Title Floral synomone diversification of sibling Bulbophyllum

parts of the orchid flowers that are involved in attracting and entrapping a fly during pollination are petals, medial and lateral sepals, lip and column (Fig. 2A). For chemical analysis of the floral scents, freshly bloomed flowers (wrapped in fine netting and prevented from insect visitation) were sampled

Pollination ecology of the Neotropical gesneriad Gloxinia

Pollination by perfume-collecting euglossine males occurs in about 850 species (Ramırez 2009). This pollination syndrome is far more common among orchids thus the colloquial name orchid bees but is also reported in many other families, such as Araceae, Arecaceae, Euphorbiaceae, Solanaceae and Gesneri-

Orchid bees (Hymenoptera, Apidae, Euglossini) are seasonal in

Orchid bees (Euglossini) are rather known for their males which collect aromatic compounds from different plant families (mainly Orchidaceae) and store these compounds in their highly mod-ified hind tibia for further attracting females (Roubik & Hanson, 2004). There are about 230 species of orchid bees, distributed among five

euglossine bees were captured with an entomological net as they arrived at the chemical baits. The baits were replenished once an hour due to the volatility of the scents. Local temperature was measured every 30 minutes during the sampling period. Bees were identified in the laboratory and deposited in the

euglossine bees [41]. Male orchid bees were sampled from each site multiple (5-9) times between Oct 1 and Nov 16, 2014. All collections occurred between 8:30 and 11:30 a.m., roughly corresponding to peak daily abundance. Bees were sampled by saturating tissue paper with one of two compounds (cineole or methyl salicylate), and

Floral scent emission and pollinator attraction in two

Abstract We investigated scent composition and polli-nator attraction in two closely related orchids, Gymna-denia conopsea (L.) R.Br. s.l. and Gymnadenia odoratissima (L.) Rich. in four populations during the day and night. We collected pollinators of both species using hand nets and sampled floral odour by headspace sorption.

Floral Scent Emission and Pollinator Attraction in Two

orchids pollinated by euglossine bees in tropical America (Dodson et al. 1969). Quantitative differences were found to be prominent in the scents of Gymnadenia conopsea and G. odoratissima, that produce largely the same set of odour compounds (Kaiser 1993). In this study, we investigated how pollinator attrac
