    Have a hive from a nuc that built up real quick this past spring. It seemed to be doing pretty well, in fact it was the only hive that I got honey from this year. When I tested for mites in August though, my other 3 hives had between 0 and 3 mites per 100, and this one had about 8. I gave...

    Construction and Rescue of a Molecular Clone of Deformed Wing Virus (DWV) European honey bees are highly important in crop pollination, increasing the value of global agricultural production by billions of dollars. Current knowledge about virulence and pathogenicity of Deformed wing virus...

  4. Diseases and Pests
    Hi All, I've been on this forum for 3 years and have made several good contacts through it and not to mention that I have even acquired some pretty valuable information from several other members on here as well. I have stated before that one area of beekeeping that I'd like to further my...

    Overwintering Is Associated with Reduced Expression of Immune Genes and Higher Susceptibility to Virus Infection in Honey Bees The eusocial honey bee, Apis mellifera, has evolved remarkable abilities to survive extreme seasonal differences in temperature and availability of resources by dividing...
  6. Treatment-Free Beekeeping
    Hello folks, I have one hive that has been doing fine treatment free for 9 years. Last year I collected and hived a swarm from this hive. The hived swarm was over wintered in a deep hive body and by April of this year they had drawn out all the frames in the deep. It was thick with bees...

    Infectivity of DWV Associated to Flower Pollen: Experimental Evidence of a Horizontal Transmission Route Deformed wing virus (DWV) is a honeybee pathogen whose presence is generally associated with infestation of the colony by the mite Varroa destructor, leading to the onset of infections...

    Increased Tolerance and Resistance to Virus Infections: A Possible Factor in the Survival of Varroa destructor-Resistant Honey Bees (Apis mellifera)The honey bee ectoparasitic mite, Varroa destructor, has a world-wide distribution and inflicts more damage than all other known apicultural...
  9. Bee Forum
    I checked on a hive earlier today and I have a dead out. I can't complain really, my second in over four years, but sad nonetheless. I'm thinking died due to small cluster and a cold snap. I'm hoping you might be able to give some insight. Attaching pictures in case they might help. Here are...

    Imported bumblebees pose 'parasite threat' to native bees By Victoria Gill Science reporter, BBC News Between 40,000 and 50,000 bumblebee colonies are imported into the UK every year Bumblebees imported from Europe carry pathogens that pose a threat to native honeybees and bumblebees...

    What is the best treatment for varroa mid summer? I started with a package in the spring and didn't treat them. We now have varroa and DWV, even after a recent break in the brood cycle. Temps easily go into the 90s every day, eliminating a lot of our options. I also need something that will...

    Varroa-Virus Interaction in Collapsing Honey Bee Colonies In colonies where varroa treatment reduced the mite load, colonies overwintered successfully, allowing the mites and viruses to be carried over with the bees into the next season. In general, AKI and DWV titres did not show any notable...

    Pathogen Webs in Collapsing Honey Bee Colonies Although pathogen identities differed between the eastern and western United States, there was a greater incidence and abundance of pathogens in CCD colonies. We identified novel strains of the recently described Lake Sinai viruses (LSV) and found...
