    Default VSH Behavior In Action

    Hi Beesource folks,

    I finally added this USDA Bee Breeding Lab ( Baton Rouge) video to YouTube.

    It demonstrates VSH behavior: location of infested cell; removal of pupa; disruption of mite's reproducing activity.
    Seeing bees with this trait locate and disrupt Varroa Mites is still amazing, years after VSH was first selected for.

    Now, VSH behavior has been incorporated into productive populations giving bees and beekeepers
    a better chance with the Varroa mite and associated issues.

    Here's the video:

    Enjoy!

    Adam,

    The video appears to show a heavily infested frame for demonstration purposes. VSH stands for Varroa Sensitive Hygiene, but in my experience there is high percentage of "mistakes" made in uncapping healthy cells. It has been a while since I checked this, but has the error rate improved?

    Hi Joe,

    I didn't make the video so I don't know what the infestation "rate" was. However, that they remove a pupa and disrupt a mite is plain to see.

    The main selection for VSH as of now isn't the uncapping/recapping behavior. It is selecting for colonies that have higher levels of
    non-reproductive mites. Reduced mite population growth is also important to quantify in the selection.

    I think you were referring to issues with this selection:See Select on mite:

    Adam,

    I have read that. The lower reproduction rates have been around for a long time, but that is a tough one to tease out. Perhaps the mites are just too tired.

    The uncapping/recapping error rate may not be a selection protocol, but it is part of the behavior nonetheless.

    Thanks for posting Adam. Got V.P.Queens in 90% of my hives. Very satisfied.
