Royal jelly production from swarming honey bee colonies

Today royal jelly production is a part of beekeeping industry.
The research was conducted in order to survey possibility of royal jelly production in Iranian beekeeping system.
20 honey bee colonies containing one year old sister queens and same contents of the hive were divided into 2 groups, randomly. Natural queen cells of control colonies removed in order to prevent swarming. Other group colonies organized using integrated usual swarm control methods and 4-hour method to produce queen. The grafted cells were introduced to these colonies in three times and in each time the organization of the hive contents was changed. At the end of each stage, number of accepted cells and amount of produced royal jelly was recorded.
The total number of accepted cells was 216.1, and amount of harvested jelly 273.67mg/cell or59.33gr/hive in 3 stages. There was no significant difference between groups from the view point of honey yields.
Generally, this trial showed that using this procedure we can produce a significant amount of royal jelly from the hives, as well as control of swarming.
