The flowers of the sexually deceptive orchid Ophrys sphegodes are pollinated by pseudocopulating males of the solitary bee Andrena nigroaenea. We investigated the changes in odor emission and reduced attractiveness that occur after pollination in these plants. We analyzed floral odor of unpollinated and pollinated flowers by gas chromatography and compared relative and absolute amounts of electrophysiologically active compounds. Headspace odor samples of O. sphegodes flowers showed a… CONTINUE READING
