I am looking for technical and practical information on a queen breeding system attributed to Farrar. I have only heard anecdotal stories about the system. Evidently the system excludes two breeder queens (using custom-fashioned parts cut from normal queen excluders) to two frames each in a brood chamber. The larvae are transferred from these combs. The bees are led to believe something is wrong with their queen(s) and will thus start queen cells. The system would be attractive to breeding scutellata, which "prefer" manipulation in very large colonies. Thanking you in advance Barry Sergeant Kyalami South Africa
