<<Briefly, 5 rectangular pieces of comb 5 cm x 8 cm with cells ranging in
size from 4.7 mm to 5.4 mm were inserted into the same brood combs, and
after three generations of brood were frozen and the number of infested
cells and the number of adults and offspring per cell were counted. A
total of 1,616 cells were assessed from 10 nucleus colonies, 2 frames
per colony.
Robert Dartington asked if the bees uncapped more infested cells of
small size. The study doesn't address this point.
Trevor Weatherhead is correct in that 4.7 and 4.8 mm foundation was
inconsistently drawn out. However, the author says that "enough sections
(of comb) with correctly shaped cells were obtained for trial usage".>>
The only thing this study appears to test is whether varroa are less likely
to enter and breed in smaller cell. It says nothing, as far as I can see,
about what would happen in hives (rather than patches of comb) with different
sized cells, or whether the brood raised in smaller cells has an equal chance
of reaching adulthood and breeding successfully.
