From: "James W. Hock" " I've received several e-mail off BEE-L about sugar

I am sorry there were no comments ON list. Quoting the NZ 'Control of
Varroa' page 50 'sugar dusting has been researched in Finland and shown to
knock down 47 -56 as many mites as fell naturally. 15gms of super-fine
sugar was dusted between combs in 2-storey hives. Best results with repeats
every 2 days - can be used at any time of year'. It does not seem to be a
sole means of control, but if it knocks down mites without risks to bees ,
then why not dust every time the hive is opened for other reasons? It would
only take a minute. Could support biotech methods such as brood removal.
James is bringing his experience with simple bulb dusters to our attention.
Thank you. Please do report results next year.
