We may have a new insect pest to manage in cotton fields next year (2026). The Cotton Jassid, Amrasca biguttula Ishida (also known as the two-spot cotton leafhopper) was found in hibiscus plants in big box store nurseries across the state in the past month. There has also been a probable detection in a cotton field in Wharton County, but this is awaiting confirmation.

Hopefully this insect will not become established in Texas, but it is best to be aware and prepared for the possibility.

Adult cotton jassids measure approximately 1/8 of an inch (2-3 mm) in length and are pale green with yellowish-green wings. They can be distinguished from other leafhopper species by a prominent black spot on the apical area of each forewing and, often, by two dark spots on either side of the head. Nymphs are very small, less than 1 mm.

Nymphs and adults feed on the undersides of leaves, extracting sap with their piercing-sucking mouthparts and causing curling, yellowing, and bronzing of foliage—symptoms collectively referred to as
“hopperburn.”

Based on the initial studies done in Alabama and Georgia, the recommended treatment threshold for cotton jassid is one to two nymphs per leaf.

Although insecticide efficacy evaluations are ongoing, Bidrin, Sivanto Prime, Sefina, and Carbine have shown promise in Georgia and Alabama.
