Pollen spectrum from honey samples of Melipona mandacaia Smith, 1863 stingless bee (Hymenoptera: Apidae) - DOI: 10.4025/actascibiolsci.v28i1.1061

The pollen spectrum from honey samples of Melipona mandacaia stingless bee was analyzed aiming at elucidating the alimentary resources used by that species. The identification of the visited plants was based on the analysis of pollen from honey samples collected in 11 hives located in São Gabriel county, in the semiarid area of Bahia State, Brazil (11º14S and 41º52W). The quantitative and qualitative analyses of honey samples were conducted in order to determine the pollen types percentages and frequency classes. Twenty-six pollen types were found, being the Piptadenia rigida type (Mimosaceae) considered dominant. Ricinus communis (Euphorbiaceae), Mimosa verrucata (Mimosaceae) and M. arenosa (Mimosaceae) were considered important isolated pollen. The most representative families found in the pollen spectrum of the honey samples were Mimosaceae, Euphorbiaceae, Asteraceae and Anacardiaceae
