Tampa St. Petersburg, FL, July 21, 2026 —

A new invasive insect, identified as the pasture mealybug, has been detected in Polk County, Florida, posing a significant threat to local ranches by damaging essential grazing grasses for cattle.

The pasture mealybug is not new to Florida, having already established its presence in 16 other counties across the state. Its latest confirmed location in Polk County raises concerns among ranchers about the potential for widespread damage to pasturelands, which are crucial for livestock. The insect operates by injecting a toxin into the grasses it infests. This toxin can lead to the death of the grazing grasses, directly impacting the available food source for cattle.

The consequences for ranchers can be substantial, leading to significant financial losses due to reduced herd health and the potential need for costly interventions to manage the infestation and restore damaged pastures. The full extent of the damage and the specific financial impact on Polk County ranches are still being assessed.

Further details regarding the timeline of the infestation in Polk County or specific mitigation efforts underway were not immediately available. The presence of the pasture mealybug underscores ongoing challenges faced by Florida’s agricultural sector in managing invasive species that can disrupt ecosystems and economic stability.
