Investigating Eusociality in Bees while Trusting the Uncertainty
Sociobiology, 2014 Phylogenetic hypotheses and estimates of divergence times have already been used to investigate the evolution of social behavior in all lineages of bees. The interpretation of the number of origins of eusocial behavior and the timing these events depends

Genetic breeding on the bee Melipona scutellaris (Apidae, Meliponinae) [PDF]
Acta Amazonica, 2006 A selection of queens of Melipona scutellaris through the most productive colonies were carried out during eight months in an orange honeyflow. Each of the colonies was evaluated by its production, that is, the gross weight production ( pollen, brood, geopropolis and wax of each hive).

EFFECTS OF BIOPESTICIDES IN Tetragonisca angustula LATREILLE (HYMENOPTERA: MELIPONINAE) POLLINATORS
Arquivos de Ciências Veterinárias e Zoologia da UNIPAR, 2020 Stingless bees Tetragonisca angustula (Latreille) (Hymenoptera: Meliponinae) are pollinators of native and cultivated plants, are therefore in contact with areas contaminated by pesticides. These native bees were evaluated for changes in gene expression of esterase isoenzymes and peptides after contamination by contact with insecticides growth ...

Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae). [PDF]
, 2017 Despite the fact that Meliponini bee lost their sting apparatus (stingless bees), they did not lose their ability to defend themselves. A variety of defensive strategies is described for the group, such as bitting and resin deposition.

Labor division in Melipona compressipes fasciculata Smith (Hymenoptera: Apidae: Meliponinae) [PDF]
Anais da Sociedade Entomológica do Brasil, 1997 Labor division in the stingless bee Melipona compressipes fasciculata Smith was analyzed and compared with that of other eusocial bees Meliponini and Trigonini. The results showed a sequence of activities which was similar to that of other stingless bees already studied, such as: grooming; cerumen work; cell construction; cleaning; the colony ...

Wax chemistry of two stingless bees of the Trigonisca group (Apididae: Meliponinae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985 1. 1. The wax of Trigona (Trigonisca) buyssoni and T. (T.) atomaria is much simplier in composition than that of Apis mellifera and consists of hydrocarbon (59.3 ± 3.5% and 70.9 ± 6.3%, respectively, by wt), wax monoester (26.8 ± 3.5% and 25.5 ± 6.3%), free fatty acid (5.4 ± 1.6% and 1.7 ± 0.9%), primary alcohol (7.0 ± 2.4 and 1.0 ± 0.9%), and ...
