Hi Allen.
It is good to hear from you too.
Thanks for your comments and explanation of SMR bees. It sounds like such a
tremendous development in the fight against varroa!  I have to see if I can
contact that research group in
Mexico to see if they have/can connect SMR bees with pheromone responses.
   I am traveling constantly these days, so it might take me a while before I
receive a reply to my query. I promise that I will post it to the list when/and
if I receive an answer.
Best regards.
