Rear declining bumblebees in captivity
Gurel & Gosterit (2008) found B. terrestris queens were more likely to lay eggs and found colonies, and laid eggs more quickly, when they had been confined with a single B. terrestris worker, compared to queens confined alone, with a honey bee worker or with a B. terrestris pupa. These laboratory experiments were carried out at the University of Akdeniz, Turkey, following hibernation and CO2 anaesthetic treatment of laboratory-reared queens.
