    Default Pin-Kill VSH Testing

    Expanding my testing this year

    Those of you that have done the Pin-Kill VSH Testing, explain how you have gotten the most reliable data and best results.

    Thanks. ....Don

    Don, I believe that pin-kill (like freeze-kill) is a standard test for HYG, but VSH is specific to uncapping live infested with varroa. To test for VSH, you need to have varroa infested brood.

    So, if I put a frame of varoa infested brood into my one Russell VSH hive they should visibly rip into it? I'll have to try that.

    ...I have no idea. I don't know what the "standard" way is that beekeepers test for VSH, or how a Russell queen would score on such a test.

    I would ask Rob how VSH is evaluated in his operation, and try to replicate that as closely as possible, at least as a starting point.

    http://vshbreeders.org/forum/index.php might be of some help.

    "Hygienic behavior is one of several known mechanisms of resistance against V. destructor (Peng et al., 1987; reviewed in Boecking and Spivak, 1999). Bees bred for hygienic behavior detect and remove worker brood infested with the parasiticmite Varroa destructor (Spivak, 1996)." http://dx.doi.org/10.1051/apido:2006065

    The Pin-killed Hygenic Testing is used very extensively in Europe as an indicator for VSH and is one of their required test for their breeder queens. I just don't speak German well enough to ask my questions and understand their response. (Arbeitsgemeinschaft Toleranzzucht - AGT - http://www.toleranzzucht.de)

    Thanks for the link to the VSH breeders forum Dean, I didn't know they thier own forum.
