The Waggle Dance as an Intended Flight: A Cognitive Perspective [PDF]

, 2019
The notion of the waggle dance simulating a flight towards a goal in a walking pattern has been proposed in the context of evolutionary considerations. Behavioral components, like its arousing effect on the social community, the attention of hive mates ...

Substituição natural de rainhas fisogástricas e distância de vôo dos machos em Tiuba (Melipona compressipes fasciculata Smith, 1854) e Uruçu (Melipona scutellaris Latreille, 1811) (Apidae, Meliponini) Natural substitutions of queens and flight distance of males in tiuba (Melipona compressipes fasciculata Smith, 1854) and uruçu (Melipona scutellaris Latreille, 1811) (Apidae, Meliponini)

Acta Amazonica, 2004
Este trabalho relata detalhes da vida reprodutiva de duas espécies de abelhas sem ferrão. Rainhas velhas de Melipona compressipes fasciculata, no Maranhão, morrem e são substituídas com sucesso em todos os meses. Rainhas de Melipona scutellaris, trazidas

Tragedy of the commons in Melipona bees [PDF]

, 2004
In human society selfish use of common resources can lead to disaster, a situation known as the ‘tragedy of the commons’ (TOC). Although a TOC is usually prevented by coercion, theory predicts that close kinship ties can also favour reduced ...

Toxicological assessments of agrochemical effects on stingless bees (Apidae, Meliponini)

MethodsX, 2020
Bee pollination is crucial for ecosystem maintenance and crop production. The ubiquity of bee pollinators in agricultural landscapes frequently results in their exposure to agrochemicals, which has been associated with their decline. Stingless bees are wild pollinators restricted to the Pantropical region, and like honey bees, are suffering colony ...

Class III glands in the abdomen of Meliponini [PDF]

Apidologie, 2006
Class III tegumentar glands were studied in workers, as well as in queens and males when available, of 56 Meliponini species. The presence and development of these glands varies widely among and within species. However, the queen typically has more glands than do workers, and males rarely have any. Gland development in workers was evaluated by counting

Are isomeric alkenes used in species recognition among neo-tropical stingless bees (Melipona spp) [PDF]

, 2017
The majority of our understanding of the role of cuticular hydrocarbons (CHC) in recognition is based largely on temperate ant species and honey bees. The stingless bees remain relatively poorly studied, despite being the largest group of eusocial bees ...

Geographic Range and Nest Architecture of Cephalotrigona Capitata Smith, 1854 (Apidae: Meliponini) in the State of Bahia, Northeastern Brazil

Journal of Apicultural Science, 2019
The bees of the genus Cephalotrigona (locally known as “mombucas”) play a key role in natural environments but their bioecological features, required to design proper management and conservation strategies, are scarce in most species.

Stingless bee floral visitation in the global tropics and subtropics

Global Ecology and Conservation, 2023
Bees play a key role in maintaining healthy terrestrial ecosystems by pollinating plants. Stingless bees (Apidae: Meliponini) are a diverse clade of social bees (>500 species) with a pantropical distribution spanning South and Central America, Africa ...

Hygienic behavior in Melipona quadrifasciata anthidioides (Apidae, Meliponini) [PDF]

Apidologie, 2017
Hygienic behavior in stingless bees is a trait of workers that confers colony-level resistance against some brood diseases. Workers of hygienic colonies detect, uncap and remove dead or diseased brood from the nest cells. We examined the hygienic behavior in stingless bees (Melipona quadrifasciata anthidioides) from freeze-killed brood assay using ...

Genome-wide discovery and characterization of microsatellite markers from Melipona fasciculata (Hymenoptera: Apidae), cross-amplification and a snapshot assessment of the genetic diversity in two stingless bee populations

European Journal of Entomology, 2018
Brazilian native meliponines are currently threatened by increased human impacts. The assessment of their genetic variation by microsatellite DNA markers can assist in the conservation of populations and help in the planning and establishment of ...
