Good info, and yet another reason to get rid of that old comb. This year I plan to trash any comb that isn't a nice clean yellow.

Yes I see lower preproduction of mite here too but think one study gave percentages like 1.7/1.9 compared to 1.3 rate in old comb or something like that. I am just about hitting your one hundred percent losses lately.
So then which is it?However, Erickson et al.
(1998) found higher infestation rates with
A. woodi (Rennie) in colonies with new combs
than in those with old combs (5.2% vs. 1.2%
respectively). Recently, Hassan (2000) reported
that female V. destructor reproduced more in
new than in old brood combs.
That's too bad.I am just about hitting your one hundred percent losses lately.
GWW:Russ, if you read this, I am almost sure that I read one study that said the mite reproduction rate was reduced a bit in the old comb but I am not sure enough for you to rely on this but more to watch for it as you go though all the stuff you read. With your study, even if true, it might be a loss over all.
GWW:None of this means I will never add things to make things better. I may be given no choice but for now am still concentrating more on learning guitar then bees except to make sure I look and see as things happen to put in my brain for later thought.
GWW:I will think about the test kit though.
It's all been fun so far (except the stings). Maybe our mistake is trying to keep all of our bees in a yard together, where they can share diseases. Maybe we should try putting tiny masks on each bee...?Russ
Personally, I feel lucky. The last two year were the ones I was expecting every single year Including the very first year.. Now I have not decided direction and am not confident I can do a repeat of the beginning but don't feel I have much to whine about either.
