Different Pollinators’ Functional Traits Can Explain Pollen Load in Two Solitary Oil-Collecting Bees [PDF]

Insects, 2020
Functional traits have been shown to be a good predictor of pollen load for some pollinator bee species, but little is known about solitary bees. In this study, I used two solitary oil-collecting bees to explore the impact of functional traits on the ...

Structural and Functional Co‐Adaptation of Plants of the Genus Lysimachia L. (Primulaceae) and Pollinating Insects of the Genus Macropis Panzer (Hymenoptera, Melittidae) [PDF]

Ecology and Evolution
The pollination system ‘oil‐collecting bees Macropis and oil‐producing plants Lysimachia’, probably originated a long time ago. Although much is already known about the biology and ecology of this fascinating interaction, we reveal here features of the ...

The primary types of some species of Centris bees described by European entomologists in the 18th and 20th centuries (Hymenoptera: Apidae)

European Journal of Taxonomy, 2023
In this paper are presented notes on the primary types of some species of the oil-collecting bees of the genus Centris described by the European naturalists and entomologists Amédée Louis Michel Lepeletier de Saint-Fargeau, Anders Christian Jensen ...

Comparison of Pollen-Collecting Abilities between Apis mellifera L. and Bombus terrestris L. in the Oil Tree Peony Field

Horticulturae, 2023
The lack of pollinators in the oil tree peony field was a serious problem for the seed yield. In the preliminary studies, we found that the seed rate of oil tree peonies was significantly improved by supplementing bees during the flowering stages in the ...

Chemical Characterisation of the Floral Oil of the Murici (Byrsonima sericea): Discovering the Constituents Used in Reproduction by Oil-Collecting Bees

Sociobiology, 2020
The recent decline in population of generalist bees such as those of the genera Apis and Bombus has shown the need to breed and manage a larger number of bee species.

The species of the bee genus Centris of the “hyptidis group” revisited with the description of Centris (Anisoctenodes) new subgenus (Hymenoptera: Apidae: Centridini)

European Journal of Taxonomy, 2020
In this paper, the species of Centris of the “hyptidis group” are revisited, proposing to recognize them as members of Anisoctenodes subgen. nov., a new subgenus supported by morphological and molecular data. The species included in this new taxon are C.

Oil collecting bees and Byrsonima cydoniifolia A. Juss. (Malpighiaceae) interactions: the prevalence of long-distance cross pollination driving reproductive success

Anais da Academia Brasileira de Ciências, 2014
Oil-collecting bees are the natural pollinators of oil-flower plants, but little is known about the pollination process and the effectiveness of their pollination service to the reproductive success of their host plants.

The Similar Usage of a Common Key Resource Does Not Determine Similar Responses by Species in A Community of Oil-collecting Bees

Sociobiology, 2017
Variations in abundance and species richness among communities are often determined by interactions between biotic and abiotic factors. However, for communities composed of species that share a common specialization (such as similar foraging adaptations)

Bee Life in the City: an Analysis of the Pollen Provisions of Centris (Centris) flavifrons (Centridini) in an Urban Area

Sociobiology, 2017
Due to deforestation and fragmentation of ecosystems, the management of bee populations targeting pollination services is increasingly urgent. Because urban environments are stressful, the dietary knowledge in such areas can help to cope with this issue ...
