AbstractThe impact of pollinator community diversity on trait matching in plant-pollinator interactions is poorly studied, even though many mutualisms involve multiple interaction partners. We studied 10 communities in which one to three species of oil-collecting Rediviva bees pollinate the long-spurred, oil-producing flowers of Diascia "floribunda" to

Reproductive biology of Trichocentrum pumilum: an orchid pollinated by oil‐collecting bees
Plant Biology, 2010AbstractThe reproductive biology, reward production and pollination mechanism of Trichocentrum pumilum were studied in a gallery forest in the interior of the State of São Paulo, southeast Brazil. The floral visitors and pollination mechanism were recorded, and experimental pollinations were carried out in order to determine the breeding system of this

Arthropod-Plant Interactions, 2020
In plant–pollination interactions, the antagonists collect the same set of resources offered to legitimate visitors, but their morphologies and behavioural approaches possibly make their effect on plant fitness negative rather than positive. Depending on the morphology of Malpighiaceae flowers, these small-bodied bees can adopt an upside-down position,

Zootaxa, 2016
Centris dimidiata (Olivier) is currently considered an easily recognizable species widely distributed throughout the Amazon basin, mainly in Brazil. For much of its taxonomic history, C. atriventris Mocsáry and C. furcata (Fabricius) have been considered its junior subjective synonymies.

Abstract The species of Rediviva (Apoidea, Melittidae) occurring in the summer rainfall region of South Africa are revised. Nine species are recognized, four are described as new: R. brunnea, R. autumnalis, R. rhodosoma and R. transkeiana all attributed to Whitehead and Steiner.

Abstract: The pollination of Angelonia cornigera Hook. (Scrophulariaceae) was studied in Caatinga vegetation, in the municipality of Buíque, Pernambuco state, northeastern Brazil. The plant is a perennial of open areas. Up to 60 flowers are produced in terminal, leafy racemes.

Journal of economic entomology, 2009
Acerola (Malpighia emarginata DC; Malpighiaceae) is an important fruit crop in Brazil. Among its pollinators, Centris (Heterocentris) analis (F.) stands out due to its abundance at flowers and prompt acceptance of trap-nests. For the first time, we propose the commercial use of Centris bees as orchard pollinators.

AbstractCentris (Wagenknechtia) is the only subgenus of centridine bees that occurs almost exclusively in the Andean Region. This study investigates the monophyly of C. (Wagenknechtia) proposing a hypothesis for the relationships among its species using 42 morphological characters of adults.
