13. CHEMICAL COMPOSITIONS AND ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF PROPOLIS PRODUCED BY Frieseomelitta longipes AND Apis mellifera BEES
In this study, we investigated the chemical compositions and antioxidant and antimicrobial activities of propolis produced by the stingless bee Frieseomelitta longipes and the honeybee Apis mellifera collected from colonies in North Brazil. In terms of volatile composition, both mono- and sesquiterpenes were detected in the propolis of F. longipes while only

14. 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

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. 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

17. 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

18. 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

19. Foraging pattern and harvesting of resources of subterranean stingless bee Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae: Meliponini)
RESUMO A atividade de vôo das abelhas é influenciada por fatores ambientais, como temperatura, umidade e intensidade luminosa; e pelas condições internas da colônia. Informações sobre a atividade externa das abelhas é de grande importância, pois proporciona dados importantes para o conhecimento da biologia das espécies, fornecendo subsídios para o

20. New species of the stingless bee genus Schwarziana (Hymenoptera, Apidae)
ABSTRACT Two new species of the stingless bee genus Schwarziana from Brazil are described and illustrated. Schwarziana bocainensis sp. nov. is described from Serra da Bocaina, in São Paulo, and S. chapadensis sp. nov. is described from Chapada dos Veadeiros, in Goiás. An identification key to workers of the known species of Schwarziana is provided.

21. 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. Propolins and glyasperin A from stingless bee nests
Abstract Chemical investigation of the dichloromethane extracts of the propolis collected from bee (Tetragonula biroi Friese) hives in San Roque, Sorsogon, Philippines afforded propolin A (1), propolin E (2), propolin H (3), glyasperin A (4), squalene, a mixture of lupeol, α-amyrin and β-amyrin, and another mixture of urs-12-en-3-one, olean-12-en-3-one and

23. Molecular genetic diversity in populations of the stingless bee Plebeia remota: A case study
Genetic diversity is a major component of the biological diversity of an ecosystem. The survival of a population may be seriously threatened if its genetic diversity values are low. In this work, we measured the genetic diversity of the stingless bee Plebeia remota based on molecular data obtained by analyzing 15 microsatellite loci and sequencing two mitoch

24. Very low mitochondrial variability in a stingless bee endemic to cerrado
Partamona mulata is a stingless bee species endemic to cerrado, a severely threatened phytogeographical domain. Clearing for pasture without proper soil treatment in the cerrado facilitates the proliferation of termite ground nests, which are the nesting sites for P. mulata. The genetic consequences of these changes in the cerrado environment for bee populat
