Chances are that the poor fruit set is due either to not enough female blossoms, or to poor pollination. The number of bees and/or flowers in the vicinity may be irrelevant, since gourds are mostly pollinated at night. My vines usually flower for a period of time before setting, then set large numbers... which is not unusual for any member of the gourd family.
