    Default Anyone Check for Mite Biting?

    I am curious if anyone on the forum has attempted to examine mites from their colonies for signs of potential mite biting traits. I have bought myself a cheap pocket microscope, 60x-120x power, which should be more than sufficient to check for signs. I was wondering if there are certain protocols that need to be followed or is observation of missing limbs, etc. enough to make such a determination? I essentially just want to satisfy my curiosity either way.

    I tried, but my microscope is not good enough.
    And I realized, that ants damage them too.

    So a sign of bees getting rid of mites could be the amount of mites on the floor.

    One of my co-workers has a colony which just now has 60 mites a day on the floor board. They should be crashing or show some virus but they thrive.
    Itīs the second time he had such a situation, the first time the floor was inches covered with mites, the hive survived, but barely. It was not the same hive.

    Normally he treats such a hive but he was in hospital and they were left behind for months. The actual hive he wants to leave alone to see what happens. The neighbor hive got many of this mites too by drifting, but now numbers go backwards.

    What type of microscope were you using, Sibylle?

    Jeff, please update how your mite check works.
    I would want to buy a better microscope. Whatīs yours?

    I really believe the mite biting should be propagated. Itīs a much better trait than VSH, which only fights the symptoms and could come too late to prevent virus impact.

    Before you laugh too hard at my choice, read the reviews. I haven't received it yet, so we will see.

    If I can make any determination either way, I'll update.

    So I got my scope yesterday. I set up a section of fanfold insulation under one of the SBB I still have to see what I found. I set it up under one of my more populous hives that has been queenless for close to a month by now, so I knew the phoretic population should be high. Here's what I saw out of the 3 mites I found, one of which was crawling around. I set the insert up from 1:00 PM-4:00 PM today


    The white stuff you see circled was coming from the mite's carapace. It appears to have been "bleeding." This mite was still wriggling, but appeared injured.


    An attempt at showing where the white stuff was coming from the carapace.


    This one was much more promising as far as potential signs. This mite is missing appendages.

    Not sure what this means quite yet. The photos don't really do what I was seeing justice. I basically held my phone lens up against the lens to take the pictures. From what little I've seen, which isn't much, could be promising.

    For anyone interested, I'll keep updating with what I find.

    A better picture of the mite with missing appendages. I wasn't happy with the quality of the above picture. Definitive mite damage and a clearer picture of what I was seeing.

    Hey Jeff, thanks for sharing!
    Thatīs really wonderful, I must copy this.

    Iīm not sure but is the white stuff a male mite or a young one?

    The best I can describe it, it was originating from either a front leg or the carapace. It was a milky white, the consistency of perhaps egg yolk by the looks of it. It appeared to be coming out of the mite. The mite was slowly moving it's legs, on it's back. It appeared as if it were dying.

    The appendages look like being bitten off.
    Your scope is much better than mine, letīs see if I can order it.

    I ordered it today

    I like to see the mites in this state even if they are our friends....

    Here is a foto from Alois Wallners pages.

    Since ants eat mites I think it might be important to ensure that there are no ants on hive bottoms before making any studies.

    Very true, Juhani. That was my thinking on the limited time frame I left the board in. Less time for ants to find it. I didn't find any signs of ants, but can't entirely rule it out. Most ant behavior I've seen they carry their food with them back to the mound. I'll perhaps look at a way to ant proof the test.

    That's amazing detail on the link. Thanks.

    I tried to cover the board with sunflower oil paper but realized that on hot days the fumes disturb the bees.

    A friend told me to use baking soda around the rims of the board but this kills the ants and Iīm rather a friend of all insects.

    I think there will be one or two mites left to look at

    What if the ants make the damage to mites legs?
