EXCERPT:

A final behavioural characteristic, the possibility that worker cell
size was responsible for the observed  tolerance in Africanized and
African honeybees caused great excitement in beekeeping circles with
beekeepers in Europe, USA and New Zealand producing African-bee sized
foundation on which to  keep their bees. African worker cells are
approximately 4.7mm in diameter, compared with 5.1mm for  European
bees.

The idea was that these African cells did not have enough room for
varroa mites to  reproduce, and originated with Message & Concalves
(1995) who reported lower varroa reproduction  and lower varroa
infestation in the smaller Africanized cells. Medina & Martin  (1999)
also found  increased varroa offspring mortality in worker cells of
Africanized bees, compared to European bees,  and suggested this was
because of the reduced cell size of African bees.

However, none of the early  studies separated cell size with other
African (or Africanized) characteristics, such as a shorter post-
capping period. More recent studies (e.g Taylor 2005), using only
European bees but with different cell  sizes, has shown that smaller
cells do not limit mite infestation or mite reproduction, and that
smaller cells might actually increase varroa infestation rates.

I have had that one for a while. It is an interesting report.

There has been discussion about doing one year studies with small cell. A lot of people feel that the bees need more than one year to acclimate themselves. (Am I saying that right?)

How long was Jenefer Beries test -bees live 6 weeks -might need a year to crash a hive? should get perspective before that  Undecided RDY-B

Interesting!!!.....

I found the Taylor work on beesource and recognised it.
It's the bad New Zealand test worth nothing, in which
different pieces of cellsize wax foundation were put into
LC bees and drawn and brooded.
...

Knowing that the mites go into different size cells by
order of size and royal jelly trigger for JGH, funny in a
way!..........

But then what do I know at my age!
