The effect of feeding pollen supplements on Apis mellifera L. population and the economic value of feeding colonies for spring or summer production of package bees was studied on thirty colonies of F1 Carniolan race. Five feeding treatments (6 colonies each), were evaluated from the beginning of dearth period (autumn season) to compare the benefit of feeding. Colonies fed with checkpea flour + Yeast (2:1) +syrup produced population of adult bees which significantly increased 4.25 times and 2.64 times than control treatment for spring and summer net income , respectively. The net income for feeding treatments of Extra bee, soyabean flour +yeast (2:1) + syrup and skimmed milk were high with ( 3.25 &2.52 times ), (2.43 & 1.9 Times ) and (1.4 &1.42 times) than control colonies for spring and summer production , respectively
