Sugarcane aphids first were reported in Kansas on July 25 in a commercial field in Sumner County.

From Aug. 15 to 20, new reports were positive for sugarcane aphid in Finney, Ellis, Sedgwick, Haskell and Ford counties, according to Extension entomologists. Reported aphid densities are well below threshold, but those with sorghum fields in the above listed counties and surrounding counties are encouraged to scout fields now. If found, continue to scout as populations can change quickly.

Below is the “KSU Sugarcane Aphid Scout Card” that can be found on the myfields website to assist producers in scouting and decision making.

Report all new infestations by contacting your local county Extension agent. For users, submit reports using the Pest Sampler module ( and someone will be in contact with you to confirm.
