This is not a “How You Should Keep Bees” site; rather, I’m a proponent of “Whatever Works for You” beekeeping.  I’m a “data over dogma” guy, and I implore my readers to correct me on any information at this website that is out of date or not supported by evidence. - Randy Oliver

Beekeeping Through the Eyes of a Biologist
  1. de Groot 1953

    Thanks to Google for scanning this pioneering and widely-cited study.  Since this study is monumentally important to understanding honey bee nutritional requirements, I’ve unsuccessfully attempted to track down any copyright holder for permission to share it.  But as I understand copyright law, since this reprint does not contain any indication of this pre-1978 publication being […]

  2. Observations on Pollen Subs

    Observations on Pollen Subs Part 1 First published in ABJ July 2021 Randy Oliver ScientificBeekeeping.com I get a lot of questions about what the bees do with pollen subs, why, when, and how to feed them, or even if it’s worth the effort. Since I’ve done a goodly amount of investigation on this subject, allow […]

  3. A Comparative Trial of the Pollen Subs 2020: Part 1

    A COMPARATIVE TRIAL OF THE POLLEN SUBS 2020 Part 1 Beekeeper-Funded Research First published in ABJ July 2021 Randy Oliver ScientificBeekeeping.com California has been in a “mega-drought” for a decade. In many areas, there is not enough natural forage in late summer for building colonies back up to cluster sizes large enough to supply strong […]

  4. Randy’s Amino Acid Calculator

    In my research on pollen subs, I’ve come to find that some outperform others. Based upon their analyses, there’s a strong case to be made that getting the essential amino acids (EAAs) into proper balance is very important. So I created a calculator to help any beekeeper or manufacturer to check the EAA ratios of […]

  5. A Field Trial of Probiotics

    A Field Trial of Probiotics Beekeeper-Funded Research First published in ABJ May 2021 Randy Oliver ScientificBeekeeping.com   In recent years, we’ve learned that the honey bee gut hosts a microbiome consisting of several core groups of bacteria (Figure 1), which if disrupted, may have detrimental effects upon bee health [[1]].   Many beekeepers, in the hope […]

  6. A Test of Thermal Treatment for Varroa: Part 2

    Beekeeper-funded Research A Test of Thermal Treatment for Varroa Part 2 First published in ABJ April 2021 Randy Oliver ScientificBeekeeping.com Last month I covered the theory of using thermal treatment (hyperthermia) to control varroa, and some of the designs of devices on the market.  I’d like to now answer some questions regarding thermal treatment. I […]

  7. Calculation for nosema spore count using a hemacytometer

    calculation of nosema spore counts using hemacytometer Randy Oliver, ScientificBeekeeping.com From Cantwell 1970, assuming that each sampled bee is diluted with 1 mL of water.         Average spore count per bee is then: Average count per single small square x 4,000,000. Total count per large square (16 small squares) x 250,000. Or […]

  9. Oxalic crystals on bees after vaporization

    Crystals from oxalic acid vaporization on bees’ bodies Randy Oliver February 2020 In order to determine how OA crystals settled on bees’ bodies after an OA vaporization, I set a graduated microscope slide and a number of dead bees under a 16-oz inverted plastic cup.  I injected OA vapor briefly into a hole at the […]

    Mite Control While Honey is on the Hive Part 4 First Published in ABJ February 2021 Randy Oliver ScientificBeekeeping.com   In the three previous articles in this series, I showed the results of my field trial of summer mite treatments. Now let’s go a little further with extended-release oxalic acid (OAE).   A Note on […]
