Sixty-two bee pollen samples were collected between March/ 2004 and February/2006 from colonies of A. mellifera installed in the study area. The pollen-traps were placed at the entrances of the hives by a 24-h period, starting at 18.00 h. The samples were processed in the Plant Micromorphology Laboratory (LAMIV) of the Universidade Estadual de Feira de Santana (UEFS), Feira de Santana,
Bahia State, Brazil.
