    Default 1st varroa count after 24 hrs of Apivar-life.

    These are the first varroa drop counts after the initial 24hrs of Apivar-life.

    First number is the natural 24hr drop, second number is after 24hrs of treatment.

    61----193
    135---140
    44----238
    11----89
    10----46
    10----121
    47----435
    163---653
    38----202

    The before numbers as you can see, may not be a true representation of the mite population. I would think that it would depend on what stage most of the brood is in, whether it is mostly capped, or open. I used PAM on the sticky board. I used to use crisco, but PAM is alot easier.


    It's more fun posting than it is counting!

    Foor for thought, but I only treat when I hit a 50 count threshold for a 24 hour drop. It's part of the integrated pest management scheme to only treat when an economic threshold is reached, that is a mite count above 50 will be devastating to the hive and action is needed. Plus I think it may encourage or enhance strong natural selection for hives that keep low mite counts to not mess with what they are already accomplishing.

    yoyo, how soon after your first count (untreated) was your second count (treated).
    Interesting!, thanks for posting.

    The natural drop was taken on Labor day, 9-1 and the treatment given on 9-7.

    Todays' counts, second day after treatment.
    first number is the first day drop, second number is second days drop.

    Last year, I placed the four pieces of the treatment in #8 screen cages, this year, I left it out in the open. The bees are tearing it up trying to get rid of it. Last year, they just propalized the screens.

    After 4 days of treatment.
    I was not able to count yesterday, so I divided the count in half and put it for yesterday and today.

    This it the type of raw information that is really informative, good post Yo! One thing I might look at is the 2 hives with the high drops in the 1st. category. The numbers are high enough to say there may be some evidence of other factors such as hygenic behavior, that you might want to breed from, given some additional research.

    I did n't get to count for 4 days. I also ran out of PAM so the baords were not sticky. I think the counts are not reliable after abour 48 hours as the hive debris accumulates to a point where the mited can crawl away. So I will average the 4 day count.
