Single catches of bark beetles in pheromone baited traps were registered by the aid of a new instrument. It consists of an electronical weather station in connection with a pheromone trap with infrared sensors as additional equipment. So it was possible also to register weather data at the moment of every catching event. It could be shown that the flight behaviour of both species of bark beetles was influenced by air temperature.I. typographus did not fly beneath a minimum temperature of 16.5°C… 
Untersuchungen zum Einfluß von Sonnenlicht auf das Schwärmverhalten von Borkenkäfern
With the aid of eletronic registration equipment and other experimental methods, it could be shown that the flight behaviour of spruce bark beetles to pheromone sources is strongly influenced by the
Schwärmverhalten und Abundanzdynamik der ErzwespeKarpinskiella pityophthori (Bouček) (Hym., Pteromalidae), eines Parasitoiden des Kupferstechers (Pityogenes chalcographus L., Col., Scolytidae)
During a mass propagation ofPityogenes chalcographus in Southern Bavaria the pteromalid waspKarpinskiella pityophthori Bouček, a parasitoid of the bark beetle which is not very well known, occurred
PHENIPS—A comprehensive phenology model of Ips typographus (L.) (Col., Scolytinae) as a tool for hazard rating of bark beetle infestation
Using topoclimatic data, PHENIPS simulates the maximum number of generations which is necessary to assess the potential impact of bark beetle outbreaks at regional scale and can be used for precise monitoring of the actual state of bark beetles development at the specific stand/tree level.
Laboratory Evaluation of Flight Activity of Dendroctonus armandi (Coleoptera: Curculionidae: Scolytinae)
From the data collected, it is clear that the phototactic response is an important factor in the flight behaviour of D. armandi and may influence its spatial dispersal.
Diapause and overwintering of two spruce bark beetle species
The influence of diapause and overwinter survival on voltinism and population dynamics of these two species in a changing climate are discussed and compared, and an outlook on future research is provided.
The spruce bark beetle Ips typographus in a changing climate
Outbreaks of the Spruce bark beetle Ips typographus are often triggered by storm and drought and have destroyed millions of cubic meters of wood. It is therefore a pest insect of economic importance
Physiology of cold tolerance in the bark beetle, Pityogenes chalcographus and its overwintering in spruce stands.
The physiological limits of cold tolerance measured at individual level in laboratory were safely sufficient for survival of P. chalcographus at any conceivable cold spell that may occur in Central Europe.
Effects of volatile emissions of Picea abies fresh debris on Ips duplicatus response to characteristic synthetic pheromone.
It was found that Ips duplicatus beetles, regardless of sex, have been concentrated in areas where large amounts of fresh material were available, confirming that Ips duplication beetles are using both natural pheromones and specific host volatiles as olfactory stimuli in searching for breeding material.
Ecology and management of the spruce bark beetle Ips typographus—a review of recent research
The outbreaks of Ips typographus (L.) in Central Europe after severe storms in the 1990s triggered extensive research. Molecular techniques were used to analyze the relations and origins of European
Seasonal flight patterns of Ips typographus in southern Sweden and thermal sums required for emergence
Knowledge of these region‐specific flight patterns and the associated thermal sums required for emergence will facilitate efficient pest management by enabling timely removal of fallen and standing weakened host trees.


Untersuchungen zum Anflugverhalten des Kupferstechers (Pityogenes chalcographus L.) und einiger Beifänge an Pheromonfallen mit Hilfe eines neuartigen elektronischen Meßgerätes
It could be shown that each of these species has a characteristical threshold of temperature for the beginning of its flight activity and also the day time had a great influence on the swarm activity of the investigated species.
A model for the temperature and density dependent reemergence of the bark beetle Ips typographus
The model was in good agreement with the reemergence pattern found for two groups of infested logs under different temperature conditions when adjusted for the lower breeding density, and should be useful in developing other models for poikilothermic processes.
Monitoring bark beetle populations: effects of temperature 1
Annual catches of the spruce bark beetle Ips typographus in pheromone‐baited traps were largely unaffected by the current season temperature, andalyses of temperature parameters from the previous year indicate a significant correlation between May‐June temperatures and trap catches.
