Pathogens of the spruce bark beetles Ips typographus and Ips duplicatus
Abstract Pathogens of two important bark beetles, Ips typographus and Ips duplicatus, both in outbreaks connected with infestation of spruces by the fungus Armillaria ostoyae, were compared at four localities in the eastern Czech Republic.

Mechanisms of Odor Coding in Coniferous Bark Beetles: From Neuron to Behavior and Application
Coniferous bark beetles (Coleoptera: Curculionidae: Scolytinae) locate their hosts by means of olfactory signals, such as pheromone, host, and nonhost compounds. Behavioral responses to these volatiles are well documented.

Efficacy of synthetic lures for pine bark beetle monitoring
The Scots pine (Pinus sylvestris) plantations in central Europe are currently damaged by a large-scale infestation by bark beetles (Scolytinae). Ips acuminatus and Ips sexdentatus are among the most aggressive species causing infestations of pine trees ...

Results of monitoring of xylophilous beetles with pheromone traps in the Botanical Garden of PetrSU
The taxonomic list of xylophilous hardflies recorded in the Botanical Garden of PetrSU contains 17 species from 8 families. Insects were collected using barrier traps with aggregation pheromones synthesized by FGBU VNIIKR (bark beetle Ips typographus ...
