Sugarcane aphids are capable of very high rates of reproduction and produce copious amounts of honeydew. Scout early and often for the sugarcane aphid in sorghum.
Sugarcane aphids are found on the undersides of sorghum leaves. Leaves below infested ones will be covered in honey dew (aphid excretion) and will have a shiny appearance which become colonized with a sooty mold after a period of time.
Shiny honeydew on leaf is a easy way to detect these aphids (left). These leaves become colonized by sooty mold and shed skins of the larvae after a period of time (right).
There are several similar species on sorghum that could be confused with the sugarcane aphids especially when the aphids are young. The SCA has a smooth body with a light colored head and light colored legs with dark feet. They have dark colored, short cornicles (tail pipes) with no shading at the base of them as on the corn leaf aphid.

Timing effective control for SCA in sorghum depends on the size of the populations. To estimate the number of SCA and determine if management is needed in a field, follow the guidelines in our new Scouting Sugarcane Aphid guide.
