In 2013, the sugarcane aphid, Melanaphis sacchari, was discovered damaging sorghum near Beaumont, TX. The aphid was confirmed on sorghum from 30 counties in LA and TX, and one county each in OK and MS by the end of the 2013 sorghum-production season. In 2014, the aphid expanded its range to 12 states and more than 300 counties. In the current year, the aphid continues to spread in range. The sugarcane aphid is a semi-tropical species that requires a living host to overwinter. The aphid has a short life-cycle and tremendous reproductive capacity. Sorghum yield loss occurs when large sugarcane aphid populations remove plant sap and honeydew accumulations interfere with harvest. This presentation will provide information on sugarcane aphid identification using key morphological characteristics important to separate the aphid from others frequently found on sorghum. Participants will gain knowledge of sugarcane aphid biology and damage to sorghum. Topics also will include important IPM practices to manage the aphid such as economic thresholds, biological control, plant resistance, and insecticide evaluations.
