Sequential evolution of resistance by western corn rootworm to multiple Bacillus thuringiensis traits in transgenic maize
Sequential evolution of resistance by western corn rootworm to multiple Bacillus thuringiensis traits in transgenic maize

Transgenic crops that produce insecticidal toxins derived from the bacterium Bacillus thuringiensis (Bt) are grown worldwide to manage insect pests. Western corn rootworm is a serious pest of maize in the United States and is managed with Bt maize. In the United States, the commercial cultivation of a Bt crop requires an accompanying resistance-management strategy to delay the evolution of Bt resistance.
