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 in increased density. The wasps were attracted by the pheromone lure “Chalcoprax” which has kairomonal effect uponK. pityophthori. Investigations with the aid of pheromone baited traps and a new electronical instrument produced detailed knowledge about swarming behaviour and population density of… Expand
Research on Parasitoids and Predators of Scolytidae – A Review
Scolytidae are major forest pests in Europe. For example, Ips typographus (L.) is considered the main pest problem in forestry in many central and northern European countries. Consequently, there isExpand
Synchronous rise and fall of bark beetle and parasitoid populations in windthrow areas
The population level of both groups quickly increased synchronously from the second to the third season, and gradually declined thereafter until the fifth growing season, when the deteriorated phloem quality precludes further bark beetle development. Expand
Natural Enemies of Bark Beetles
The role of these antagonistic agents in bark beetle population dynamics and their potential for use as biological control agents are evaluated based on literature, data from experiments, observations in the field, and from controlled laboratory experiments. Expand

Results show that Nemosoma elongatum can be found in the entire research area with locally high numbers, and that predators being caught with Chalcoprax would partially have fed upon more bark beetles under natural circumstances than were caught in the traps. Expand
Die Lufttemperatur als limitierender Faktor für die Schwärmaktivität zweier rindenbrütender Fichtenborkenkäferarten,lps typographus L. undPityogenes chalcographus L. (Col., Scolytidae)

It could be shown that the flight behaviour of both species of bark beetles was influenced by air temperature and reacted very sensitive and spontaneous to these temperature thresholds. Expand
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. Expand
Populationsdynamik und Räuber-Beute-Beziehung zwischen dem Borkenkäfer-Räuber Nemosoma elongatum und dem Kupferstecher Pityogenes chalcographus (Coleoptera: Ostomidae, Scolytidae)
The population of Nemosoma elongatum increases earlier in spring than that of Pityogenes chalcographus, so reduction of the bark beetle population by predation may therefore be relatively high in V and VI. Expand
Investigations on the life history of Nemosoma elongatum L. (Col., Ostomidae), a bark beetle predator
Abstract: To estimate the influence of N. elongatum on bark beetle (Pityogenes chalcographus), regulation information about the biology of this species is necessary. In the laboratory, embryonicExpand
Untersuchungen zur abundanzdynamischen Relevanz der Beifänge von Nemosoma elongatum (L.) (Col., Ostomidae) in chalcoprax® beköderten Flugbarrierefallen für Pityogenes chalcographus (L.) (Col., Scolytidae)
Studies on the relevance of catching Nemosoma elongatum (L.) (Col., Ostomidae) in chalcoprax® baited traps for population dynamics of Pityogenes chalcographus (L.), Scolytidae, suggest that catching them is more beneficial than reeling them in. Expand
