I suspect other studies have been carried out this summer
to address the question of whether or not there is a substantial difference
in the survivability of wild, unmanipulated monarch caterpillars developing 
on wild, unmanipulated milkweed plants growing within or near Bt corn 
fields vs. conventional corn fields. 

Yesturday, when a reporter asked Steve Johnson, a US Environmental 
Protection Agency deputy assistant administrator to comment on the Iowa
State study he said:

``Based on what we've seen so far, we're not seeing any impact on any
 non-target organism, particularly the Monarch butterfly''
