I believe you read my post incorrectly as the U.K. DID NOT find KBV in any
of the samples *we sent.*

Which led us to the conclusion KBV was brought into Florida with Hack.

My question:
We were told that KBV was not found in the yards in the area of the first
CCD find.
Can you or Jerry confirm?
Other USDA sources said those yards with healty bees were not tested for
virus. I believe we had sent samples from a couple the year before and virus
was turned up but no KBV.

The CCD working group constantly played down (myself and Danny Weaver could
not believe and said so at meetings) the FACT Kashmir Bee virus ( a known
bee killer in Canada) and nosema ceranae (a known bee killer in Spain) were
in 100% of the CCD hackenburg samples and dismissed as the root of the
problem and wanted funds to research further. Most beeks were quite as we
feld those researchers needed something new killing bees to get funding.

Commercial beeks knew the way to control both KBV & nosema ceranae in spring
2006 but not being some *new* problem killing bees little government help
would come.

Low varroa count keeps KBV at bay.

Low spore counts keeps N. ceranae at bay.

If so then most likely the source of the KBV.

 Hack had only recently started to send hives into almonds before his crash
so he could have picked up KBV in California but to my knowledge Hack has
never sent bees into the Midwest and before California strictly worked the
east coast.

I was writing about hive problems in the Midwest so perhaps the reason hack
suspected his problem came from the Midwest.

All the Florida virus issue was never written about as was the way Florida
beekeepers wanted things done.

Florida over winter around Umatilla , then Brazillian pepper and orange.
Then into blueberries and ending up on wildflower& goldenrod was Hacks route
before he started doing almonds.
Not sure the route now.

It takes awhile for a virus to reach the level that KBV was found in 100% of
samples (personal experience). Same with nosema ceranae. However with a huge
frame exchange in spring I believe could happen with two springs but *in my
opinion* not one spring. Hack & I never discussed bees from Canada being in
his operation but I heard rumors later.
