The pasture mealybug is a new invasive insect pest that has recently been detected in Florida and is causing concern for pasture, hay, turfgrass, and sugarcane producers. Real-time updates can be found on the UF/IFAS Extension Forage Team's Pasture Mealybug page.

The pasture mealybug (Heliococcus summervillei Brookes) is a grass-specialist insect pest (Hemiptera: Coccomorpha: Pseudococcidae) recently found in Florida that can be problematic for pastures, hayfields, sod production, turfgrass, and sugarcane. As of June 19th, 2026, surveys have confirmed the mealybug in fifteen Florida counties including: Brevard, Charlotte, Collier, Glades, Hardee, Hendry, Highlands, Indian River, Lee, Martin, Okeechobee, Osceola, Palm Beach, Polk, and St. Lucie. The most damage has been observed on limpograss and sugarcane, but several other grass species are being affected, including bahiagrass and bermudagrass.

Pasture Mealybug: A New Threat for Pasture Grass, Turfgrass, and Sugarcane in Florida

Erin Powell, Isaac L. Esquivel, Nicole Quinn, Marcelo Wallau, Adam G. Dale, andBrent Sellers

The pasture mealybug (Heliococcus summervillei Brookes) (Hemiptera: Coccomorpha: Pseudococcidae), a pest now found in Florida, can cause severe dieback of grasses. It was first reported in the continental US in Texas in October 2025, though researchers suspect it arrived before 2022. In Texas, it was found on many grasses, including bermudagrass, bahiagrass, and johnsongrass. Along with pasture and turfgrass, it has emerged as an important pest of sugarcane, spreading from Texas to Louisiana. In Florida, it was first reported in late May 2026 on limpograss in the southeastern part of the state. As of June 19, 2026, surveys confirmed the mealybug in 15 Florida counties including: Brevard, Charlotte, Collier, Glades, Hardee, Hendry, Highlands, Indian River, Lee, Martin, Okeechobee, Osceola, Palm Beach, Polk, and St. Lucie. The most damage has been observed on limpograss and sugarcane, but several other grasses are affected, including bahiagrass and bermudagrass.
