There is a direct relationship betwee production of honey bee and the rate of its colony. In fact, the more the population of the bee in the accumulation season of nectar, the more the rate of honey and nectar will be gathered, so that artificial nectar will be used instead of natural nectar to provide the energy requirements in time of lack of nectar in nature. In order to explain the effects of substituting the artificial nectar instead of natural one, factorial experiment on the basis of completely randomized design has been done with five treatments (four diets and a control group) and five replication on 25 colonies.The results indicated significant differences among diets (p<0.01). But considering the number of larva, there was not seen significant difference between right and left sides of the honey comb. Also there was not a significant difference among honey, starch+honey and sugar. so in respect of the food expense, sugar could be considered as the best food for increasing honeybee population and mixture of starch+honey and honey placed at second and third levels. conducted experiments on honey production indicated that there was a significant difference in confidence level of 0.05 among food treatments in honey production rate point of view. Comparison of means showed that food treatment swith starch+sugar and starch+honey. with high means and non significant difference with each other, had better effects on the rate of honey production rather than other foods.
