An anonymous reader writes "Though warned by scientists that overuse of a variety of corn engineered to be toxic to corn rootworms would eventually breed rootworms with resistance to its engineered toxicity, the agricultural industry went ahead and overused the corn anyway with little EPA intervention. The corn was planted in 1996. The first reports of rootworm resistance were officially documented in 2011, though agricultural scientists weren't allowed by seed companies to study the engineered corn until 2010. Now, a recent study has clearly shown how the rootworms have successfully adapted to the engineered corn. The corn's continued over-use is predicted, given current trends, and as resistance eventually spreads to the whole rootworm population, farmers will be forced to start using pesticides once more, thus negating the economic benefits of the engineered corn. 'Rootworm resistance was expected from the outset, but the Bt seed industry, seeking to maximize short-term profits, ignored outside scientists.'"
