  abstract = {{I}n the tropics, one successful tool for orchid scientific studies and conservation is the creation of shade houses for ex situ cultivation of regional species. {H}ere, we provide the first comparison of floral scent chemistry in shade houses and natural populations of orchids in central {A}frica. {W}e investigate floral scent variations between two shade houses and one natural site in a sphingophilous epiphytic orchid, {C}yrtorchis letouzeyi, in {C}ameroon. {S}amples were collected in and ex situ through the dynamic headspace method and analyzed using gas chromatography coupled with mass spectrometry. {B}oth composition and relative emission rate were analyzed with temperature and humidity levels recorded at the time of sampling. {T}he floral scent was dominated by both aromatics and isoprenoids and derivatives, including methyl benzoate, linalool, and pyranoid and furanoid forms of linalool oxide. {V}ariations in temperature and humidity had no significant impact on the floral scent composition but on relative emission rates. {S}amples under shade house cultivation produced the same compounds as those in the natural environment. {Q}uantitatively, differences were recorded in the proportions of volatile organic compounds ({VOC}s) produced, but the main compound remained unchanged in both environments. {D}issimilarities were driven by the production of linalool and its derivatives. {B}ased on these findings, we suggest that shade houses are a suitable tool to characterize the qualitative floral scent diversity of tropical epiphytic orchids and can therefore serve to complement in situ sampling.},
