Sugarcane Aphids Numbers Still Here
With 8 locations for sugarcane aphid monitoring levels in the early start of the planting year were low. As the season progressed aphids grew in numbers. A late-season, food-grade sorghum plot I had in Oxford was devastated by sugarcane aphids. The early season varieties took the worst hit. The later season varieties seem to fair better in numbers and damage. Planting early season varieties late in the year may be problematic and have high numbers. I monitored sugarcane aphids in grain sorghum, johnson grass, miscanthus, shatter cane, and other cane-type plants. Sugarcane aphids are an invasive species and came from Mexico spread all the way north to North Carolina. Monitoring is necessary to see what hosts and other crops can be affected by the invasive species.
