13. Viruses that affect Apis mellifera and their occurrence in Brazil
RESUMO: As abelhas são insetos de grande importância na agricultura, cumprindo um papel muito importante na polinização e na renovação do ecossistema. No entanto, em diversos países têm sido relatadas perdas significativas de colônias e declínio da população de abelhas melíferas e nativas, nos últimos anos. Com isso, surgiram novos estudos sob

14. Bees Diversity on Flowers of Eremanthus spp. (Asteraceae)
ABSTRACT Bees are considered important pollinators due to their fidelity to plants, enabling the maintenance of gene flow between plant species. The objective of this study was to recognize the visit of bees in two Candeia species, Eremanthus erythropappus and Eremanthus incanus (Asteraceae), as well as to analyze the pollen content carried by bees in a rege

15. Partial characterization of ethanolic extract of Melipona beecheii propolis and in vitro evaluation of its antifungal activity
ABSTRACT The ethanolic extract of Melipona beecheii Bennett 1831, propolis from Yucatán Mexico was evaluated in vitro for the determination of its phenolic compound content, antioxidant capacity and antifungal activity. The results were compared against those of the ethanolic extract of Apis mellifera propolis. The total phenolic content, flavonoid content

16. Chemical characterization, antioxidant and anti-HIV activities of a Brazilian propolis from Ceará state
ABSTRACT Propolis (bee glue) a product of Apis mellifera L. is a resinous mixture containing chiefly beeswax and resin harvested by bees from plant leaves, buds and exudates. Extracts of a propolis sample from Salitre, a municipality of Ceará state (northeast Brazil) were obtained with solvents of increasing polarity (hexane, chloroform, ethyl acetate and m

17. An effective and economic method to produce re-ripe honey with honeybee colonies
Abstract Beekeepers who manage migratory beekeeping in China preferred to produce non-ripe honey rather than natural ripe honey in short flowering seasons, to obtain higher honey yield and profits. To explore an alternative method for production of ripe honey, we fed Apis cerana cerana colonies with non-ripe honey produced from Apis mellifera ligustica colon

18. Bioactivity and action mechanism of green propolis against Pythium aphanidermatum
Abstract: We have established how natural compounds from green propolis collected by the species Apis mellifera act against the growth of Pythium aphanidermatum. On the basis of mass spectrometry (Q-ToF MS), we determined that Artepillin C, the major constituent of green propolis, underlies the effect and displays activity against P. aphanidermatum at a mini

19. Royal jelly production in Africanized colonies with selected queens, use of Chinese model cups and supplementation
ABSTRACT. This research was carried out to evaluate the royal jelly production in two trials. In Trial I, three genotypes of Africanized honeybees (Apis mellifera L.) were submitted to royal jelly production with two types of cups of different size and volume (conventional and Chinese model) and two types of supplements (commercial and formulated). A total o

20. COMPOSIÇÃO QUÍMICA, ATIVIDADE ANTIRADICALAR E ANTIMICROBIANA DO PÓLEN APÍCOLA DE FABACEAE
The aim of this investigation was to analyze two samples of pollen collected by Apis mellifera bees in view of their chemical composition, antiradicalar and antimicrobial activities. Palynological analysis showed that the predominant pollen was Fabaceae species (42.3%, sample I and 50.6%, sample II). The characterization by ultra-performance liquid chromatog

21. AVALIAÇÃO DA QUALIDADE DE MÉIS DE ABELHAS AFRICANIZADAS E SEM FERRÃO NATIVAS DO NORDESTE DO ESTADO DO PARÁ
Resumo O objetivo do trabalho foi avaliar a qualidade microbiológica e físico-química do mel in natura (np) e pasteurizado (p) de abelhas africanizadas (Apis mellifera) e de duas espécies de abelhas sem ferrão (Melipona fasciculata e Melipona flavolineata) nativas da região Nordeste do Estado do Pará. As análises físico-químicas foram realizadas de

22. Análise dos efeitos de variáveis climáticas no desempenho de forrageamento de pólen de abelhas Apis mellifera
RESUMO Serviços de polinização são essenciais para a reprodução de uma grande parte das plantas com flores. Além de fundamental para produtividade agrícola e segurança alimentar no planeta, a atividade de polinização por Apis mellifera também possibilita a produção do pólen apícola. Devido a sua riqueza nutricional, o pólen apícola vem send

24. Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)?
ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors
