    Re: Best Lens for Bee Photos?

    Buy a lens reversing ring for <$10
    Use a 50 mm standard lens reversed to get +20 diopter macro.
    Use a wide angle lens reversed to +40 diopter

    Look for a lens with a manual aperture control, as...
  2. Re: Marin Bee Survey: Hobby keepers - a net population sink

    Within the standard error for a Yes/No question and the small sample size, the two results (Formic vs. OA) are statistically identical.
  3. Re: Marin Bee Survey: Hobby keepers - a net population sink

    Squarepeg, the Marin data is reported in aggregate (i.e. 207 of 414 colonies under trial died in the TF superclass). If I had access to the per respondent data, I would analyze it using per...

    Re: Foundation color

    I don't see any substantial difference in the preference of the bees between natural and black.
    If you are planning on grafting cells, the black makes locating and lifting the new larvae a lot...

    Re: more tf mite counts

    I've looked at a lot of my "wild swarm" mite drop, and do not see the leg biting present. If that behavior is heritable, I wish it would get to the west coast pronto.

    Untreated mites show a...

    The South African Oxalis pes-caprae is an invasive weed in Mediterranean climates worldwide. Locally in Calif. it is known as "Bermuda Buttercup". It is mostly just a nuisance in my area, but in...

    Spring is here !

    Traffic jams at the entrance, as Live Oak (Quercus agrifolia) pollen, and Tasmanian Blue Gum (Eucalyptus globulus) pollen and nectar pour into the hives. The trees and humming.

    There is no worldwide correct answer to pollen supplementation.

    Re: Viability of swarms?

    Classic pattern here is young, enthusiastic hobbyists go on swarm chases. Since a lot of these hobbyists kill a lot of colonies, this is a good low cost way for them to test out their fairy tales...
  13. Re: Marin Bee Survey: Hobby keepers - a net population sink

    This is germane to Coastal Calif hobby beekeeping. The main honeyflow is Eucalyptus (January to May). Cut-down splits work to short-cut swarming, especially useful in suburban beekeeping where...
  14. Re: Marin Bee Survey: Hobby keepers - a net population sink

    No brood break indeed. The bees were working the Coast Live Oak (Quercus agrifolia) like mad *today*. Deafening buzz over the oak. Live Oak covers thousands of square miles in the coast range. ...

    Re: what kind of bee diseases is this

    The virus that mites inject into larvae weaken bees for a period after you kill the phoretic mites with OA. This is especially true of the chronic paralysis virus that generates "crawlers". Chronic...

  17. Re: Marin Bee Survey: Hobby keepers - a net population sink

    Repeated measures data from the Marin survey over several years shows the treat v. non-treat data is not a fluke, but is statistically valid at the p=< 0.0001 level. n= number of respondents, not...

    No, this data is Marin County.

  19. Re: Marin Bee Survey: Hobby keepers - a net population sink

    NO! survival on a percentage basis for the unknown lineage was worse. There were many more individual hives in this cohort (because on the emphasis on replacement of dead-out by captured swarms). ...

    Re: Mann Lake Ultra Bee Patties

    I've seen hives starve out from early sub even in my winter free climate. The sub induces brood rearing which is a massive metabolic drain -- you need unlimited carbohydrate coming in as well as...
  21. Re: Marin Bee Survey: Hobby keepers - a net population sink

    The survey has an interesting data table for survival by queen lineage. I hesitated to post it (because the colony count exceeds the other cross tabs by several hundred --indicating data funk).

    Re: 9 weeks later: Varroa update

    The color of the bee is under genetic control. The pale, blond bees you are seeing are a sign of inbreeding, and Italians often express this. Blond color is recessive.

    Bees will appear lighter...
  23. Re: Marin Bee Survey: Hobby keepers - a net population sink

    Heavens, No ! I don't migrate to the Ay-Mends, and I sell off hives young. So I stay ahead of the mortality curve.
