Rear declining bumblebees in captivity
Plowright & Jay (1966) induced mated queens of seven Canadian bumblebee species to found colonies in captivity, by confining them singly or in pairs in wooden boxes kept at 21° or 29° C, regularly provided with fresh pollen and honey solution. Twenty-eight of the 30 B. terricola tested and four of the nine red-belted bumblebees B. rufocinctus reared adults using this method, but a single yellow bumblebee B. fervidus did not. Some queens confined in waxed paper cartons laid eggs, but none successfully reared adult workers.
