Hello All
These questions are for my American beekeeping colleagues.
In what year was varroa first found in the USA?
In what year was resistance to Apistan/Bayvarol first reported?
In what year was resistance to Coumaphos first reported?
I shall be most grateful for this information, as I am updating one of my
lectures and need to have the update in place in the next 10 days or so.
Thanks indeed for help
Sincerely
Tom Barrett
