Scientists have developed Bt toxins for the management of Bt resistance in European corn borer and other crop pests.

Transgenic corn's resistance to pests has benefitted even non-transgenic corn, a new study led by scientists from the University of Minnesota shows.

Widespread planting of genetically modified Bt corn throughout the Upper Midwest has suppressed populations of the European corn borer, a major insect pest of corn, with the majority of the economic benefits going to growers who do not plant Bt corn.

Transgenic corn's suppression of the European corn borer has saved Midwest farmers billions of dollars in the past decade, reports a new study in Science.

A group of agricultural scientists reported in today's issue of the journal Science that corn that has been genetically engineered to produce insect-killing proteins isolated from the soil bacterium Bacillus thuringiensis (Bt) provides significant economic benefits even to neighboring farmers who grow non-transgenic varieties of corn.
