Insect scientists say federal regulators need to take action against a growing pest problem in biotech corn.
They say corn rootworm has started to become resistant to Monsanto's Bt corn, which is genetically engineered to resist the damaging and costly pest.
The 22 scientists expressed their concerns in a letter sent to EPA earlier this week.
University of Illinois insect behaviorist Joseph Spencer was one of them.
The National Science Foundation has awarded a local researcher $1.3 million to study the genetics of how corn plants take up nutrients.
The ultimate goal is to reduce the amount of fertilizer needed to grow the ubiquitous crop.
Ivan Baxter, a U.S. Department of Agriculture research scientist and assistant member at the Donald Danforth Plant Science Center, will lead the research.
