The Chemical Ecology of the Missouri Native Glade Species Manfreda virginica and its Moth Pollinators.

Floral organic volatile (FOV) emissions can vary in composition both spatially and temporally within a flower, and impact plant-pollinator systems. In the glade species Manfreda virginica, a protanderous and fragrant nocturnal plant, we examined the FOV emission of flowers during its two reproductive stages using solid-phase micro-extraction (SPME) and gas chromatography-mass spectrometry (GCMS) techniques. We conducted olfactometer bioassays with naïve and experienced visitors to determine the behavior of visitors in response to collected volatile compounds. We conducted pollinator observations, hand pollinations treatments, and fluorescent microscopy of pollen tube squashes to determine the primary pollinator of this plant, and whether or not it is experiencing pollen limitation. Early results indicate that this plant is pollinated primarily by moths in the families Sphingidae and Noctuidae.
