Acompocoris pygmaeus
minute pirate bug
Acompocoris pygmaeus is a minute pirate bug in the family Anthocoridae. It is native to Europe, Northern Asia (excluding China), and North America. The species has a documented association with Scots pine (Pinus sylvestris), suggesting a specialized ecological relationship with this conifer host.
Pityogenes bidentatus
Pityogenes bidentatus is a European bark beetle that colonizes Scots pine (Pinus sylvestris). The species exhibits sophisticated olfactory-mediated behaviors for host location, including attraction to aggregation pheromone components (grandisol and cis-verbenol) and active avoidance of nonhost volatiles. Its behavioral response to monoterpene odors is context-dependent: avoidance occurs during flight but not during walking, likely representing distinct sensory mechanisms for long-range host discrimination versus short-range gallery establishment.
