This question is very interesting to me also. I've got a pack of "Happy
Hive Salts" from Bickerstaffes Honey LTD recently and I gave the salt to Dr.
Amsiejus. His undergraduate student will start the efficiency investigations
this spring.
I have read an article on the Cupric gluconate efficiency and found that the
efficiency was only some 75 %. A mind stroke to my head. The efficiency of
accaricides is much higher but the survived mites get used to it in a few
years. What about a new line of mites got used to Cupric salts?
Any suggestions?
