many trials in different countries [with beekeepers, universities and

PB:
Did anybody else notice this? Max writes "average 93%, sometimes lower".
What is this supposed to mean? Has he ditched the lower figures to keep from
lowering the average?

I have read at least a dozen papers on thymol so far and the effectiveness
seems to range from 50% to 98% mite kill.

There are many references to heavy bee mortality. One study said colonies
treated with thymol in the fall had 3/4 less brood in April, though they had
"caught up" by May.

Now the term 3/4 less is vague; I would rather read 25% as much brood, if
that is what they mean. But if you have pollination contracts in April --
having your hives at 2 comb strength instead of 8 could be a real problem.

I want to know if these problems have been worked out.
