This study examined the effect of feeding diets with different pollen sources to queen bees (Bombus terrestris L) on the initiation of the colony. 120 fertile queen bees that healthily emerged from diapause were randomly distributed to six diet groups of different pollen sources: i) Poppy pollen (PP), ii) Chestnut pollen (CP), iii) Labdanum pollen (LP), iv) Poppy-Chestnut pollen (PPCP), v) Poppy-Labdanum pollen (PPLP) and vi) Chestnut-Labdanum pollen (CPLP). In addition, groups were fed sugar syrup (50 brix) ad libitum. During the rearing of queens, the room temperature and relative humidity were 27-28 degrees C and 50%, respectively. It was found that pollen consumption differed among the groups (P<0.01); highest and lowest in the PPCP and CP groups, respectively. The worker bee emergence time was earliest and latest in the LP and PP groups, respectively (P<0.05). Furthermore, the number of worker bees in the first brood varied among the groups (P<0.01), higher in the PPCP compared with the rest of the groups. On the other hand, the weight of queen and worker bees, first egg-laying time, and survival rate did not differ among the groups (P>0.05). In conclusion, this study suggested that supplementing bee diets with multi-floral poppy-chestnut pollen could enhance colony initiation of queen bumblebees through increasing pollen consumption and the number of worker bees in the first brood.
