Generalist Bee Species on Brazilian Bee‐Plant Interaction Networks

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Determining bee and plant interactions has an important role on understanding general biology of bee species as well as the potential pollinating relationship between them. Bee surveys have been conducted in Brazil since the end of the 1960s. Most of them applied standardized methods and had identified the plant species where the bees were collected ...

Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate

open access: yesRevista Ciência Agronômica, 2019
Pollination is a key factor in global agricultural production, and there is a need to increase the number of bee species that can be bred for pollination in agriculture, such as the oil-collecting solitary bee Centris (Heterocentris) analis (Fabricius ...

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Male sleeping aggregations of solitary oil-collecting bees in Brazil (Centridini, Tapinotaspidini, and Tetrapediini; Hymenoptera: Apidae)

open access: yesGenetics and Molecular Research, 2009
Males of solitary bees usually spend the night in clusters on small branches of plants, cavities and flowers. The individuals usually return to the same location each evening during their life, exhibiting site fidelity to a particular plant. We report on the sleeping roosts of the males of some oil-collecting bees of the genera Centris, Paratetrapedia,

Diversity and temporal variation of bees of the genus Centris (Hymenoptera: Apidae: Centridini) in the dry forest ecosystem Tatacoa Desert (Neiva-Huila) [PDF]

open access: yes, 2017
El género Centris es un grupo de origen neotropical, considerado un polinizador importante de varios ecosistemas. A pesar de su importancia, en Colombia es poca la información relacionada sobre su diversidad, particularmente en la zona sur del país ...

High visitation rate of oil bees may increase pollination efficiency of Couepia uiti in Pantanal wetland [PDF]

open access: yes, 2018
International audienceAbstractPollen transfer to the stigma is the primary mechanism of sexual reproduction in plants. Among bee species that act as pollen vectors and pollinators, attributes such as floral visitation rate, synchrony with the receptive ...

Complex interactions in ant–plant mutualisms: The role of multiple ant food resources in mediating plant defence, pollination and fitness in a tropical shrub

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1137-1147, December 2025.
Our results show that ants reduced leaf herbivory on plants offering both EFN and trophobiotic insects. Although ants did not directly affect pollinator behaviour, leaf herbivory in plants hosting treehoppers indirectly influenced pollination by reducing both visit duration and frequency.

New host records of Aglaomelissa duckei and a compilation of host associations of Ericrocidini bees (Hymenoptera: Apidae)

open access: yesZoologia (Curitiba), 2009
For the first time, confirmed host records are reported for the monotypic Ericrocidini genus Aglaomelissa Snelling & Brooks, 1985. Aglaomelissa duckei (Friese, 1906) emerged from trap-nests of Centris (Heterocentris) analis (Fabricius, 1804) and C ...
