The evolution of haploid chromosome numbers in Meliponini.

open access: yesPLoS ONE, 2019
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 ...

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]

open access: yesEcol Evol
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]

open access: yesApidologie, 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

Exocrine glands of Schwarziana quadripunctata (Hymenoptera, Apinae, Meliponini) [PDF]

open access: yesBrazilian Journal of Biology, 2001
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]

open access: yesEcol Evol
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]

open access: yesHereditas, 2003
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

open access: yesAnnual Review of Entomology, 2023
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.
