About Sugarcane Aphid
The sugarcane aphid (Melanaphis sacchari) is a 1–2 mm yellowish-to-olive aphid that became a devastating pest of grain sorghum in the United States after its first detection in Louisiana in 2013, spreading to 23 states within two years. Colonies build up explosively on the undersides of lower leaves, reaching thousands of aphids per plant within weeks, causing yellowing, leaf die-off, and honeydew accumulation that gums up harvesting equipment. Natural enemies including lacewings and parasitic wasps can suppress populations when insecticides are used judiciously, making threshold-based scouting essential before any treatment decision.
