RESUMO

Four colonies of Plebeia saiqui (Holmberg, 1903), of São Francisco de Paula, were studied during the period from October/1998 to October/1999. The counting of the bees was proceeded monthly, differentiated workers that came back with and without pollen in the corbicula. Grains of pollen of pots previously marked were collected monthly and identified. The percentage of the pollen types of the samples was estimated: 20% of Asteraceae, 17% Myrtaceae, 15% type Meliaceae and 10% Euphorbiaceae. The remaining corresponds to other pollen types of small representation, besides those the were no identified. The climatic influence on the pollen collection was analyzed being used simple and multiple regressions. It was verified that in the spring and in the summer the temperature, the solar irradiation and relative humidity were significant for the pollen foraging. During autumn and winter the relative humidity had smaller influence in the pollen collection.
