We have been working with Dr.Nasr and the Ontario Breeding program for a
number of years now. They can tell us wether our strain of bees are
resistant or tolerant to T-mites, but not a word about the mechanisms. It
has been known, for a long time, that the mature mite moves out and looks
for a new host under 4 days old. Beyond that, nothing.
        It is thought that the mites don't like the taste of the new host and
move back out, as there is record of bite marks in some tracheae but no
mites.
