The research was conducted in order to determine the influence of pollen bees on the quantity of brood, honey and pollen at the time of flowering of Sophora japonica. The experiment was conducted on the apiary belonging to the Faculty of Agriculture of Belgrade - Zemun, Yugoslavia, in the period from 20 July to 10 August 1997/1999. The autochthonous bees breed Apis mellifera carnica Pollman was used in the experiment. The research established that the greatest inflow of pollen was recorded in the morning between 8 and 10 o'clock AM. The correlation between the number of pollen bees and the brood surface is strong; in the langstrooth hives bee colonies the correlation coefficient is 0.8127, while in the dadant blatt hive type bee colonies the coefficient is 0.8060. For the honey surface to be increased by 1 square dm it takes 5.4 pollen bees more in the langstrooth hive, while it takes 10.52 bees less in the dadant blatt hive type to achieve the same goal.
