Good Morning and a Happy Thanksgiving to all.

Why is it that Ohau has now found varroa mites in 2007 when in fact they 
have been devastating honey bees across America since 1987?  How have the 
beekeepers on that island managed to DELAY the advent of mites for as long 
as twenty years?  

Was the secret a tight regulation or free movement?  (For imports, I am 
all for microscopic sampling at the port of entry, not mere a visual 
inspection)  Or could it be their geographic isolation that has disallowed 
migratory mite-infected bees in the vicinity?  

Is this evidence not hard enough?
