The Maine Bee Inspector reported some time back that sugar rolls could
give incorrect results. As I recall, it was time/temperature dependent
so you could get indicators of no or few mites when there were actually
many. Follow up ether rolls on the same bees gave accurate drops. So I
would go down this route with caution.
