobacteria found in many insect species. They are maternally transmitted and often exhibit reproductive phenotypes like cytoplasmic incompatibility.

Differences in bark beetle (Ips typographus and Pityogenes chalcographus) abundance in a strict spruce reserve and the surrounding spruce forests of Serbia

Phytoparasitica, 2010
Frequent windthrow in the strict reserves of spruce in the Kopaonik National Park provides much material favorable for the development of Ips typographus (L.) and Pityogenes chalcographus (L.) (Coleoptera, Scolytidae). Therefore it was assumed that the abundance of these bark beetles in the reserves was high and that they dispersed to the surrounding ...

Reproductive Manipulators in the Bark Beetle Pityogenes chalcographus (Coleoptera: Curculionidae)-The Role of Cardinium, Rickettsia, Spiroplasma, and Wolbachia. [PDF]

J Insect Sci, 2018
Heritable bacterial endosymbionts can alter the biology of numerous arthropods. They can influence the reproductive outcome of infected hosts, thus affecting the ecology and evolution of various arthropod species. The spruce bark beetle Pityogenes chalcographus (L.) (Coleoptera: Curculionidae: Scolytinae) was reported to express partial, unidirectional

Wood decomposition is increased by insect diversity, selection effects, and interactions between insects and microbes

Ecology, Volume 104, Issue 12, December 2023., 2023
Abstract Biodiversity drives ecosystem processes, but its influence on deadwood decomposition is poorly understood. To test the effects of insect diversity on wood decomposition, we conducted a mesocosm experiment manipulating the species richness and functional diversity of beetles.

Spatial distribution of saproxylic beetles on trunks of standing Scots pine trees

Agricultural and Forest Entomology, Volume 25, Issue 4, Page 601-611, November 2023., 2023
Abstract The spatial distribution of saproxylic beetles landing and climbing stems of 12 grown and healthy Scots pine trees (Pinus sylvestris L.) was examined in detail during a 3‐year trial. The beetles were sampled using sticky traps attached to the tree trunk at three tree parts (i.e., the trunk base, middle part of the trunk, and trunk in crown ...
