13. 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

14. Pollination efficiency on Ipomoea bahiensis (Convolvulaceae): morphological and behavioural aspects of floral visitors
ABSTRACT: Pollination depends on morphological and behavioural adjustments between visitors and plants. Some plant species as Ipomoea bahiensis (Convolvulaceae) provide nectar and pollen to visitors and occur in anthropic areas, therefore becoming an important source of resources for the maintenance of native pollinating insects. However, what is the efficie

15. Performance of two honey bee subspecies during harsh weather and Acacia gerrardii nectar-rich flow
ABSTRACT Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic subtropical weather conditions on the performance of honey bee colonies. This study investigated

16. 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

17. The efficiency of bees in pollinating ephemeral flowers of Jacquemontia bracteosa (Convolvulaceae)
ABSTRACT The family Convolvulaceae is widely distributed in tropical regions, mainly in open areas. Convolvulaceae flowers are characterized mainly by being beautiful and ephemeral, attracting many flower visitors that belong to different taxonomic groups. This work aimed to investigate the interactions between insects and flowers of Jacquemontia bracteosa (

18. Bee assemblage in habitats associated with Brassica napus L.
ABSTRACTAssessments in agricultural crops indicate that alterations in the landscape adjacent to the crops can result in reduced productivity due to loss or low abundance of pollinating agents. In the canola crop, production is partially dependent on insect pollination. Therefore, knowledge of the faunal diversity within and near crop fields is key for the m

19. Fruit set of distylous Psychotria carthagenensis Jacq. (Rubiaceae) mediated by Apis mellifera (Apidae) and species of Augochloropsis (Halictidae)
Heterostyly is a floral polymorphism consisting in the presence of two morphs in the population that differ reciprocally in the position of their sexual organs. Heterostylous species depend on visitors to produce fruits, but the efficiency of insect species as pollinators greatly varies and depends on the morph visited. The aim of the present study was to de

20. Pollen types used by Centris (Hemisiella) tarsata Smith (1874) (Hymenoptera, Apidae) in the provisioning of brood cells in an area of Caatinga
The aim of this study was to identify, by sediment pollen analysis, the plant species used as floral resources for the provisioning of brood cells in Centris (Hemisiella) tarsata, in an area of Caatinga, within the municipality of Nova Soure, Bahia State, Brazil. The analysis of pollen contents from three brood cells revealed 11 pollen types, corresponding t

21. Baru: biologia e uso.
ABSTRACT: Dipteryx alata Vog. is a native leguminous tree species from Cerrado, the Brazilian Savannah. It is widespread and plays an important role as key species for environmental conservation as well as for rural families to get additional income by exploiting its seeds. Its wood, which is quite durable, is used for several applications in the farm; the c

23. Análise quantitativa de células digestivas e regenerativas do intestino médio de Melipona quadrifasciata anthidioides (Hymenoptera; Apidae) / Quantitative analysis of digestive and regenerative cells of the midgut of Melipona quadrifasciata anthidioides (Hymenoptera; Apidae)
Bees have economic importance for their role as crops pollinators, production of honey, wax and propolis. The stingless bees (tribe Meliponini) are specific pollinators of many native plant species, most notably the species Melipona quadrifasciata anthidioides (Kerr et al., 1996). Thus, a deeper understanding of the biology of this species may facilitate a b

24. Mel de abelhas nativas e africanizadas do estado de Alagoas : composição química, segurança microbiológica e atividade terapêutica. / Honey of beens native and africanized state of Alagoas State : chemical composition,security microbiological and activity therapy.
The rational development of bees is one of the most promising agricultural activities, since it is essentially self-sustaining family and therefore helps to maintain and restore the environment, through their role in pollination, and guarantee income to the producer who employs his family on it. Honey is the main product of this activity, being generated by
