Dear all;
I was following your discussion, however, I was too busy to answer
them sooner.

Dave read it right. The title of my PhD thesis is " Detection of
major mite pests of Apis mellifera and development of non-chemical
control of varroasis". In my detection method I did not use powdery
sugar, as my method have higher detection efficiency, for more
information see

OTC is toxic not only to brood, but to bees also. Hence, it is
recommended to dissolve the OTC to 4 -5 litter of sugar when
possible.

Yes, there is no adverse effect on colony growth. So
it can not be fetal to open brood. I have published the effect of
dusting on colony growth in my dissertation that consists of eight
articles and the thesis, a total of 110 pages. Two dozen of this
book are available for the most interested beekeepers/ scientific
library for 15 $ (fifteen USD Airmail included). You may send your
request to me directly till the end of this month. During June I will
not be available.
Best regards
Kamran
