Rear declining bumblebees in captivity
Chiang et al. (2009) documented rearing of two montane oriental species, B. eximius and B. sonani in Taiwan. Queens were induced to form colonies by confining them alone in wooden boxes at 26°C and 65% relative humidity, under red light. Of 53 B. eximius queens, 40 (76%) laid eggs, and 31 produced mature colonies. Of 37 B. sonani queens, 27 (73%) laid eggs and 22 produced mature colonies. B. eximius produced significantly larger colonies with on average 120 workers, 210 males and 25 queens, compared to 53 workers, 102 males and nine queens on average for B. sonani.
