Production of many crops benefits from elevated pollinator diversity and abundance. We assessed the effect of pollen supplement on the foraging activities of Apis mellifera in strawberry greenhouse. Since bees can learn floral resources in association with pollen rewards, we tested whether offering pollen supplement food enhances foraging activity and consequently increases pollination by honey bees in greenhouse. We observed number of departing and returning bees from the hive entrances with fixed interval from 10 am to 6 pm with temperature and humidity recording. And we checked number of foragers that visit artificial food (pollen: rice powder; 1 : 0, 1 : 1) and flowers. Honey bee foraging was highly dependent on the temperature inside the greenhouse. Minimum temperature for honey bee activity was observed from 14℃ with maximum activities at 33.1~33.3°C. Above 39°C, no foraging was observed. Foraging activity of bees significantly increased after offering pollen supplement food; average number of bees departing 23.3±3.06 and returning 24.8±3.51 were increased to 39.3±2.53, 44.9±2.91 respectively after offering pollen supplements. Frequencies of foraging on two different pollen supplements (high vs low protein) were not significant. Visiting duration of strawberry flowers in plots with and without pollen supplements were not different. Increased foraging activity by increasing the number of foragers that enhances high bee visitation rates by offering pollen supplement foods can be the indication of pollination efficiency.
