Oriental Orchid (Cymbidium floribundum) Attracts the Japanese Honeybee (Apiscerana japonica) with a Mixture of 3-Hydroxyoctanoic Acid and 10-Hydroxy-(E)-2-Decenoic AcidZoolog Sci, 2013 Feb;30(2):99-104The flower of the oriental orchid Cymbidium floribundum isknown to attract the Japanese honeybee Apis cerana japonica. This effect isobserved not only in workers but also drones and queens; that is, it attractseven swarming and absconding bees. A mixture of 3-hydroxyoctanoic acid (3-HOAA)and 10-hydroxy-(E)-2-decenoic acid (10-HDA) was identified as the activeprinciples from the orchid flower, whereas these compounds individually have nosuch activity. Both compounds are also mandibular gland components of workerhoneybees with related compounds. This strongly supports the idea that orchidflowers mimic bee secretions, although the ecological consequences of thisrelationship remain unknown. Because the flower is used to capture swarms, thepresent identification may contribute to the development of new techniques intraditional beekeeping for Japanese bees as well as A. cerana in SoutheastAsia.
