Abstract
This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.
The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.
Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they normally do not cause serious damage to sorghum, and controls for them are rarely justified in Nebraska.
