Jim suggests the ocassional dwindling I see may be caused by Nosema Cerana
and suggests I check before destroying more comb.
That has ocurred to me. However, in each of the past two years I have been
diligent about making fall bee collections by yard and sending them to
Beltsville. They have reported 'no nosema', which astounds me. I am
careful to collect crawlers as well as bees from the brood nest. 50 miles
away is a commercial migratory beekeeper who gets reports of *millions* per
bee. But then, he is migratory and goes to FL and ME every year.
To me, this is truly a minor problem. Perhaps 1-2 observation hives a year,
plus 3-4 production hives. On the other hand, I started beekeeping in the
late 60's and never saw such symptoms before Varroa.
Someone questioned what I meant by 'contaminated comb'. I meant
contamination with fluvalinate and coumaphous. Although I no longer use
either, I did for several years and it will be several more years before my
hives are free of combs used during that period.
In the last two years I had bees draw about 1200 deep combs, but with about
200 hives I have a ways to go in replacing comb.
