Pasture mealybug confirmed in Georgia agriculture

Georgia Agriculture Commissioner Tyler J Harper has announced the first confirmed detection of the pasture mealybug (Heliococcus summervillei) in the state. The invasive insect was confirmed by the U.S. Department of Agriculture on August 5, 2026, in Decatur County, Georgia, after being identified at a turf grass business.

The pasture mealybug poses a significant threat to agriculture by feeding on plant sap and injecting toxic saliva, which can cause yellowing leaves, purple or red discoloration, stunted growth, and poorly developed roots. The pest primarily affects annual and perennial warm-season grasses and can spread rapidly through equipment, clothing, and vehicles.

This detection follows recent sightings of the insect in Texas, Florida, and Louisiana. Officials are urging farmers to maintain strict biosecurity measures, such as cleaning farm equipment between fields and changing clothing and footwear, to prevent further spread. Farmers suspecting an infestation are encouraged to contact their local County Extension Agent immediately.
