Have you heard anything? BTW, it is Bil who posted the link.

I am interested as I would like to know how they measured that picogram of
Imid.

There is a bit of confusion in the post with ppt and a picogram being
equivalent. Ppt is the basis of Bil's argument that levels cannot be
detected easily. But the bees were fed one picogram. They are different
measurements. One is a ratio (ppt) and the other a measurement of mass
(picogram).

If you feed one picogram as a pure sample it would be 1:1 (one trillion
parts per trillion). But if they diluted a larger sample, which seems to be
the way to go as most labs do not have a 1 picogram measuring spoon, then it
could be ppb, ppm or anything, hence measurable. It seems unlikely to be a
ppt solution as it would require feeding more than the bee's stomach could
hold to get a picogram into the bee. Higher concentrations would do it, but
then they would be easily measurable. Which was my point being disputed by
Bil.

Very confusing. Need the paper to sort it out.
