  1. Multiple OA Vap treatments

    Beekeeping 101
    Turns out my mite control early in the year was not as effective as expected, so I have one hive with an excessive mite load. This is my second year as a beek, so still dialing in how to be a beekeeper rather than a varroa mite keeper. I did a full course of OA vaporization over the last two...
  2. brood break varroa mite treatment by adding a queen cell (requeening)

    Treatment-Free Beekeeping
    Suppose you are making queens. You have bad hives that you want to treat for varroa (with an artificial brood break) and requeen. You want to breed from and not treat your good hives. How do you do this? The goal for bad hives Apply the treatment. requeen My simplified definition of a brood...

  4. Parasytic mite syndrome vs sac brood vs sac brood?!

    Diseases and Pests
    Hello fellow beeks, Could someone explain the difference in symptoms and look of parasytic mite syndrom, sac brood and chalk brood? What are the causes of each and how could they be treated? I'm having a really hard time when diagnose them. Cheers! F.
  5. OAV treatment in honey producing hive

    Diseases and Pests
    I live in south central Kansas and typically keep a few colonies of bees for honey production. After several seasons of heavy loss due to varroa, my partner and I decided to invest in a vaporizer to treat our colonies. My question is timing. I've read material by Randy Oliver and others, and...

    Observation Hive Forum
    How do you all treat for mites in a observation hive? I had thought OAV was really the only method, is there another method? Thanks Jason
  7. Would tropilaelaps mites really be that bad?

    Diseases and Pests
    From what I've heard people say tropilaelaps reaching North America and Europe "WOULD BE THE END OF THE WORLD" but from reading a little bit about them it seems like they would be less pestilent than varroa. My reasoning is this. Since tropilaelaps can only feed off of larvae and not adult bees...
  8. How to Make an Oxalic Acid-Glycerin Towel (Video Demonstration)

    Diseases and Pests
    I thought an instructional video would be useful to any beeks wanting to try the latest Oxalic Acid method. I've had the towels in my hives for about a month, but I won't really know how well they're working until I start testing for mites again in early June. //DELETED ORIGINAL VIDEO//...
  9. Varroa destructor Mites Can Nimbly Climb from Flowers onto Foraging Honey Bees

    "Scientific" Studies / CCD / Neonics
    Varroa destructor Mites Can Nimbly Climb from Flowers onto Foraging Honey Bees Varroa destructor, the introduced parasite of European honey bees associated with massive colony deaths, spreads readily through populations of honey bee colonies, both managed colonies living crowded together in...
  10. Calculating Mite Load Using Post-Treatment Drop

    Diseases and Pests
    I've been using oxalic acid vaporization for a couple years and it works great to kill mites with no apparent harm to my bees. The only part of the process I dislike is doing the sugar rolls to calculate the pre- and post-test mite load. This testing process is intrusive and I'm always afraid...
  11. Did I miss anything for overwintering? Did you?

    Bee Forum
    Hello, all. I'm a first year beekeeper in southeast Iowa. I bought a Russian pkg this year, installed it and took a mere 6 gal. I also recieved a swarm from a friend. Right in the middle between mean and dosile. Anyway, I was wondering if I missed anything. I've got ventilation holes in the...
  12. Varroa destructor, along with bee viruses, contributes to approximately 70% of colony

    "Scientific" Studies / CCD / Neonics
    Prospective Large-Scale Field Study Generates Predictive Model Identifying Major Contributors to Colony Losses Over the last decade, unusually high losses of colonies have been reported by beekeepers across the USA. Multiple factors such as Varroa destructor, bee viruses, Nosema ceranae...
  13. MITES in Nosema

    "Scientific" Studies / CCD / Neonics
    Identification, Diversity and Evolution of MITEs in the Genomes of Microsporidian Nosema Parasites Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous DNA transposons, which are widespread in most eukaryotic genomes. However, genome-wide identification, origin and...

  15. sticky boards and the possibe use of not-so-sticky boards

    Bee Forum
    I'd like to monitor mites better this year so will be using some sort of sticky board set-up, though I need to make it work with solid bottom boards. I gather that any thin material can be used and standard PAM spray can be used as the "sticky" material. Is it possible for bees to crawl on...
  16. Varroa mite lifespan

    Diseases and Pests
    What is the average lifespan of the varroa mite (Varroa destructor). It's a simple question that I don't have a answer to yet. I know they have a 12 day reproductive cycle, but not how long they can live. What got me thinking about this is; how long a break in brood rearing is necessary before...
  17. What Perentage of Varroa Mite Investation should one begin to treat a hive?

    Bee Forum
    I'm using the sugar shake method to identify and quantify my Varroa Mite levels. Does anyone know at what levels we should begin treatment? Also, I'm assuming if you know this you'd got some good links, references, etc. I'd appreciate it if you could share as well. Thanks in advance for your...
  18. Using drone frames for mite control-questions

    Diseases and Pests
    First year beekeeper here, I had questions about trapping mites with drone frames. I have a ten-frame hive and am about to add another chamber. Should I add one or two drone frames? Should I place them in the upper or lower? Should they be placed on each end? Any more tips would be appreciated.

  20. Larvae found outside hive??

    Bee Forum
    I noticed an almost fully-developed pure white larva laying outside the hive. Then I noticed another bee, almost watching the larvae a few blades of grass over. Does this indicate mite intrusion? I think I may be seeing mites around the hive, but with ants and other bugs around and with the...
