Highly Expressed Odorant Receptor Orthologs Detect the Aggregation Pheromone Lineatin in Trypodendron Ambrosia Beetles.

ABSTRACT: Chemical communication using pheromones is crucial for the reproductive success of many insect species, including beetles (Coleoptera). Pheromones are detected by specialised odorant receptors (ORs), called pheromone receptors (PRs), in the sensory neurons of the antennae. The PRs in Coleoptera remain understudied, with only a few receptors being functionally characterised. This limits our understanding of their response specificities and evolutionary origins. To this end, we aimed to identify PRs in two species of ambrosia beetles (Curculionidae; Scolytinae), the conifer-attacking Trypodendron lineatum ('Tlin') and the congener T. domesticum ('Tdom'), specialising in deciduous trees. Both species use the female-produced aggregation pheromone lineatin for host- and mate finding. To date, n
