This is from Beeinformed (West Australia) April 2009 (which also contains
an article about Peter Detcheon).
I searched the Archives, but didn't find any reference.
Does anyone have more info on "Empty Nest Disease" in China?
Randy Oliver
China is experiencing two new bee
diseases, ‘Empty Nest Disease’ discovered
and named in 2006 by Chen Yuan and
‘Crawling Bee’ discovered in 2003.
Colonies all over the country have been
decimated.
‘Empty Bee’ disease can reduce a strong
swarm of Italian honeybees into a few
worker bees and a queen within two to
three weeks.
Researcher Chen Yuan found bees of
all ages crawling on the ground outside
their hives in October 2006. Some were
normally developed and some had curved
wings. In some hives, he found the queen
and dozens of bees crawling helplessly on
small blocks of comb with pupae.
The cause of the disease is thought to be
fungal and is treatable with Ketoconazole,
a broad spectrum fungicide.
In 2003, China experienced a collapse
in the number of bee colonies due to
‘Crawling Bee Disease’ and this has
worsened every year.
