Defensive repertoire of the stingless bee Melipona flavolineata Friese (Hymenoptera: Apidae). [PDF]
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.

Phylogenomics Controlling for Base Compositional Bias Reveals a Single Origin of Eusociality in Corbiculate Bees. [PDF]
As increasingly large molecular data sets are collected for phylogenomics, the conflicting phylogenetic signal among gene trees poses challenges to resolve some difficult nodes of the Tree of Life.

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

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

Age polyethism in Plebeia emerina (Friese) (Hymenoptera: Apidae) colonies related to propolis handling [PDF]
Stingless bees collect plant resins and make it into propolis, although they have a wider range of use for this material than do honey bees (Apis spp.). Plebeia spp.

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

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.

DNA Barcoding applied to the identification of Meliponini in the Lençóis Maranhenses microregion, Brazil [PDF]
Stingless bees (Meliponini) are essential pollinators widely distributed in tropical regions, playing a crucial role in ecosystem maintenance. In Brazil, they are found throughout the national territory. DNA barcoding has emerged as an effective tool for
