The evolution of haploid chromosome numbers in Meliponini.
It is thought that two evolutionary mechanisms gave rise to chromosomal variation in bees: the first one points to polyploidy as the main cause of chromosomal evolution, while the second, Minimum Interaction Theory (MIT), is more frequently used to ...

Overview of Stingless Bees in Brazil (Hymenoptera: Apidae: Meliponini)
Species richness of stingless bees (Hymenoptera: Apidae: Meliponini) was organized and updated from previously published data. From this research, we found 28 genera with 259 valid species and 62 undescribed species, in addition, brief comments on the ...

Harvesting the Casualties of War: <i>Macrogerodonia peruviana</i> Rove Beetles Prey Exclusively Upon Wounded <i>Trigona</i> spp. Stingless Bees (Coleoptera: Staphylinidae; Hymenoptera: Apidae). [PDF]
We report a previously undescribed trophic interaction in which Macrogerodonia peruviana rove beetles prey exclusively on wounded or recently killed Trigona stingless bees generated during aggressive conflicts at carrion. Field observations and choice experiments showed that beetles selectively targeted injured Trigona while ignoring carrion and other ...

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

Exocrine glands of Schwarziana quadripunctata (Hymenoptera, Apinae, Meliponini) [PDF]
This article describes the location, anatomy, histology and ontogeny of adult Schwarziana quadripunctata exocrine glands. These glands appear either as individualized organs (salivary gland system and Dufour gland) or as epidermis differentiation (tegumentary glands).

Pollen Exposed to Aerial Pesticide Spray Is a Major Exposure Pathway for Stingless Bees [PDF]
We conducted a molecular ecology experiment to determine foraging of stingless bees and potential exposure routes for aerially applied pesticides. We found that 27% of forager bees brought back Bti to the hive, and that this is a major route for pesticide exposure.

Longitudinal differentiation in Melipona mandacaia (Hymenoptera, Meliponini) chromosomes [PDF]
Melipona mandacaia is a stingless bee endemic to northeast Brasil. We describe the M. mandacaia karyotype using C-banding technique. fluorochrome staining and treatment with restriction enzymes and discuss the position of this species in the context of the phylogeny of the genus. Melipona mandacaia has 2n = 18 (14 SM + 2 M + 2 A).

Stingless Bee (Apidae: Apinae: Meliponini) Ecology
Stingless bees form perennial colonies of honey-making insects. The >600 species of stingless bees, mainly Neotropical, live throughout tropical latitudes. Foragers influence floral biology, plant reproduction, microbe dispersal, and diverse ecosystem functions.
