I agree! I never said he suggested M tubule damage. Read again what I wrote
above.

I have sat through many of his presentations and the above statement as
written I think Marion would agree to.

CONCERN

" Marion Ellis researching (oa for several years) has expressed **concern**
at presentations I have attended ( ABF. Missouri State . Midwestern
beekeepers) over treating bees with oa any time **other than** the broodless
period which is around Thanksgiving in Nebraska"

Marion never said oa could be causing tubule damage. You did!

I know you said how harmless OA was in your articles and *may* be so but
researchers are looking hard right now at problems. Closer than at any time
in history in my opinion. Just because beekeepers around the world say any
product is safe to use in a bee hive does make it so.
Look at the problems caused by apistan & checkmite.

Has Marion checked in his oa research for damaged M. tubules before and
after OA use? Has Medhat? Has any researcher (other than the CCD team).
I don't think so or I am sure ehey would have shared the results. Findings
from the CCD researchers could possible teach us many new things about honey
bees and the way we care for our bees.


What are the effects of current treatments ? short term? long term?


 His reply:(Marion Ellis)
Randy,  I have never suggested that OA treatment affected the bees
Malphigian tubules.

Marion never did and I did not say he did. You are jumping to conclusions
Putting words in my mouth!

>I have stated that in the North Central Region
treatments applied in late November to broodless colonies are most
effective.

He has and has spoke on other times (summer) and the benefits and effects.

>  Treatments applied at other times are less effective, but
we have not observed any colony injury, even when treating 3X at 7
day intervals....feel free to post my reply. Marion

I guess this might be another case where all the beekeepers at the
Midwestern meeting need their hearing checked. I just contacted a couple
Marion has always told us the safe time and most *effective* time  to treat
is in the broodless period. Are you saying some brood and eggs are not hurt
during summer treatments? Give me a break!

Would then say as Marion says above that you  could treat 3X at 7 day
intervals all summer without any injury to the colony. Remember there are
MANY beekeepers on this list listening which have experience with OA further
back than either you or Dr. Ellis. Opps!

If I misquoted my long time friend Dr. Ellis I apologize. Why don't you post
the email you sent to Dr. Ellis saying your version of what I said on BEE-L?

Did it go like this:
" Bob Harrison said you think oa is causing M. tubule damage in honey bees!"

If so no wonder he said what he said:

Bob
