Rear declining bumblebees in captivity Bee Conservation

A replicated laboratory experiment by Regali & Rasmont (1995) showed that four groups of captive B. terrestris workers fed on pollen mainly from oilseed rape Brassica napus ssp. oleifera (22% protein) reared more, larger, longer-lived males than four groups fed on pollen mainly from sunflower Helianthus annuus (13% protein).
