  1. Re: Penn State "COMB" project posts Dec 2019 update

    There is a study on pesticides in beeswax that is worth reading. It is hard to argue with chemicals proven by gas chromatography. The focus in this thread seems to be on miticides in beeswax, not...

    Re: Typical size of winter cluster??

    This varies depending on genetics with average winter cluster size of a colony of Italian bees covering between 5 and 9 Langstroth deep frames. Carniolans will cover about 5 frames. Pure Mellifera...
  3. Re: Penn State "COMB" project posts Dec 2019 update

    It is almost funny to read threads like this one and see the interplay between different philosophies. JWC started the thread as a way to pooh-pooh treatment free methods. Posts then accumulate...
  4. Re: Penn State "COMB" project posts Dec 2019 update

    Did you ever feel like you were running a race with a ball and chain tied to your leg? That is effectively what bees are doing so long as we continue to prop up susceptible genetics. Extreme...
  5. Re: German Black bees in the Southeastern US actually Apis mellifera iberiensis?

    I would like to post the exact mixture of genetics in Buckfast bees, but that would be an impossible task. Suffice to say that at least 20% of their heritage is from Mellifera and another large...
  6. Re: Penn State "COMB" project posts Dec 2019 update

    MSL, Shh, he has a drum to beat.

    I won't quote more of the article, but will note that chalkbrood and Capensis takeover were highly rated reasons for colony loss. The problems with hive...
  7. Re: Penn State "COMB" project posts Dec 2019 update

    That is an incorrect reading of a question that was actually addressed to JWChestnut. South African beekeepers had very little choice. Instead of continually propping up their bees with mite...
  8. Re: Penn State "COMB" project posts Dec 2019 update

    beemandan is one of the very few I would use that method of arguing with.

    Did you read the Arista page?


    How then do you explain what happened in South Africa?
  9. Re: Penn State "COMB" project posts Dec 2019 update

    It is more accurate to say that bees heavily infested with mites die. Period. Bees that are consistently treated will live but never develop mite resistance. Mite bombs still destroy too many...
  10. Re: Penn State "COMB" project posts Dec 2019 update

    Thank you beemandan. I agree with you that the biological cost of VSH is very high. My experience with high VSH bees is that they never build up to a strong enough colony to make a good crop of...
  11. Re: Penn State "COMB" project posts Dec 2019 update

    I'm 60 which is getting on up there a bit, but not good enough to go back to the early 1900's.

    beemandan, I'll challenge you the other way. What do you think are the most important mite...
  12. Re: Penn State "COMB" project posts Dec 2019 update

    IMO, this is not relevant. Bees may exhibit a range of mite resistance traits. Brood breaks are one of the traits. Swarming repetitively creates brood breaks. The two most effective mite...
  13. Re: Penn State "COMB" project posts Dec 2019 update

    Noting that Roland is older than dirt if he remembers beekeeping from before 1914.

    Beekeepers exploited swarms to the maximum back then often doubling or tripling colony counts in a good year. ...

    Re: Seeking advice for Breeder Queen

    Check with Harbo. Queens are expensive, but if you want proven mite resistance, he has it.

  15. Sticky: Re: Beekeeping using Square Dadant hives, treatment free since 2005

    I took 2 supers of honey off of a colony today that was being used to store them. One was moved to a hive that needed the stores for winter. One is here at the house waiting to be extracted.

    It...

    Sticky: Re: squarepeg 2015-2019 treatment free experience

    The hardest thing I did was burn 2 colonies that had AFB. I diagnosed it myself but had the state apiary inspector come out and verify that it was AFB. I only had 5 colonies at the time. The two I...

    Re: Definition of "Artificial Swarm" ??

    First, define a primary swarm. A primary swarm is a group of bees that separates from the parent colony with a queen (usually the old queen but sometimes a virgin) and moves to a new home. The bees...
  19. Sticky: Re: Hive designs and their advantages and disadvantages

    Italians were bred - and still are today - to go into winter with large colonies. This does not necessarily correlate with consuming more stores over winter. They generally start brooding earlier...

    Re: Two untreated hives in my bee yard

    There is no "dogma" involved. It is a solidly proven concept, but repeatedly misapplied. Mite resistance is very clearly genetic and it is not just based on one trait such as VSH. Where this goes...
  21. Re: Will bees pollinate fruits an vegetables inside a.....

    I've watched my bees fly out of the hive less than 5 feet to goldenrod plants to forage. To be fair, the goldenrod was at peak bloom and had so much nectar you could shake it out of the flowers.
  22. Sticky: Re: Beekeeping using Square Dadant hives, treatment free since 2005

    Temps hit 68 degrees about 1:00 pm with bright sun so I opened the 3 nucs up that I have at my house. The nuc that I've set aside for SquarePeg was strong on bees but short on stores. I gave them...

    Re: Cell size survey.

    I tested 4.9 extensively from 2005 to 2016 and reached only one conclusion. My bees were unhappy with 4.9 cells. I could force them to accept the foundation and they would draw it, but over time...
  24. Sticky: Re: treating vs. not treating for mites: opinion thread

    This is just practical experience and not scientifically proven. My experience is that around 10% of the bees in a colony have to exhibit mite resistance traits for the entire hive to be classed as...

    Re: How do bees ventilate in the winter?

    When temps are very cold, bees cluster tightly together and generate heat by vibrating muscles. This requires energy from honey which results in a lot of water vapor being released. With cold hive...
