Soybeans will soon contain built-in resistance to the exotic aphid, Aphis glycines, also known as the Chinese soybean aphid.

Scientists with the USDA-Agricultural Research Service have discovered a soybean gene that is resistant to Chinese soybean aphids. The exotic pest was first detected in Wisconsin in 2000 and quickly spread across the Midwest and South, leaving millions of dollars of damage in its wake. The cost of current control measures ranges from $12 to $25 per acre. New soybean cultivars bred to express the resistant gene could be available by 2008, say researchers.
