Mealy Infestation

This Gordo bluestem pasture in Matagorda County shows the effects of a pasture mealybug (Heliococcus summervillei) infestation. The reddish-brown discoloration, thinning stand density, and reduced plant vigor are common symptoms associated with pasture dieback. These sap-feeding insects attack grasses at the base of the plant, weakening growth, reducing forage production, and, in severe cases, causing widespread stand loss.

Pasture mealybugs have become an increasing concern across Texas, impacting bluestem species, Tifton bermudagrass, and other improved pasture grasses. According to Texas A&M AgriLife Extension, infestations have spread across numerous counties and can significantly reduce grazing and hay production, making monitoring and early detection critical for producers.

Wildlife Habitat Federation can assist landowners by evaluating pasture conditions, identifying resource concerns, developing grazing management strategies, and creating restoration plans that improve pasture resilience and help recover productivity following insect damage.
