Revista Espinhaço, 2023 Abelhas das orquídeas (Euglossini) compreendem um grupo de abelhas com papel funcional muito importante em ambientes tropicais. Os machos buscam substâncias aromáticas em flores (preferencialmente de orquídeas) e em troca, efetuam a polinização.

Conservation Value and Permeability of Neotropical Oil Palm Landscapes for Orchid Bees [PDF]
, 2013 The proliferation of oil palm plantations has led to dramatic changes in tropical landscapes across the globe. However, relatively little is known about the effects of oil palm expansion on biodiversity, especially in key ecosystem-service providing ...

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]
, 2015 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

Microbial Evolution in Allodapine Bees: Perspectives From Trophallactic, Socially Plastic Pollinators. [PDF]
Evol ApplABSTRACT This review seeks a deeper functional understanding of wild bee microbiomes by focusing on a tribe of bees where natural history and behavioral ecology are well known but investigations of microbiology are just beginning. Opportunities to improve our future knowledge of pathogens to insect pollinators are explored—which have broad ...

Suction feeding in orchid bees (Apidae: Euglossini) [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004 Energy flux during nectar feeding is maximized at an intermediate sugar concentration, the value of which depends on the morphology of the feeding apparatus and the modality of fluid feeding. Biomechanical models predict that a shift from capillary-based lapping to suction feeding will lead to a decrease in this optimal sugar concentration.

24 million years of pollination interaction between European linden flowers and bumble bees. [PDF]
New PhytolSummary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.
