“…Most bees rely on pollen as the main source of nitrogen and it is collected mainly to feed the larvae [3]. In A. mellifera, the quantity of brood and stored pollen influences the pollen foraging [37].…”

Colonies of the Brazilian stingless bee Plebeia remota show a reproductive diapause in autumn and winter. Therefore, they present two distinct reproductive states, during which colony needs are putatively different. Consequently, foraging should be adapted to the different needs. We recorded the foraging activity of two colonies for 30 days in both phases. Indeed, it presented different patterns during the two phases. In the reproductive diapause, the resource predominantly collected by the foragers was nectar. The majority of the bees were nectar foragers, and the peak of collecting activity occurred around noon. Instead, in the reproductive phase, the predominantly collected resource was pollen, and the peak of activity occurred around 10:00 am. Although the majority of the foragers were not specialized in this phase, there were a larger number of pollen foragers compared to the phase of reproductive diapause. The temperature and relative humidity also influenced the foraging activity.

“…Most of these materials have vegetal origin, as pollen, nectar, resin, latex, leaves, trichomes, fragrances, oils, seeds, and so forth. In addition, stingless bees also collect materials of other origins, as animal feces, clay, water, and fungi spores, for example [1][2][3].…”

“…Muitos destes microrganismos naturalmente associados às abelhas representam uma microflora não patogênica (GILLIAM, 1997), sendo muitos ainda desconhecidos. Eltz et al (2002), citando diversos autores, informam que a coleta de fungos por abelhas em substituição ao pólen já foi verificada para espécies dos gêneros Apis, Trigona e Partamona. Teixeira et al (2003) descreveram uma espécie de levedura isolada em abelhas…”

IntroduçãoO mel, juntamente com os demais produtos das abelhas, está associado a uma imagem de produto natural, saudável e limpo (BOGDANOV, 2006), sendo atribuídas a ele propriedades medicinais e atividade antimicrobiana, geralmente relacionadas às suas características físicas e químicas (MOLAN, 1999).A despeito destas características ainda é possível observar a ocorrência de diversos microrganismos no mel, que se constituem em um dos principais critérios de qualidade do produto, juntamente com as suas características sensoriais, químicas e físicas. Internacionalmente, estes critérios de qualidade são especificados em regulamentos, compilados no Codex Alimentarius (BOGDANOV et al., 1999). Apesar da atual legislação brasileira para mel (BRASIL, 2000) não contemplar as características microbiológicas aceitáveis para o produto, estes conceitos precisam ser revistos principalmente por se tratar de um produto consumido por crianças, idosos, gestantes e doentes (TCHOUMBOUE et al., 2007), sendo os únicos valores de referência estabelecidos pela RDC 012 da ANVISA (BRASIL, 2001) e constituindo na contagem de bolores e leveduras, e verificação da presença de coliformes a 35 °C e coliformes a 45 °C.Importante ressaltar que todas estas regulamentações que visam ao controle de qualidade do mel, seja nacional ou internacional, consideram características de qualidade AbstractHoney is a product that presents antimicrobial activity attributed to physical and chemical factors. Even so, it is still possible to find many microorganisms present in this product, which can be used as quality indicators. The objective of this work was to evaluate the microbiologic quality of the honey produced by stingless bee species from the State of Bahia, Brazil. Fourteen samples of honey were evaluated for the moisture content, water activity, standard counting of moulds and yeasts, and presence of microorganisms of coliform group. A total of 50.0% of the samples presented standard counting of moulds and yeasts above the maximum value permmited by the Brazilian food legislation. This disqualification of samples asseptically harvested indicates the need of identification of this microbiota and its possible natural occurrence in the honey produced by this group of bees. None of the samples was disqualified regarding the counting of microorganisms of the coliform group.

ResumoO mel é um produto que apresenta atividade antimicrobiana atribuída a fatores físicos e químicos. Mesmo assim, ainda é possível encontrar uma série de microrganismos presentes neste produto e que servem como indicadores de qualidade. O objetivo deste trabalho foi avaliar a qualidade microbiológica do mel produzido por espécies de abelhas sem ferrão (Trigonini) do Estado da Bahia. Quatorze amostras de mel foram avaliadas quanto ao teor de umidade, atividade de água, contagem padrão de bolores e leveduras, e presença de microrganismos do grupo coliforme. Um total de 50,0% ...

“…Stingless bees of the genus Trigona are highly social and live in perennial colonies with up to several thousand individuals (Wille, 1983;Roubik, 1989Roubik, , 1993. As in honeybees, their principal resources are pollen and nectar, but they also collect materials such as resin, water, sap, wax, honeydew, extrafloral nectar, mud, salts, animal protein, and fungal spores for nutrition or nest-building materials (Roubik, 1989;Eltz et al, 2002). Pollen is the sole resource collected on many flowers (Roubik, 1989).…”

Foraging loads of stingless bees and utilisation of stored nectar for pollen harvesting

-We compared nectar, pollen and resin loads of individual workers among colonies from six Trigona species in Sabah, Borneo. Individual bees rarely collected large amounts of both nectar and pollen during the same foraging trip. Instead, comparison of crop contents across departing, flower-visiting, and returning bees suggests that pollen-collecting workers often carried highly concentrated nectar in their crop upon nest departure. During their foraging trip, this crop nectar volume decreased progressively until crops were largely empty when they returned to their nest. Individually marked pollen foragers carried highly concentrated nectar when they left their nest, while crops and corbiculae from marked nectar foragers were empty upon departure. We suggest that a large proportion of previously stored and highly concentrated nectar may be required for pollen adhesion to corbiculae and/or serve as fuel during foraging on nectarpoor flowers.foraging behaviour / nectar / pollen load / resin / Trigona
