    Re: High mite load opinions

    JwPalmer: I have one mutt queened hive out of nine in the apiary which has had extraordinary phoretic mite loads for two months during nine OAV treatments. I am keeping the hive and queen to see if...

    Re: Thermal with VOA ?

    One more thing LJ, if you do attempt this thermal approach, please install an adequate array of thermocouples to verify the elimination of temperature gradients above and below your target kill...

    Re: Thermal with VOA ?

    Comments for LJ: Using heat to raise the temperature is feasible - maybe. I do not see any requirements spelled out. I do see remove the brood from hives and leave the bees behind with their Varroa...

    Sticky: Re: Today in the Apiary

    mischief and Lalldredge: Dumb mistake i make on one OAV treated hive - I did not seal the sticky board until the 3-day DDC count. It was licked clean by mice ( I believe). I always seal the sticky...
  5. Sticky: Re: treating vs. not treating for mites: opinion thread

    Yet this colony, one of nine, stands out when when counting dead varroa. Eight hives showed the significant impact of fall migration, peaks >500 per treatment, including one that had a brood break...
  6. Re: How many OAV treatments in winter can they tolerate?

    Thanks for posting "msl", that's the source of my 2X, 14 days apart winter OAV. It works as I did not have to treat again until the fall Varroa invasion arrived.

    Sticky: Re: Today in the Apiary

    Upgrading my Beekeeping-Honey Extraction room - lucky me - so I can clean it easily. Snow on the ground, building 5-sided insulation boxes next and waiting for winter solstice to perform the final...

    Re: OAV, putting the risk in perspective

    Lamarcarama: Some special advice when handling oxalic acid OA - wear eye protection. I use my bee jacket veil and wrap around prescription sunglasses. I have taken people to the hospital for lack...
  9. Sticky: Re: treating vs. not treating for mites: opinion thread

    Has anyone in the TF or treatment community noticed a trait whereby the colony appears to not participate in robbing? The effect I have noticed is a very low Varroa count measured by counting dead...

    Re: Bottom Board Mite Counts

    I assume you mean alcohol wash for " mite counts". I'll take a factual post treatment Dead Drop Counts (DDC) and interpret over lagging, highly sensitive statistical analysis methods any day. This...

    Re: OAV overdose?

    Hi Biermann, Feeding my grandkids my honey is not a science experiment ( my daughter would disown me) but it is a vote of confidence. I agree with the "lowest risk" comment for OA treatments. I...

  13. Re: Is it feasible to control swarming without performing a spring split?

    Worth reading Wally Shaw for Swarm prevention and increases plus other options for managing bees. I cannot find queens, old eyes, so I move all brood and queen cells above a QE early in the day. ...
  14. Re: Is selfishness hardwired in homo sapiens?

    I have had similar thoughts but have focused it on honey bees for now. It seems honey bees are extremely efficient and altruistic. That is until the end of the "flow". After 35 million years they...

    Re: OAV, putting the risk in perspective

    LJ, Love the reply's logic! With a touch of sanity added. I believe there is a German safety report out for just that application, OAV outdoors. I believe it concluded that it was "safe" or within...

    Re: OAV, putting the risk in perspective

    JWPalmer, Couple of points worth noting, I think, based on my research efforts:

    1. US EPA approval is based on the Canadian Label. After an extensive search I gave up on trying to find the basis...

    Re: Is the Bee-Space necessary ?

    Somehow I think you are missing some requirements. A third dimension? Parallel planes? Forces? Mass is a cubic function and area is a squared function so the Jolly Green Giants legs will fail...

    Re: Global Warming

    Walking has mysterious affects. Maybe because it provides time to enjoy the air and think. I personally liked day-hikes and backpacking. Been living for a while and never saw a "Hoax" change the...

    Re: OAV overdose?

    No matter the path taken, there is always a "concern". The interesting fact to explore is why bees bring in so many different chemicals. Is the world is changing too fast for the bees to...

    Re: OAV overdose?

    Laboratory analysis has already been done in the EU. From memory: 1) It is difficult to find OA in honey due to masking ny formic acid and the very short half life of OA in honey but it is a natural...

    Re: OAV overdose?

    There is a retired Maine State bee inspector who has claimed that most Maine hives almost always have some brood - all winter. A bit north of me.

  24. Observations from 2019 Fall OAV treatments repeated 8 times.

    Three years in a row I have experienced what I think are serious horizontal spreading issues of Varroa or Varroa Bombs in my neighborhood. I have been trying to understand the source of the Varroa....
