Resumo
The Scaptotrigona aff. Postica bee found in the In the Northeast (Maranhão, MA-Brazil) is
the main agents of pollination and conservation of local biodiversity as well as the major
source of income (honey, propolis, pollen and resins). These inputs are for nutritional and
have several medical applications (bactericide, fungicide and virucide). This stingless bee is
not yet fully standardized, and studies are needed to obtain knowledge about this species.
The relevance of this investigation is to understand the eating habits of this bee. There is
controversy regarding their eating habits, that is, ingesting soil is a bee eating habit, but
(apparently) this does not happen with this species. This study aimed to propose the
multielemental characterization of Scaptotigona aff. Postica bee (MA-Brazil), as well as the
characterization of the soil around the hives. Soil ingestion is a critical route of exposure to
contaminants. Stingless bees and soil samples come from a meliponary in the Barra do Corda
city (MA). Two analytic techniques were applied for this investigation: Instrumental Neutron
Activation Analysis (INAA) and Energy Dispersive X Ray Fluorescence (EDXFR). These
data are the first estimates of chemical elements in these samples and provide benefits to
beekeepers regarding their characteristic specifications. In addition, correlations between ion
and metal in soil and bees can help clarify the feeding habits of this species.
