Matilla and Harris did mark bees. It is very easy to do. Could you please
do so this fall and let us know the results?

Could very well be, Bill. Could be that a combination is necessary.

universal to all bees or are there significant innate genetic variations ?
Very likely. All, or nearly all, Calif breeders produce bees that build up
for almonds, so would be very interesting to compare strains. I've
observed that Russians are far more responsive to incoming pollen than are
Italian type.
Pete, your latest post is certainly food for thought. I'm out of country
on a consulting gig at the moment, and pushed for time, but will get back.
Thanks!
