Rear declining bumblebees in captivity
Pomeroy & Plowright (1980) described two hive designs in which they had reared several species of bumblebee in the laboratory, including the pocket-making Neotropical species B. atratus and the large garden bumblebee B. ruderatus. Both designs were internally cone-shaped, one made of metal, one moulded from porous concrete. The metal hive had a heating element, and its internal temperature controlled at around 30°C by thermostat.
