Hidden in the soil of Illinois and Iowa, a new generation of insect larvae appears to be munching happily on the roots of genetically engineered corn, according to scientists. It's bad news for corn farmers, who paid extra money for this line of corn, counting on the power of its inserted genes to kill those pests. It's also bad news for the biotech company Monsanto, which inserted the larvae-killing gene in the first place.
In fact, the gene's apparent failure, as reported in the journal PLoS One, may be the most serious threat to a genetically modified crop in the U.S. since farmers first started growing them 15 years ago. The economic impact could be "huge," says the University of Arizona's Bruce Tabashnik, one of the country's top experts on the adaptation of insects to genetically engineered crops. Billions of dollars are at stake.
The story of how this happened is long and complicated, but the details are important, so let's start at the beginning.
