Aptly named for their bright lime color, greenbugs (Schizaphis graminum) have been a major vexation for growers of wheat and sorghum for more than half a century, especially in the Great Plains. As decades of research into the little aphids have accumulated, the time has come for an overview of the little aphid and a summary of control methods, according to Dr. Tom Royer, professor and IPM coordinator at Oklahoma State University. He is the lead author of a new paper on these insects in the open-access Journal of Integrated Pest Management.
