A new aphid pest has infested grain sorghum in South and East Texas, southern Oklahoma, eastern Mississippi, northeastern Mexico, and central, northeast, and southwest Louisiana. In 2013, large populations of sugarcane aphids (Melanaphis sacchari) developed on sorghum plants. They produced large amounts of honeydew, which choked combines and caused lost grain in northeast Texas and Louisiana. Growers lost up to 50 percent of grain sorghum yield in infested fields during 2013.
