Spatial and temporal patterns of floral scent emission in Dianthus inoxianus and electroantennographic responses of its hawkmoth pollinator

► Dianthus inoxianus flowers emit scent throughout the night and the day. ► D.inoxianus floral scent is dominated by 2-ketones and (E,E)-farnesol. ► D.inoxianus nectar scent is dominated by Benzaldehyde and Phenylacetaldehyde. ► 2-Ketones and sesquiterpenoids elicit electroantennographic responses Hyles livornica. ► 2-Ketones emission is boosted by mechanical damage.
