Deceptive orchids

Hundreds of deceptive orchid species use odor and other cues to mimic general and specific floral food sources, oviposition sites, and female insects (Gill, 1989 Nilsson, 1992). Moya and Ackerman (1993) observed species-level qualitative and... [Pg.161]

Flowers of some orchids mimic both the appearance and sex pheromone of virgin females of certain species of bees or wasps. This sexual deception results in pollination by male hymenoptera that would not normally visit flowers. Japanese honey bee drones (Apis cerana japonica) cluster on the oriental orchid (Cymbidiumpumilum) while on their mating flights [ 134]. By comparing volatile profiles of orchids and the female hymenoptera they mimic, or by GC-EAD and GC-MS analysis of orchid volatiles, several compounds have been identified that may mediate this attraction for the solitary bee Andrena nigroaenea [135, 136] and the scoliid wasp Campsoscolia ciliata [135]. [Pg.173]

Orchids of the Mediterranean genus Ophrys and several Australian genera, including Cryptostylis and Caladenia, have converged upon a remarkable category of deception - pseudocopulation - because their flowers use odor, visual, and tactile cues to mimic female hymenoptera (reviews Staudamire, 1983 Borg-Karlson,... [Pg.162]

Several orchids have remarkably characteristic pollination systems employing sexual deception in this system, the flowers mimic the visual, tactile, and olfactory traits of the females of particular hymenopteran species and so deceive conspecific males into attempting to mate with the flowers. In particular, the floral scent, which has a composition identical to that of female sex pheromones, is a key mediator of this exclusive and species-specific mode of pollination. [Pg.581]

Certain species even divert other types of scents in this domain, orchids display a wide diversity of olfactory deception strategies. There exists first in... [Pg.9]
