Pollen harvest by Apis mellifera L. (Hymenoptera: Apidae) in the Dourados region, Mato Grosso do Sul state (Brazil) Acta Botanica
D'Apolito,; Pessoa,Sheila Magalhães; Balestieri,Fátima Cristina de Lazari Manente; Balestieri,José Benedito Perrella.
We present data on the pollen harvest by Apismellifera L. at a central-western Brazil site not yet studied. Corbiculae pollen loads were collected during one year in front of the hive, acetolysed and slides mounted for optical microscopy. Identification followed comparisons with a local pollen collection. Forty-two pollen types were utilized by the bee; the most important families were Myrtaceae, Asteraceae, Euphorbiaceae, Brassicaceae and Poaceae. The genus/species level ranking of relative importance showed Eucalyptus (19%), Raphanus raphanistrum (13%), Poaceae type 2 (7.5%), Jatropha cf. gossypiifolia (7%) and Sapium glandulatum (6.5%). Overall, the majority of pollen types (80%) were not abundantly harvested, and a minority (4%) reached values of 10%....

Harvesting Season and Botanical Origin Interferes in Production and Nutritional Composition of Bee Pollen Anais da ABC (AABC)
NEGRÃO,ADRIANA F.; ORSI,RICARDO O..
ABSTRACT 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...
