Evaluation of resistance of sponge gourd and pumpkin rootstocks to Fusarium wilt， selection of antagonistic microorganisms to Fusarium wilt，phenology investigation of bitter gourd， introduction of honey bees to help pollination of bitter gourd production， and the effect of environmental factors and flowering performance on bee pollination behavior in the facilities were conducted this year. In the Fusarium wilt inoculation test， two sponge gourd lines (96-157XL2 and 96-111XR3)， and 2 pumpkin lines ( 4 and 13) were chosen for better resistance to Fusarium wilt， which had the potential to be applied as rootstock for controlling Fusarium wilt of bitter gourd. In addition， sponge gourd line-95-153XL2 showed better grafting compatibility. Three antagonists were selected by dual culture. The bacteria showed activities to suppress mycelia growth of Fusarium oxysporum f.sp. momordicae. They had the potential to be applied for controlling of Fusarium wilt. Bitter gourd grown in the greenhouse produced female flower at lower nodes than that in the open field for 7-8 nodes. However， with the similar fruit growth period， the fruits produced in the greenhouse were less seeds， thinner and lighter.The trend of honeybee traffic activities was similar， which showed two peaks of leaving and returning hive at 0800 am and 1400 pm， respectively；however， bee foraging for pollination was only effective during the morning. In addition， the cooling treatment III made lower temperature and humidity of one day than those of control.
