Entomologists advise EPA on resistant corn rootworms

Wisconsin entomologists sent a letter to the Environmental Protection Agency in early March advising them on how farmers should deal with corn rootworms that are building a resistance to transgenic corn. Transgenic corn contains a protein that is supposed to kill corn rootworms, but evidence indicates that rootworms are adapting to this threat.

Some suggestions for limiting or slowing the spread of resistant rootworms include planting some non-transgenic corn to promote the non-resistant rootworm population. This plan hinges on the idea that the non-resistant rootworms will then spread their genes to the rest of the rootworm population.

Farmers can also switch between different kinds of transgenic seeds.
