Cambioxylophagous fauna of young spruce stands damaged by snow in the Beskids
In 25 to 40-years-old stands damaged by snow in the Beskids, the fauna of cambioxylophages was analyzed both on standing breaks and lying break-off stems.

Abstract The purpose of the study was to develop, calibrate and validate a comprehensive phenological model for the spatiotemporal simulation of the seasonal development of the six-toothed spruce bark beetle, Pityogenes chalcographus (CHAPY). The validation dataset was acquired through monitoring of the bark beetle's phenology at eight sites in ...

Non-target Bark Beetles in Ips duplicatus (Sahlberg) Pheromone Traps Baited with Host Volatiles
Response of several non-target bark beetles (Coleoptera: Curculionidae, Scolytinae) to different combinations of the northern spruce bark beetle’s synthetic pheromone with the monoterpenes (-)-alpha-pinene and (+)-limonene has been studied in choice ...

Contribution to the fauna and bionomics of entomophagous insects feeding on the small spruce bark beetle Ips amitinus (Eichh.) (Coleoptera, Curculionidae: Scolytinae) in West Siberia [PDF]
A total of 29 species of entomophagous insects from 15 families of 4 orders were found for the fi rst time in the galleries of the small spruce bark beetle Ips amitinus within its invasive range in West Siberia; 26 species were predators of Ips amitinus,

Identifizierung von Haplotypen bei Pityogenes chalcographus (Col., Scolytidae) durch SSCP [PDF]
Pityogenes chalcographus is a widely distributed spruce pest in Eurasia (KNIZEK et al. 2005). In 70ies, E. Führer studied the intraspecific variation of this spruce bark beetle and detected race differentiation among European populations based on ...

Automatic traps foster the monitoring and prediction of bark beetle swarming
Automated trap data help bark beetle management to act more timely and targeted, thereby facilitating an effective mitigation of outbreaks. Moreover, the immediate data transmission makes regular manual trap collections unnecessary. While swarming models cannot quantify absolute trap catches without site‐ and trap‐specific calibration, they provide ...
