    It would be good to source where the efb came from. Just another reason to promote local stock. Again, the biggest risk to bees is commercial beekeeping, the masking of problems, and the movement...

    So the inspector came by, did sugar shakes, mites around 3 percent overall with an outlier at 6 percent and .33 if memory serves. Neglected to take brood samples at the same time. Too busy. She...

    When my inspector came through, she thought putting gaps in the broodnest was contributing to chalkbrood. Though honestly the worst of the chalk brood I got rid of a long time ago and is less than...

    In systems theory selection is a central principle. We have seen it over and over again in all sorts of systems. A new problem, followed by a genetic shift. Most beekeepers still think they are...

    Re: Larder Beetles

    I have a few of these too with samples sent in to id. I was scared that it was small hive beetle (which we don't have yet). I don't see many of them so far but I like to keep boxes of comb stored...

    I haven't seen any evidence of alternative explanations, but that doesn't mean they don't happen. Between last fall and spring not much chance of any of those scenarios working out. I'm sure they...

    I've decided to requeen still. A large proportion of my hives had fall mite counts under 10 percent, some under 5 percent and they were strong this spring. My strongest 2 year survivor was around...

    I was placing some queen cells today at one of my sites. Since I was there I tried to find and kill a queen of a hive that had a 30 plus percent brood mite count last fall. I couldn't find her, but...

    I think this thread is very timely. I will be keeping an eye out for this scourge. Euthanasia, equipment destruction will be my strategy. Luckily my bees and equipment are not so expensive.

    There would be a big difference between your and my results. Typically sugar shakes done now (the start of my queen rearing season) would yield few mites compared to the late summer fall season. I...

    I think the mite counting and tracking outcomes is proving useful. My writing is not the best so the editor will have to wrestle it into some sort of shape. May take some time. I will post a link.
