Affect queen status on bee bread consumpt!on and longevity of honeybee workers (apis mellifera l.)‎

Abstract EN

The investigation was carried out under laboratory conditions at Assiut Insect Research laboratory, ?lant ?rotection Research Institute during the active season of 2012.

The bee-bread conception and honeybee workers longevity were studied in reference to effects of the effects of certain queen statuses [egg-laying mated queen of one year old (M), supersedure queen (S), three-days old virgin queen (V), queen cell at the beginning of sealed (Q), without queen (W) and without queen / without bee bread (WAV)].

Means of bee bread consumption of newly emerged worker bees headed with tested queen statuses didn’t differ significantly.

The highest bee bread consumption through thirty- three days after emergence was recorded for the workers under Q status (48.513 mg).

The lowest consumption was noticed for workers under V status (37.626 mg).

Mortality rates of honeybee workers under different status of queen were calculated, indicated that the lifetime of honeybee workers under M, s, and Q statuses, was mostly similar, and recording 40.22; 3أ12.و and 31.و days, respectively, while the workers under V status, their LT 50 extended to 41.55 days.

For caged worker bees under WAV status, their longevity shortened LT 50 to 11.75 days in compared with the workers under w status where their LT 50 (21.50 days).

It is clear that the different queen statuses play an important role on the bee bread consumption and also play an important role on influencing the longevity of honeybee workers.
