Have been thinking about unexplored treatment methodologies. Given the 
similarity of the tracheal and Varroa mites and bees (all insects), 
treatments would seem have a difficult time with targeting. Chemicals 
are proving difficult. Hormonal or genetics of course might yield future 
fruit.

Given the size difference, I'm curious if a high intensity acoustic 
bombardment at a high enough (ultrasonic) frequency might affect mites, 
but be small enough in wavelength to be non-detrimental to the larger 
honeybee.

Any thoughts on this? ( I did see some work with pine bark beetles).
