Apistan is used to see the level of infestation even in a previously resistant colony, and also with cumophose resistant mites. In fact, you can put in a Cumophose strip and get little drop and an Apistan strip and get good drop if the mites are resistant to both. It will probably be misleading to use the drop as an indicator of resistance in the colony. The key was posted by someone else who noted that you will get much less effectiveness from the strip, but you will get some control.
