Richness of Wild Bees (Hymenoptera: Apidae) in a Forest Remnant in a Transition Region of Eastern Amazonia

Psyche: A Journal of Entomology, Volume 2019, Issue 1, 2019., 2019
Eastern Amazonia is an area with great biological diversity that has suffered rapid deforestation and forest fragmentation over the years. Because of the scarcity of data on the fauna and flora, the northwest of the state of Maranhão has become a priority area for studies that seek to gain a better understanding of bee fauna.

Buzzing Wild Bee Visits Enhance Seed Set in Eggplant, Solanum melongena

Psyche: A Journal of Entomology, Volume 2017, Issue 1, 2017., 2017
Sixty percent of the angiosperms with poricidal anthers are buzz‐pollinated by bees (Hymenoptera: Apoidea: Apiformes). Plant taxa with Solanum‐type flowers have larger anthers and shorter filaments. Solanum melongena (Solanaceae) is more commonly and efficiently pollinated by buzz pollinators. The present study documented bees and their diurnal pattern

Generalist Bee Species on Brazilian Bee‐Plant Interaction Networks

Psyche: 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 ...

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, Volume 2026, Issue 6, June 2026.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

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

Revista 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 ...

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

Ecological 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.

Corrigendum to "Bee systematics and conservation"

Sociobiology
In the published article, Figure 2 was incorrect because the geographic areas of three taxa were shown with errors: the Allodapini (Apidae) occur in the Afrotropical, Australian, Oriental, and Palearctic regions; the Centridini (Apidae) occur in the ...
