“…This finding corroborates previous palynological studies performed in areas of the C e n t r a l Am a z o n i nv o l v i n g s p e c i e s o f Frieseomelitta , Melipona , Scaptotrigona , and Trigona (Marques- Souza et al 1996Souza et al , 2002Marques-Souza 2010). In areas of caatinga in the northeast region of Brazil, a similar pattern was also observed in palynological works with species of Melipona , Scaptotrigona , and Tetragonisca (Alves et al 2006;Novais et al 2006;Santana et al 2011).…”

-Tetragonisca angustula is a stingless bee species widely distributed in Brazil. Past studies have shown a rich native flora supplying this meliponine with pollen and nectar. The aim of this study was to compare the food provisions of T. angustula in two areas in the Lower Amazon mesoregion in the state of Pará and two areas of caatinga vegetation in the state of Bahia, Brazil. We used a published data set of 57 samples of honey and 46 samples of pollen stored in colonies of T. angustula . The honeys from the Lower Amazon and from the caatinga displayed 23 and 16 pollen types with frequency higher than >10 %, respectively, with emphasis on the families Fabaceae, Solanaceae, and Urticaceae. In the pollen stored samples, 18 and 11 pollen types were found, respectively. Cluster analyses (Dice similarity) performed with these published pollen spectra of the honeys grouped the samples from each geographic region with higher similarity than the analyses performed with the pollen spectra of the stored pollen.cluster analysis / Dice similarity / entomopalynology / honey / melissopalynology / pollen stored / stingless bees

“…Overall, the Melastomataceae family was the most representative in terms of pollen types. Melastomataceae is widely distributed in the region and is well represented in numerous studies of stingless bees in the Amazon (Marques-Souza et al 1995;Marques-Souza 1996;Marques-Souza et al 1996;Marques-Souza et al 2002;Oliveira et al 2009). …”

“…However, a number of studies have evaluated pollen collected by stingless bees in the central Amazon region. Those studies have involved the use of classical protocols for the collection of pollen foraged by bees, such from pollen pots (Absy et al 1984;Rech & Absy 2011a;Rech & Absy 2011b), from nectar and honey samples (Absy et al 1980) or, more commonly, from the pollen baskets of worker bees (Absy & Kerr 1977;Marques-Souza et al 1995;Marques-Souza 1996;Marques-Souza et al 1996;Marques-Souza et al 2002;Oliveira et al 2009). In this context, palynology has become an important tool, supporting the processes related to the analysis and identification of pollen grains.…”

We applied an "adapted" protocol for collecting and processing pollen grains in the pollen analysis of the post-emergence residue of Melipona (Melikerria) interrupta Latreille. The study was conducted at the Sant' Ana honey farm, located on the banks of the Solimões River, in the municipality of Manacapuru, in the state of Amazonas, Brazil, where a colony was monitored in October and November 2010. From that colony, 10 samples of post-emergence residue were collected. Unlike in the acetolysis method, there was no need to expose pollen grains to an acidic medium, because pollen loses its content during the larval digestive process. We identified 32 pollen types, from 19 botanical families, plus three undetermined pollen types. The most representative family was Fabaceae (Mimosoideae), with eight pollen types, Mimosa guilandinae being the most common species. Only the pollen of Miconia (Melastomataceae), with 74.10%, was classified as a common pollen. We also found that the pollen of Mimosa pudica (Fabaceae: Mimosoideae) retained its content, indicating that not all resources furnished by workers are utilized by the larvae. The protocol applied here, despite omitting the acetolysis process, was efficient, providing full details of pollen contained in post-emergence residue.

“…No que diz respeito à ornamentação da parede polínica, a escolha foi generalizada, porém com maior número de grãos de pólen com superfície psilada. Marques-Souza et al (2002) trabalhando com espécies de abelhas nativas da Amazônia Central, não encontraram evidência de que as características morfológicas do pólen (tamanho, forma e ornamentação) estivessem influenciando as coletas das abelhas estudadas.…”

ABSTRACT. Pollen harvest by Scaptotrigona depilis (Moure) (Hymenoptera, Meliponini) in Dourados, Mato Grosso do Sul, Brazil. Pollen harvest by workers of Scaptotrigona depilis (Moure, 1942) were identified in the region of Dourados, Mato Grosso do Sul, during the period of September, 2006 to August, 2007. From the 42 pollen types collected, the more representative ones during this period were those from the Myrtaceae (Eucalyptus spp.) and Mimosaceae family. The peaks for the values of the trophic niche breadth (H') in September (2.32), November (2.29) and October (2.02) showed that these bees can be generalist, depending upon availabilities and characteristics of flower sources. The values for equitability (J') also showed more uniform use of pollen sources during these months. The meteorological features (temperature, relative humidity and rainfall) did not show a direct relation to equitability and niche breadth. Equitability and niche breadth seem to be more related to the daily or seasonal cycles of pollen and nectar production.KEYWORDS. Diversity; floral resource; pollination; stingless bees. A crescente devastação de habitats naturais tem aumentado a preocupação dos especialistas com os possíveis efeitos sobre as populações de abelhas nativas e, consequentemente, com o desenvolvimento de estratégias para a sua preservação (Matheson et al. 1996). Segundo Kerr et al. (1999) o Brasil possui a maior diversidade de abelhas sem ferrão do mundo, podendo representar 90% dos polinizadores de um ecossistema, sendo assim, a preservação dos meliponíneos é também uma garantia de manutenção da base da cadeia alimentar. Além da manutenção da diversidade florística dos ecossistemas, um efeito direto da polinização por abelhas pode ser visto no aumento da produtividade de plantas cultivadas, através da introdução de ninhos em áreas agrícolas (Roubik 1995). RESUMO. Pólen coletado porAs relações dos meliponineos com as flores podem ser analisadas de maneira indireta e prática através da análise polínica do alimento transportado pelas campeiras para as colônias. E essa abordagem permite estimar o espectro de fontes florais e sua atratividade relativa sobre as colônias, em dado período ou hábitat (Imperatriz-Fonseca et al. 1993).De acordo com Ramalho et al. (2007), o hábito generalista em meliponíneos é considerado uma necessidade básica e, portanto, aceito como padrão entre essas abelhas eusociais da família Apidae, com grandes colônias perenes, altas taxas de produção de prole e que precisam de muito alimento ao longo de todo ano.No Mato Grosso do Sul são poucos os estudos do hábito alimentar das abelhas, com uso de grãos de pólen. Sendo a região de Dourados caracterizada por áreas cultivadas extensivas, sofrendo inúmeras perturbações ambientais que causam grande decréscimo nos recursos florais nativos, tornase importante conhecer os nichos tróficos dos polinizadores locais, com especial atenção às abelhas nativas para entender como elas estão respondendo a essas mudanças.Este trabalho teve como objetivo, identificar as fon...
