New occurrence of B chromosomes in Partamona helleri (Friese, 1900) (Hymenoptera, Meliponini) [PDF]

open access: yesGenetics and Molecular Biology, 2009
Cytogenetic analyses of the stingless bee Partamona helleri collected in the state of Bahia, Northeast Brazil revealed the chromosome numbers n = 18 in the haploid males and 2n = 35 in the diploid females. All karyotypes displayed one large acrocentric B chromosome, which differs from the minute B chromosomes previously described in the populations ...

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.

Thermal Tolerance in the Cellophane Bee Colletes inaequalis Reflects Early Spring Adaptation and Is Independent of Body Size and Sex

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
The cellophane bee, Colletes inaequalis, is a ground‐nesting, solitary species and key pollinator of spring plants. Our study shows it is thermally adapted to early spring conditions, with similar thermal traits in males and females despite differences in body size and emergence timing.

Queen turnover, nest usurpation and colony mortality in wild nests of the stingless bees Tetragonula carbonaria and Tetragonula hockingsi (Hymenoptera: Apidae)

open access: yesAustral Entomology, Volume 64, Issue 3, August 2025.
Abstract Social bees of the tribe Meliponini (stingless bees) are used as managed pollinators of crops throughout the world's tropical and subtropical regions. On Australia's East Coast, two native species—Tetragonula carbonaria and Tetragonula hockingsi—are the most widely propagated in hives, but knowledge of their biology and ecology in natural ...

Wasps Beyond Bees: Crop Species of Spondias (Anacardiaceae) Vary in Floral Scent and Attract Different Pollinator Taxa

open access: yesJournal of Applied Entomology, Volume 149, Issue 7, Page 1070-1083, August 2025.
ABSTRACT Spondias species are increasingly valued for their fruit production, which relies heavily on insect pollination. The flowers of these species are generalised, attracting a diverse array of insect visitors, including bees, beetles, flies, wasps and butterflies.

Meliponini and Apini in Africa (Apidae: Apinae): a review on the challenges and stakes bound to their diversity and their distribution

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2015
Introduction. Meliponini and Apini contribute to the pollination of flowering plants and to improving agricultural yields. These bees' diversity, distribution and abundance depend on the ecosystem in which they evolve.
