This study examined the foraging activities and the influence of excessive foraging activity by B. ignitus workers on the quality of cherry-tomato fruits in cherry-tomato green-house. The peak time of pollination by B. ignitus worker was recorded at 8:00 and the average of foraging time on each flower was 11.7 secs. The total pollinating time of B. ignitus was 41 mins and 37 secs and its total number of visiting flowers was 195.2. The average time of staying on glowers was 8.8¡¾5.4 secs when two bumblebees were allowed to pollinate per Pyong in the green house of tomatoes for 24 hours , but it was two times shorter compared with that when one bumblebee was allowed to pollinate per Pyong for one hour. The stamen color of tomato flowers visited by the frequent visiting .
