FLORES, F. F  e  SANCHEZ, A. C. First results of botanical characterization of honeys produced by Tetragonisca angustula (Apidae, Meliponinae) in Los Naranjos, Salta, Argentina. Bol. Soc. Argent. Bot. [online]. 2010, vol.45, n.1-2, pp.81-91. ISSN 1851-2372.

The melissopalynological analysis was performed on ten honeys samples of Tetragonisca angustula Latreille breeding in the locality Los Naranjos (S 23° 07' 19,2"; W 64° 40' 32,6"), Salta, Argentina. We found a whole of 49 pollen types. In the honey monofloral, the dominant types corresponded to: Anadenanthera colubrina, Baccharis, Citrus sp., native Myrtaceae and a type undetermined (type 6). The remaining samples were multifloral. 62% of pollen types corresponding to representatives of the Yungas mountain forest; types like Anadenanthera colubrina, Bocconia integrifolia, Parapiptadenia excelsa, Phyllostylon rhamnoides, Sapium haematospermum, type Myrsine and a set of native Myrtaceae, which constitute the first appointment as nectar sources for T. angustula. Also identified pollen from plants typical of anthropogenic environments such as Carica papaya, Citrus sp., Eucalyptus sp., Leonurus sibiricus, among others. These results provide a first approximation to the knowledge of the flora used by T. angustula and geographic origin of their honey, establishing the first record of mountain forest of Yungas.
