Hylurgops is a of bark beetles in the Curculionidae. in this genus are distributed across Eurasia and North America. Members are phloeophagous, feeding on the inner bark of coniferous trees. selection is chemically mediated, with species responding to specific monoterpene cues from host trees.

Habitat

Inner bark (phloeophagous ) of coniferous trees; associated with Pinus and Picea based on documented records.

Distribution

Eurasia and North America; documented occurrence in Denmark, Norway, Sweden, Poland, and the United States (Vermont).

Diet

Phloeophagous; feeds on inner bark of coniferous trees.

Host Associations

  • Pinus sylvestris - Documented for H. palliatus in Poland
  • Picea abies - Preferred for H. palliatus based on olfactory response studies
  • Picea - Primary for H. palliatus

Behavior

selection mediated by olfactory response to monoterpene chemical cues. Hylurgops palliatus has been observed to respond preferentially to host-specific odor signals and avoid volatiles from non-host conifers. Attraction to specific compounds including β-pinene, terpinolene, and myrtenol has been documented.

Ecological Role

of fungal associates; transport ophiostomatoid fungi including Leptographium lundbergii, Ophiostoma minus, and O. piceae to trees.
