Rear declining bumblebees in captivity
In a replicated, controlled trial, Génissel et al. (2002) demonstrated that the pollen content of the diet significantly affects the fecundity of B. terrestris in captivity. Twenty groups of three workers fed pollen from fruit trees Prunus spp. or a mix of pollen including fruit tree pollen, produced more offspring (average 14-19 adult males produced/group in 95 days) than 20 groups fed pollen from dandelion Taraxacum sp.or willow Salix sp. (average 0-8 adult males produced/group). The protein content of Prunus pollen was shown to be higher (average 27.5%) than other pollens in the trial.
