Resumo
Field work was carried out on the campus of Universidade Federal de Juiz de Fora, Juiz de Fora-MG, between August 23, 1999 and June 06, 2000. It was investigated the foraging activity of seven colonies (three on pre-emergence, three on postemergence and one on decline), from 8:00 a.m. to 6:00 p.m., totalizing 70 hours registered. The foraging activity has taken place all day long in all developing stages, being more intense between 10:00 a.m. and 2:00 p.m., the hottest period of the day. Allobservations had a positive correlation between the number of departures to forage and the temperature and a negative correlation between the departures and the relative humidity of the air. The efficiency index to the (prey forraging behavior) forage of prey was 13,04% to the pre-emergence stage, 22,92% to the post-emergence and 6,67% to the decline, showing a bigger foraging activity to the postemergence colonies. In all observations the mostcollected material was the nectar (44,40% to100%).
