Relationship between royal jelly production and number of queen cups in the honey bee, Apis mellifera L

, : Relationship between royal jelly production and number of queen cups in the honey bee, Apis mellifera L. Bee Science 3(1): 44-49

The effect of different numbers of queen cell cups on royal jelly production at 2 and 3 days after grafting was determined. Queenright colonies of a selected A. mellifera stock (20 000 bees/7-frame colony) were given 64, 96, 128, 160 or 192 golden-yellow plastic cups in 2-day royal jelly production trials in March, or 68, 102, 136, 170 or 204 cups in 3-day trials in July. Mean weight of royal jelly/cup decreased with increasing number of cups in both trials.
