Bt in corn: Only Monarchs

[Michael Gochfeld]

I may have missed part of this BT thread, but why is it only Monarchs. 
The corn pollen containing BT (if it has significant amounts of BT) 
would fall on all sorts of leaves and kill all sorts of caterpillars. 

It's difficult to sort the vested wheat from the vested chaff. Cynics 
have said that a major outcome of the bioengineered BT, is to speed up 
the resistance of insects to BT, thereby wiping out "organic" farming 
which relies on BT---in case we don't have enough to worry about. It 
would be useful to hear from some of our more knowledgeable colleagues 
about how resistance to BT evoltes.
