The main observation in the experiment IMO is that feeding BT
fortified substrate (10ppm) to larvae, re-selected to yield high Bt
resistance (LC50~200 ppm), increased their mean pupae weight
significantly - about 20% - relative to feeding them non-BT fortified
substrate -- while leaving their time to pupation unchanged or perhaps
a bit shorter.

Has the experiment been replicated?


I don't know, Jack. You can ask the authors if they are working on
that or something similar, email: h dot cerda at ic dot ac dot uk


So how are you placing so much weight on this paper as to dismiss out
of hand Oz's hypothesis? snip


I already explained why I think Oz's hypothesis as to what caused the
observed difference is untenable. Look back the thread.
