“…This could be explained by the fact that pollen types with low collection concentration would serve as a secondary resource with little appeal. This pollen types can, eventually serve as a complement to the colony food needs and becomes important for maintaining their balance, for short periods, when the resources supply is subject to seasonal variations (Modro et al 2011).…”

We aimed to evaluate the frequency of bee pollen production, its botanical origin and chemical composition when collected in different seasons. Our results indicate that higher proteins (22.80 ± 3.09%) and flavonoids (2789.87 ± 1396.00 μg 100g -1 ) levels were obtained in the winter season, which also showed greater pollen production (134.50 ± 35.70 grams) and predominance of the Myrtaceae family. As for spring we found high concentrations of lipids (4.62 ± 2.26%) and low ash content (2.22 ± 0.39%). Regarding the amino acid composition and vitamin C content, we found no differences between the averages throughout the seasons. Our results highlight the importance of understanding not only the botanical origin and the chemical composition of bee pollen, but also the harvesting frequency of this product by bees, so that it becomes possible to supplement the colonies in times of natural food resources shortage.

“…Although the results show that M. grandis prefers some plant species to collect floral resources, Ramalho et al (1985), Velthus (1992), Modro et al (2011) report that pollen types with (FO) below < 10 % can be considered secondary resources, being used as a food supplement when there are fewer species in flowering. This way M. grandis would increase or decrease its trophic niche according to the flowering intensity.…”

TROPHIC RESOURCES COLLECTED BY Melipona grandis GUÉRIN, 1844 (APIDAE: MELIPONINA) IN RURAL AREA OF RIO BRANCO, ACRE – BRAZIL

et al. 2020

Melipona grandis has a wide geographic distribution in Latin America. Moreover, it is a species used in honey production by native meliponicultors of Acre. This study aimed to identify plants visited by M. grandis and indicate the degree of specialization of this bee in the collection of trophic resources, being conducted between November 2016 and October 2017. Altogether, 26 samplings were performed. The most common pollen types were: Solanum type (Solanaceae); Cassia mimosoides (Fabaceae/Caesalpinioideae); Mimosa caesalpiniifolia; Mimosa pudica (Fabaceae/Mimosoideae) and Miconia type (Melastomataceae). The months with greatest wealth of pollen types were: July, May and August. Arboreal and shrubby plants were the main resource suppliers for M. grandis, being 48.78 % (arboreal) and 34.15 % (shrubby). The degree of specialization of this bee is clearly associated with the abundance of resources throughout the year, Levins Index (B) for trophic niche amplitude 6.975, Standardized Index (B sta) 0.314, characterizing M. grandis as polyletic.

“…No Nordeste do Brasil, Locatelli et al (2004) registraram que as Fabaceae, Convolvulaceae e Asteraceae foram as famílias que se destacaram em número de espécies entre as visitadas por abelhas Antophoridae, Apidae, Megachilidae, Halictidae, Colletidae e Andrenidae. Modro et al (2011) afirmam também que as famílias Fabaceae e Asteraceae como sendo importantes fornecedoras de fontes polínicas. Espécies desta família são descritas como fornecedoras de recursos tróficos (néctar e pólen) para as abelhas.…”

Bioactive compounds and antioxidant potential of honey produced by africanized bees (Apis mellifera L.) in Piauí

et al. 2020

This work evaluated the bioactive compounds and the antioxidant potential of honey produced by Africanized bees (Apis mellifera L.) in the state of Piauí, Brazil. The analyses show that all honeys investigatedpresented features of the pollen type Mimosa caesalpiniifolia. The content of phenolic compounds ranged from 27.65 to 97.01 mg in GAE g-1 of honey, with an average content of 62.66 ± 20.46 mgEAG g-1 of honey. The total flavonoid contents expressed in mg of quercentin/g of honey ranged from 5.43 to 13.02 mg of QE g-1, with an average of 8.33 ± 1.86 mg of QE g-1 of honey. The best performance of antioxidant activity by reducing power was EC50 of 0.15 and the lowest performance of antioxidant activity with IC50 was 1.24. The highest antioxidant activity (DPPH) ranged from 66.11 ± 0.02mg EAQ 100g-1, while the lowest activities were 9.16 and 10.88 mg EAQ 100g-1. The results show that the contents of total phenolic compounds, total flavonoids, DPPH antioxidant activity, and the pollen-reducing power from Piauí were influenced by botanical origin.
