Diversity of Wild Bees along Elevational Gradient in an Agricultural Area in Central Java, Indonesia

open access: yesPsyche: A Journal of Entomology, Volume 2017, Issue 1, 2017., 2017
Increases in mean temperature affect the diversity and abundance of wild bees in agricultural ecosystems. Pollinator community composition is expected to change along an elevational gradient due to differences in the daily ambient temperature. This study investigated the diversity and abundance of wild bees in an agricultural area along an elevational ...

Host‐Cleptoparasite Biogeographical Congruence Through Time: The Case of Cuckoo Oil Bees

open access: yesJournal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim Insect brood parasites (i.e., cleptoparasites), like cuckoo bees, typically attack hosts within specific lineages, but seem to be less constrained by the biogeographical movements of their hosts compared to obligate parasites. Cuckoo bees depend on stable host populations, being particularly sensitive to environmental changes and thus ...

Antioxidant Activity of a Geopropolis from Northeast Brazil: Chemical Characterization and Likely Botanical Origin

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017
Geopropolis is a product containing wax, plant resin, and soil particles. It is elaborated by stingless bees of tribe Meliponini. Methanol extracts of sample of geopropolis produced by Scaptotrigona postica (“mandaguari”) in the state of Rio Grande do Norte (RN, northeast Brazil) were analyzed for the determination of standard parameters (total phenols,

Meliponini neotropicais: o gênero camargoia moure, 1989 (apinae, apidae, hymenoptera)

open access: yesArquivos de Zoologia, 1996
Camargoia nordestina, sp. n., is described from the dry valleys of Piaui state, NE Brazil. It differs from C. camargoi by the yellow maculations ofparaocular areas ending at the level of superior tangent of antennal sockets, basitarsi II and tibiae and basitarsi III blackish, microtrichiae of anterior wing uniformly fuscous and the median ocellus above

Floral Resources Partitioning by Two Co-occurring Eusocial Bees in an Afromontane Landscape

open access: yesSociobiology, 2018
Floral preferences of generalist foragers such as eusocial bees influence the success of pollination of many flowering plants, as well as competition with many other bee species in tropical communities.

Ultraconserved element (UCE) phylogenomics illuminates the evolutionary history and biogeography of Dorymyrmex pyramid ants

open access: yesSystematic Entomology, Volume 50, Issue 2, Page 325-348, April 2025.
A newly expanded UCE phylogeny of Dorymyrmex robustly confirms the major lineages and recommends a new scheme of four major species groups. The asymmetrical, amphitropical distribution of Dorymyrmex was likely created by a single dispersal event across the Isthmus of Panama before the traditional closure date of 3 Mya.

First records of four orchid bee species (Hymenoptera, Apidae: Euglossini) in Ecuador [PDF]

open access: yesJournal of Insect Biodiversity and Systematics
Orchid bees (Hymenoptera, Apidae, Euglossini) play a vital role as key pollinators in the Neotropical forests. Their preference for forested areas makes these bees more susceptible to environmental changes, particularly in areas under severe human impact,

A comparative study of the proventricular structure in corbiculate apinae (Hymenoptera, Apidae)

open access: yesMicron, 2001
The present study compares the proventricular structure, analyzed under scanning electronic microscope (SEM), among tribes of corbiculate Apinae. Fifty-one species of stingless bees (Meliponini), one species of honeybee (Apini), three species of bumblebees (Bombini) and seven species of orchid bees (Euglossini), were analyzed as in-group, and one ...
