How do billbug larvae primarily affect turf?

Billbug larvae primarily affect turf by feeding on the roots of the grass plants. Their feeding habits cause significant damage as they sever the roots, leading to poor nutrient and water uptake. This root damage can result in thinning of the turf and increased susceptibility to drought and disease, severely impacting the health and appearance of the lawn.

In addition to root feeding, they may also feed on other parts of the plant, but the primary concern is their impact on root systems, which is crucial for the overall health and sustainability of turf grasses. Understanding this feeding behavior is essential for managing the effects of billbug infestations in turf management strategies.
