research on caging queens and oxalic acid treatments?
I also found it to be a poorly designed experiment.
Below is my take on using induced brood break and OA to control varroa.
It's easy to do with homemade divider boards with queen excluder inserts
(search for "A home-made queen excluder division board" at

MITE CONTROL USING A 14-DAY BROOD BREAK WITH OXALIC DRIBBLE
•Day 1: Confine the queen to one “varroa trap” frame, using queen excluder
dividers.
•Day 14: Release the queen.
•Day 21: Remove the varroa trap frame and dribble the colony with oxalic
acid.
The above schedule is to make it easy to do on the same day of the week.
If there's a great deal of drone brood, you could increase to day 17 and 24
for slightly higher efficacy.
