It doesn't fit or explain anything at all, since the same cabbage leaf
material was fed in all treatment groups in the experiment. The
researchers grew a single cabbage crop, cut discs from its leaves, and
fed the discs to different groups of larvae kept in petri dishes, with
or without Bt toxin fortification.

What % DM was leaf and what BT in the two trials?
What was the protein level in the DM of the two feeds?

Were both groups fed ad-lib?

I if the former was under 1% or so and the latter true then I would want
to see independent verification.
