This is an interesting article, and rather unsettling. It's potential
use in class extends far beyond the authors' intent. The article
describes the rapid adoption of certain genetically engineered crops.
supported by a large resarch and development effort in China. Their
primary example of a success is cotton bollworm. They describe how the
Chinese cotton industry did a poor job of resistance management with
insecticides and have now deployed Bt cotton in its place. If it is used
with the same management practices, they will soon have cotton bollworm
that is resistant to Bt as well as the previously-used insecticides.
That is the ecologists and the crop manger's concern about engineered Bt
crops. The nature of resistance management is a great teaching tool for
ecology that engages students in a current high-visibility problem.
What is unsettling about this article is that the authors don't even
acknowledge this well-known risk or the cost to industry that it
represents. It is as if they figure their profit before all the bills
have arrived. Papers like this one keep serious people questioning the
ability of the agbiotech industry to self-regulate. As an academic
scientist, I am annoyed at getting tarred by the same brush. Scientists
can produce some great technology, so it's a shame to see it misused.
