Rear declining bumblebees in captivity Bee Conservation

Almanza (2007) reported rearing four colonies of the Neotropical pocket-making species B. atratus from wild-caught queens in Colombia. Kept alone under standard rearing conditions, the queens began egg-laying within one week. The colonies lasted between 97 and 183 days, and produced between 40 and 145 workers, but none produced any new queens or males.
