This may be a "how many angels..." subject.

Looking through some of the discussion of neonics, the term "sub-lethal"
dose appears.It is generally used to say that the dose is very small but
still has some effect on the bee or larva.

If you look at the actual meaning of sub-lethal, it is anything below
LD100. Some like to call it anything below LD50 but that is incorrect and
generally not a good use of the term.

It would be nice if those who conduct such studies or make such statements
actually note the found LD, for example LD10 or such.Then we would know
that some bees do die. However, in many of the studies, no bees die, but
there is an "effect".

When you look at all the stuff found in the two studies it sort of makes
looking at exceptionally low doses of pesticides pale compared to the much
higher doses found.
