Fig. 3. The mean amount of egg yolk taken daily by the subcaste members is shown for each treatment combination. Three 
colonies (A, B, and C) were used for the majority of treatments as shown. The same letter above two or more bars indicates that 
these means are not significantly different at the 0.05 probability level using Duncan’s Multiple Range Test.
