New parasitoid (Hymenoptera, Chalcidoidea) records of bark beetles (Coleoptera, Curculionidae, Scolytinae) in pine plantations in Bulgaria [PDF]

Biodiversity Data Journal, 2023
In 2020 and 2021, chalcidoid parasitoids (Hymenoptera, Chalcidoidea) of bark beetles in pine (Pinus spp.) plantations were studied in Bulgaria. Samples (cuttings of stems and branches) of pine trees infested by bark beetles were collected from seven ...

Evolutionary ecology of the bark beetles Ips typographus and Pityogenes chalcographus

Bulletin of Entomological Research, 2022
Ips typographus (L.) and Pityogenes chalcographus (L.) (Coleoptera: Curculionidae) are two common bark beetle species on Norway spruce in Eurasia. Multiple biotic and abiotic factors affect the life cycles of these two beetles, shaping their ecology and ...

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

New Canadian and Provincial Records of Coleoptera Resulting from Annual Canadian Food Inspection Agency Surveillance for Detection of Non-Native, Potentially Invasive Forest Insects [PDF]

Insects, 2022
The arrival and establishment of adventive, invasive forest insects are a threat to the health, diversity, and productivity of forests in Canada and the world at large, and their early detection is essential for successful eradication and management. For

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.

Natural-history traits suspected behind interspecific variations of bark- and wood-boring beetles in response to trap size and design [PDF]

Scientific Reports
The 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 ...
