| 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... |

| The activities of four colonies of Plebeia saiqui (Holmberg, 1903), of São Francisco de Paula, Rio Grande do Sul, Brazil, were studied from October, 1998 to September. 1999, comparatively during the oviposition period and the diapause. The construction of the cells was monitored by direct observation of the nests. The duration of the diapause period varied from 76 to 168 days. Monthly, the bees that left and entered were counted for 10 minutes, at each hour, during the complete period of flight activity. Influence of meteorological factors on the activities of bees flight was analyzed through simple and multiple regressions. During the oviposition period was found that solar irradiation, temperature and relative humidity had a significant influence on bees... |
