In this experiment, corn syrup was mixed with different feedstuffs and was evaluated in comparison to commercial sucrose fondant paste. Experimental treatments included a commercial fondant sucrose paste, Zarnam corn syrup paste, enriched Zarnam corn syrup paste (treatment 2 plus 0.5% vitamin and mineral supplement), Zarnam corn syrup vegetable paste, vegetable paste enriched with Zarnam corn syrup (Treatment 4 plus 0.5% vitamin and mineral supplement), and sucrose paste. Results showed that the commercial paste treatment had the highest population, and the enriched Zarnam syrup paste treatment had the lowest population (P<0.05). The larval population in all treatments containing Zarnam corn syrup, except the enriched Zarnam corn syrup paste, was similar to the commercial paste  (P<0.05). The highest pupal population was belonged to  commercial paste treatment, which was significantly higher than enriched Zarnam corn syrup paste and sucrose paste (P<0.05). The egg-laying rate of the queen in Zarnam enriched corn syrup plant paste, and sucrose paste treatments was statistically similar to commercial paste, while it was lower in other Zarnam corn syrup treatments (P<0.05). The lowest amount of pollen storage was related to the Zarnam syrup paste treatment, which was significantly lower than other treatments (P<0.05), and there was no significant difference between other treatments. Based on the results of this research it can be concluded that it is possible to prepare an enriched herbal paste by combining Zarnam corn syrup with plant materials, mineral and vitamin supplements, with the same effects on production performance of bees as commercial fondant sucrose paste.

This study aims to investigate the nutritional effects of organic acids, prebiotics, probiotics and (prebiotic + probiotic( combination on increasing adult bee population, neonatal rearing, beeswax production, pollen storage and hives weight gain before the honey harvesting season in Iranian honey bees.

This experiment was conducted using 25 Iranian honey bee colonies with the same sister queen and with the same conditions in a completely randomized design with 5 experimental treatments including control group (sugar syrup 1: 1), organic acid (8 cc per 1 liter of syrup 1:1), prebiotics (10 g per 1 liter of syrup 1: 1), probiotics (5 g per 1 liter of syrup 1: 1) and (prebiotic + probiotic) combination (10 g + 5 g per 1 liter of syrup 1: 1) and 5 repetitions for 30 days before the honey harvesting season.

The adult bee population in the colonies that received organic acid and prebiotic + probiotic( combination was significantly higher than the control treatment (p<0.05). Neonatal rearing and beeswax production increased in colonies that received organic acid, prebiotic, probiotic and )prebiotic + probiotic( combination compared to the control treatment (p<0.05). The effect of experimental treatments on pollen storage was not significant (p<0.05). Hives weight gain increased in all experimental treatments, except for the colonies that received probiotics, compared to the control treatment (p<0.05).

The results showed that the use of organic acid, prebiotic, probiotic and (prebiotic + probiotic) combination in bee stimulation feeding before the honey harvesting season can improve the performance of Iranian bee colonies.
