15. Rogers, R.E.L. & G.R. Williams - Honey Bee Health In
Crisis: What is Causing Bee Mortality?-Honey bee colony
strength and health have been assessed by Wildwood Labs
Inc. from hives in various locations in North America since
2001. Also, working visits to western Europe since then
have provided a clearer understanding of the bee health
situation there. The picture that is emerging is
alarming - honey bee losses are severe in many countries.
When honey bee colonies die in large nubers, the cause is
often considered nysterious, and this leads to various
allegations and theories as to what caused the bee losses.
Using a Colony condition Assessment and Survival Prediction
Analysis (CCA/SPA) approach, it as been possible to define
the status of bee health in individual colonies and to
predict the chances of surviving winter.
A CCa is a process that measures a wide range of factors
that can affect bee halth or can be indicators of a
problem. This process must be performed in a living,
managed colony of honey bees. Samples are also collected
and aprocessed in the laboratory to complement the in-hive
assessment. This informaiton combined with data related to
equipment, apiary, environment, and management completes a
data snapshot of colonoy condition at the time of
assessment. Using provisional thresholds and interaction
considerations, it is possible to do a SPA to realize the
effects of multiple stressors. The system is objective,
unbiased, accurate and comprehensive.
What has become clear from using CCA/SPA is that honey bees
are suffering from what is being referred to as Multiple
and VArious Causative Agents Syndrome (MVCAS). This
syndrome is caused by additive or synergistic combinations
of more then one factor that affects bee health. The
combinations may vary among hives, apiaries, regions and
countries. The factors most frequently associated
with MVCAS are parasitic mites, diseases (including
viruses), managment, and nutrition. It is possible, using
CCA/SPA, to determine the specific various factors that are
contributing to bee mortality. As well, the system has been
found to be a good predictor of the chances of colony
survival over winter. Assessing all of the factors that
affect bee health at the correct time, and interpreting the
results in relation to provisional thresholds and
interactions, takes the mystery out of why honey bees are
dying.
Now Allen, this is from the Proceedings of the AMerican Bee
Research conference that took place January 8-13 at the
Sheraton Crescent Hotel in Phoenix, Arizona and is an
abstract of the conference.
Rogers is from Wildwoods Labs in Nova Scotia , Canada
Williams is from Dept Biology, Acadia Univ, Nova Scotia,
Canada
Found abstract interesting as we have discussed here on
BEE-L list multiple stresses coming together for a final
kill off, with last stress being the cause many believe,
yet here it is simply explaining how to relate all
together................
What a nice paper to get hold of I think and in CANADA
where Allen Dick lives and I sure would want to read more
in detail..... and then apply to
................."CCD"........ if I could get a full copy
by any chance Allen, sir even!
What you think?
Best Regards,
Dee
