Cotton is an important crop in the USA, as is the in-plant protection from insect pests afforded by genetic engineering. This aerial photograph of a 3-acre cotton field demonstration shows what happens when uniform distribution of bollworm eggs results in differential larval survival and injury to areas without technology - spelling "Tigers".
"This aerial photograph illustrates the spelling ability of a researcher with a planter and two cotton varieties, the eating ability of bollworm, a major pest of cotton production, and the effectiveness of transgenic cotton technology on controlling bollworm.
Insecticidal proteins are produced by transgenic Bt cotton without the need for repetitive applications of foliar insecticides, making the GMO extremely environmentally friendly and economical for producers. Our demonstration under extreme pressure from bollworm clearly shows the value of the technology. A part of my research program evaluates these technologies and provides unbiased information for our producers. "
