Some published paper claimed the ether roll and sugar roll (basically the
same, but no dead bees) were not reliable in predicting true mite levels in
hives. Overnight drop tests (with no drugs)  apparently were much better in
doing so.  And the roll tests don't use those tired old field bees -- you
need nurse bees for anything like reliable results (just don't scoop upthe
queen).

Is there a feeling against doing the ether roll?
