13. Volatile compounds and palynological analysis from pollen pots of stingless bees from the mid-north region of Brazil
ABSTRACT Samburá is the botanical pollen nectar agglutinated by salivary secretions of bees. Stingless bee pollen samples were collected in three periods of the year in Monsenhor Gil town, PI, Brazil, for extraction of volatile constituents by different techniques, analyzed by gas chromatography-mass spectrometry (GC-MS) and the palynological analysis used

14. Ecuadorian honey types described by Kichwa community in Rio Chico, Pastaza province, Ecuador using Free-Choice Profiling
Abstract Pastaza is the largest and least populated province in Ecuador, with seven native indigenous nationalities. The Kichwas from the Rio Chico community live near to the capital city Puyo, are recognized for their knowledge on stingless honey bees. From the 400 species of Neotropical Meliponini that make honey in cerumen pots, almost 100 thrive in South

15. Epigenetic modifications and their relation to caste and sex determination and adult division of labor in the stingless bee Melipona scutellaris
Abstract Stingless bees of the genus Melipona, have long been considered an enigmatic case among social insects for their mode of caste determination, where in addition to larval food type and quantity, the genotype also has a saying, as proposed over 50 years ago by Warwick E. Kerr. Several attempts have since tried to test his Mendelian two-loci/two-allele

16. Screening for quality indicators and phenolic compounds of biotechnological interest in honey samples from six species of stingless bees (Hymenoptera: Apidae)
Abstract Honey from stingless bees of the genus Melipona is a well sought product. Nevertheless lack of legal frameworks for quality assessment complicates the evaluation of food safety and marketing of these products. Seeking to assess the quality of honey from the bees of this genus, physical and chemical analyses, identification of phenolic compounds, and

17. Bombus brasiliensis Lepeletier (Hymenoptera, Apidae) infected with Nosema ceranae (Microsporidia)
ABSTRACT Heavy infections caused by a microsporidium were detected in midgut epithelium cells of two adult workers of the bumble bee Bombus brasiliensis Lepeletier collected near Puerto Iguazú, Misiones province, Argentina. Microsporidium rRNA (16S small subunit) was amplified by 218MITOC primers and produced amplicons indicating presence of Nosema ceranae

18. Biological and therapeutic effects of honey produced by honey bees and stingless bees: a comparative review
ABSTRACT Honey is a natural product produced by both honey bees and stingless bees. Both types of honey contain unique and distinct types of phenolic and flavonoid compounds of variable biological and clinical importance. Honey is one of the most effective natural products used for wound healing. In this review, the traditional uses and clinical applications

19. Plectoplebeia, a new Neotropical genus of stingless bees (Hymenoptera: Apidae)
ABSTRACT A new stingless bee genus, Plectoplebeia gen. nov., is proposed to accommodate a peculiar Neotropical species currently placed in Plebeia Schwarz, 1938. The brief, but convoluted taxonomic history of its type species, Trigona nigrifacies Friese, 1900, is documented, with Trigona (Plebeia ) intermedia Wille, 1960 being placed as its junior synonym. P

20. In vitro alpha glucosidase inhibition and free-radical scavenging activity of propolis from Thai stingless bees in mangosteen orchard
ABSTRACTThe chemical component and biological activity of propolis depend on flora area of bee collection and bee species. In the study, the propolis from three stingless bee species, Lepidotrigona ventralis Smith, Lepidotrigona terminata Smith, and Tetragonula pagdeni Schwarz, was collected in the same region of mangosteen garden from Thailand. Total phenol

22. Removal of clay by stingless bees: load size and moisture selection
Alguns organismos têm custos energéticos associados com o transporte de recursos, que não necessariamente são alimentos. Algumas abelhas sem ferrão da Amazônia Central (Melipona flavolineata e M. lateralis) coletam argila na margem de córregos para a construção do ninho. A umidade da argila varia ao longo do barranco e as abelhas coletam argila de p

23. Handling sticky Resin by Stingless Bees: Adhesive Properties of Surface Structures
Muitas espécies das abelhas-sem-ferrão (Hymenoptera: Meliponini) como Tetragonisca angustula coletam resina para a defesa dos seus ninhos contra invasores como formigas ou abelhas cleptobióticas. Pequenas porções de resina são aderidas nos corpos e extremidades dos invasores causando a sua imobilização. Observa-se que a resina é removida com facilid

24. Insights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in sting
