Pollination by Euglossine Bees [PDF]
The relationships between some orchid flowers and male euglossine bees were first observed in Darwin's time (Criiger, 1865), but the peculiarities of these interactions have been recognized only within the last decade. Our knowledge of the relationships has increased greatly in recent years, especially through the efforts of Dodson (Dodson and Frymire,

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Forest patch isolation drives local extinctions of Amazonian orchid bees in a 26 years old archipelago [PDF]
Major hydroelectric dams are among key emergent agents of habitat loss and fragmentation in lowland tropical forests. Orchid bees (Apidae, Euglossini) are one of the most important groups of specialized pollinators of flowering plants in Neotropical ...

The solitary or colonial Euglossini (Apidae) are important pollinators of many planes of low and middle elevation, neotropical forests. The bees are wary, rapid fliers, and capable of flying long distances. The tribe is perhaps best known for the fragrance-colleaing activities of males, particularly at orchid flowers (e.g., Dressler 1968, Dodson et al .

Does the waggle dance help honey bees to forage at greater distances than expected for their body size? [PDF]
A honey bee colony has been likened to an oil company. Some members of the company or colony prospect for valuable liquid resources. When these are discovered other group members can be recruited to exploit the resource. The recruitment of nestmates to a

Nonfloral sources of chemicals that attract male euglossine bees (Apidae: Euglossini) [PDF]
We present chemical analysis of four rotten or fungus-infected logs that attracted fragrance-collecting male euglossine bees. Eight of the 10 volatile compounds detected have never been found in the fragrances of orchids pollinated by male euglossine bees.

Presence of Euglossa (Euglossa) amazonica outside of the Amazon Basin – biogeographic insights [PDF]
Distributional patterns of euglossine bees are often shadowed by the most noticeablefeatures of the group, their morphology and behavior. With the constant discovery of records ofeuglossine species in novel localities, and the ongoing systematic work in ...

Composition of Orchid Scents Attracting Euglossine Bees
AbstractFragrance composition of flowers from 101 plant species, especially orchids, were analyzed. Several compounds, including allo‐aromadendrene, β‐bourbonene, α‐copaene, α‐cubebene, 1,2‐dimethoxybenzene, 1,3,5‐trimethoxybenzene, epoxygeranyl acetate, 7,11‐epoxymegastigma‐5(6)‐en‐9‐one, two γ‐lactones, germacradienol, germacrene D, humulene, methoxy‐

Orchid Bees (Hymenoptera: Apidae: Euglossini) in Seasonally Dry Tropical Forest (Caatinga) in Brazil
Euglossini bees are important Neotropical pollinators, but there is a lack in the knowledge about this fauna in dry tropical environments. The aims of this study were to evaluate the richness and abundance of euglossine bees in two fragments of ...
