I apologize for not remaining in the discussion relating to winter bees
- esp. since I initiated the topic.
Questions were raised relating to the difference between summer and
winter bees.
Extracting information from Beekeeping Study notes - Modules 1,2,3 and 4
- J.D. and B.D. Yates published by Bee Books New and Old (ISBN 0
905652-33-9)
Young bees after emergence consume "large" amounts of pollen causing
development of the Hypopharyngeal glands and fat deposits. This allows
for the creation of corporal protein stores.
In summer: these stores are used to create brood food. Studies show that
more brood food produces by an individual bee the shorter its life span.
In winter: late emerging bees have limited brood to rear. The
Hypopharangeal glands remain plump, whilst the fat bodies are numerous
after consuming pollen from late flows. fat being stored on the dorsal
side of the abdomen.
Winter bees in this situation are somewhat similar to worker bees that
are in a queenless situation.
A table is present in the source being mined:
Bees in spring /summer have average life spans 3.5 to 4.5 weeks
Those considered as winter bees (emerging in August through till
October) have average life spans of 29 to 24 weeks (August bees having
the longest span).
I suggest that these figures may vary due to race, type of bee and maybe
situation.
Regards,
Peter
