During 4 years (1994-1998) the pollination efficiency of bumblebees and vibration were compared on eggplants grown in unheated plastic houses. Munica and Faselis eggplant varieties were used as plant materials. Bumblebees activity increased between 9:00 and 11:00 am, the peek activity was observed between 10:00 and 11:00 am then decreases gradually and they stopped between 13:00 and 14:00 pm. They started foraging again in the afternoon between 15:00 and 18:00 pm. During higher activity of the day, 70-80 % of the bumblebees were foraging and each bees were visiting 3-7 flowers. Bumblebee pollination yielded higher (25%) than vibration. Fruit size (14% in weight and 7% in length) and number of seeds per fruit were higher (4 times) in bumblebee pollinated fruits than vibration ones.
