Pityogenes
bark beetles
Pityogenes is a genus of bark beetles in the family Curculionidae, comprising over 30 described species distributed across the Northern Hemisphere. Species in this genus are primarily associated with coniferous trees, with P. chalcographus being the most extensively studied due to its economic significance as a pest of Norway spruce. The genus exhibits typical scolytine characteristics including aggregation pheromone communication and specialized host-finding behaviors. Some species demonstrate notable geographic variation in morphology and genetics, suggesting population differentiation across their ranges.
Pronocera
Pronocera is a genus of long-horned beetles (Cerambycidae) established by Motschulsky in 1859. The genus contains three described species: Pronocera angusta, P. collaris, and P. sibirica. Pronocera angusta has been studied in detail for its morphology, phenology, and ecology in relation to Norway spruce forests. The genus belongs to the tribe Callidiini within the subfamily Cerambycinae.
