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.

The aim of this research is to investigate the effect of sweet paste containing AVP-4 on queen egg laying rate, carcass weight, population size, brood rearing, protein and body fat in European honey bees. In this experiment, 20 colonies with the same age and homogenized queen were used. The hives used were of the Langstroth type and the colonies were homogenized in terms of the population of newborns, the population of adult bees, and the amount of food reserves (pollen and honey). The field experiment was carried out in the form of a block design in four treatments, including the first control treatment of sweet dough without Nano-supplement, the second treatment of sweet dough containing 2.5% , the third treatment of sweet dough containing 5% , and the fourth treatment of sweet dough containing 7.5% of Nano-supplement in five replications. The amount of eggs, larvae and pupae was measured every 15 days and the colony population was measured in a frame. It was used to determine crude protein and body fat based on AOAC methods. The obtained results showed that there was no significant difference between the treatments in the entire experimental period by comparing the mean egg laying of the queen, brood rearing, population size and crude protein in the entire experimental period (P>0.05). Comparison of the average amount of fat (ether extract) had a significant difference among the treatments (P<0.05). The use of AVP-4 supplement in feeding honey bees had no significant difference between the treatments .
