What type of environmental damage can sod webworms cause?

Sod webworms are notable pests primarily found in turfgrass and can cause significant damage by feeding on the grass blades and stems. The correct choice reflects that their feeding behavior leads to localized patches of dead grass, which is a direct consequence of their activity. These patches occur because sod webworms may consume large amounts of plant material, ultimately stunting growth and leading to the death of affected grass areas, particularly when infestations are high.

Overpopulation of grass species typically refers to the extensive growth of certain types of grass due to favorable conditions, not a direct effect of sod webworms. The enhancement of local insect populations varies and does not directly relate to sod webworms, as they are more likely to decrease the grass health that supports other insects. Similarly, an increase in soil nutrients would not be a result of sod webworm activity; in fact, their presence often indicates a decline in plant health rather than an improvement in soil quality. Understanding the specific impacts of sod webworms helps in managing them effectively to protect turf health.
