There has just been a report published on the bee health of Apis mellifera
on Norfolk Island.  It is an island off east coast of Australia.  See

ure_Pest_and_Diseases_survey_2015.pdf 

They targeted 25 pests and pathogens and only found lesser wax moth, Nosema
ceranae and Lake Sinai 1 virus.

 

I have been wondering for a while now how long N. ceranae has been around in
the A. mellifera population.  Norfolk Island has not had any introductions
of live mellifera for many years so the ceranae must have been introduced a
while back.  What is the earliest date that anyone has for when ceranae was
found in mellifera?  I remember reading somewhere that ceranae has been
found in stored samples in the USA from the early 1990's.
