Pleistocene climate cycling and host plant association shaped the demographic history of the bark beetle Pityogenes chalcographus. [PDF]
Sci Rep, 2018 AbstractHistorical climatic oscillations and co-evolutionary dependencies were key evolutionary drivers shaping the current population structure of numerous organisms. Here, we present a genome-wide study on the biogeography of the bark beetle Pityogenes chalcographus, a common and widespread insect in Eurasia.

Polyploid spermatozoa in Pityogenes chalcographus and Ips typographus (Coleoptera: Scolytidae) [PDF]
European Journal of Entomology, 2004 Abnormal spermatogenesis in Pityogenes chalcographus (L.) and Ips typographus (L.) results in oversized spermatozoa in all the populations investigated. They can be identified by light microscopy and classified as 2n up to 16n polyploid.

Linoleic Acid Promotes Emission of Bark Beetle Semiochemicals by Fungal Symbionts. [PDF]
J Chem Ecol, 2023 Tree-killing bark beetles in conifer forests vector symbiotic fungi that are thought to help the beetles kill trees. Fungal symbionts emit diverse volatile blends that include bark beetle semiochemicals involved in mating and host localization.

Mitochondrial phylogenies in the light of pseudogenes and Wolbachia: re-assessment of a bark beetle dataset [PDF]
ZooKeys, 2010 Phylogenetic studies based on mtDNA become increasingly questioned because of potential pitfalls due to mitochondrial pseudgenes and mitochondrial selective sweeps.

The Apennines as a cryptic Pleistocene refugium of the bark beetle <i>Pityogenes chalcographus</i> (Coleoptera: Curculionidae). [PDF]
Biol J Linn Soc Lond, 2019 The Apennine Mountains in Italy are an important biogeographical region and of particular interest in phylogeographical research, because they have been a refugium during Pleistocene glaciation events for numerous European species. We performed a genetic study on the Eurasian bark beetle Pityogenes chalcographus (Linnaeus, 1760), focusing on two ...

The relationships between Pityogenes chalcographus and Nemosoma elongatum in clear-cuts with different types of management [PDF]
Plant Protection Science, 2020 Pityogenes chalcographus (Linnaeus, 1758) is a significant pest of young spruce stands up to the age of about 20 years. Predation can be a significant part of decreasing its population density.

Attractiveness of Picea pungens to the bark beetle species Ips amitinus (Eichh.) and Pityogenes chalcographus (L.) [PDF]
Journal of Forest Science, 2013 Only two cambioxylophagous species (Ips amitinus and Pityogenes chalcographus) were found on sections of Picea pungens and Picea abies that belong to economically important pests of Norway spruce. Representatives of the Isarthron sp.

Natural-history traits suspected behind interspecific variations of bark- and wood-boring beetles in response to trap size and design [PDF]
Scientific ReportsThe performances of traps used for pest monitoring are not well understood. Variable trap sizes and shapes make cross-comparisons difficult. We tested with four Scolytinae species (Coleoptera, Curculionidae) a set of traps of the same model (fan-traps ...
