| Abstract: | "Longhorned beetles (Cerambycidae) are a diverse family of wood-boring insects, many species of which produce volatile pheromones to attract mates over long distances. The composition and structure of the pheromones remain constant across many cerambycid species, and comparative studies of those groups could, therefore, reveal the chemoreceptors responsible for pheromone detection. Here, we use comparative transcriptomics to identify a candidate pheromone receptor in the large and economically important cerambycid genus Monochamus, males of which produce the aggregation-sex pheromone 2-(undecyloxy)-ethanol ('monochamol'). Antennal transcriptomes of the North American species M. maculosus, M. notatus, and M. scutellatus revealed 60-70 odorant receptors (ORs) in each species, including four lineages of simple orthologs that were highly conserved, highly expressed in both sexes, and upregulated in the flagellomeres where olfactory sensilla are localized. Two of these orthologous lineages, OR29 and OR59, remained highly expressed and conserved when we included a re-annotation of an antennal transcriptome of the Eurasian congener M. alternatus. OR29 is also orthologous to a characterized pheromone receptor in the cerambycid Megacyllene caryae, suggesting it as the most likely candidate for a monochamol receptor and highlighting its potential as a conserved lineage of pheromone receptors within one of the largest families of beetles" |
