  • 8. Congestion Primary Factor That Initiates Swarming Interferes With Queen Substance Distribution Stimulates Queen Cup Building
  • 9. Queen Age Colonies With A Queen Of The Current Season Rarely Swarm By The Second Season, The Chance Of Swarming Greatly Increases Colonies Headed By A Two Year Old Queen Swarm More Than Twice As Much As Colonies With A One-Year Old Queen
  • 10. When Colonies Are StrongAnd Are DevelopingRapidly, A Period Of GoodWeather After Some BadWeather Accentuates The“Swarming Fever.”
  • 11. Other Factors that May Affect Swarming Imbalance In The Age Structure Of The Colony, i.e. Too Many Nurse Bees Too Little Laying Space For The Queen Too Many Drones Poor Ventilation
  • 12. When Does Swarming Occur?Kentucky- Mid April To Mid May (Peak) 1 March to 1 JuneIthaca, NY (6 Year Study) Starts May 15 Peaks June 5-10 By July 15, 80% Done July 15-August 15, Almost No Swarming August 15-September 15, 20%Maryland- Swarming Begins One Month Earlier
