What Australia says about chalkbrood
http://beeaware.org.au/archive-pest/chalkbrood/#ad-image-0
Chalkbrood disease is present throughout most of Australia and its incidence is generally higher when a colony is subject to temperature changes, particularly cooler weather, or other sources of stress.
Actually Auistralia does not know (the author) what to do with chalkbrood.
I read 15 years ago from MAAREC's disease booklet, that only way is change genes in apiary. And then I started change operation.
Australia knows hygienic queens but it does not know that there are immune stoks of bees. Two different things.
Well..... Most of Finnish beekeepers met serious problems with chalkbrood when varroa arrived. It is stronly varroa driven. Then guys have selected and bred queens so that it is OK now.
But if I buy new queens, I may get chalkbrood queens. But it is only a part of business. I squeze the queen and
My secret weapon is that I have spare queens in spring, and I change the queen if the colony has chalk brood mummies. And I change again, if the new is not immune.'
.
I think that varroa has pushed the chalkbrood to so serious level that you must do something to it.
.If the disease is mild, just live with it.
I remember that I had those mummies 50 years ago but thought that they are moulded pollen. Then the diesease bursted totally out 1990 when I started patty feeding.
