Re: Hygenic test results on breeders
I once asked Marla Spivak about the pin test for hygienic bees, and she said the colony must be checked within 6 hours of killing the prepupa.
The test for bees that remove varroa that are reproducing in the cells involves placing a known number of mites in cells, and then counting the number that the bees uncap and remove. The two tests do not check for the same behavior. Bees can have one or the other traits, or they may have both traits, they can be hygienic and have Varroa sensitive hygiene.
