Which pests are considered aboveground and feed on turfgrass blades and stems?

• A. Sod webworms, armyworms, cutworms, and chinch bugs
• B. White grubs and billbugs
• C. Buffalograss pests only
• D. Nematodes and slugs

Answer: (A)

The main idea here is recognizing which turf pests feed on the grass from the surface, not from the soil. The pests listed in the correct option are all above the soil line and feed on the blades and stems of the turf, which is why they’re described as aboveground feeders. Sod webworms, armyworms, cutworms chew on the leaf tissue and stems of the turf, often creating ragged patches and visible chewed blades. Chinch bugs feed by sucking sap from the upper surface of the leaves, causing yellowing and stippling in the canopy. This surface feeding is the key trait that groups them together as aboveground pests. White grubs and billbugs, by contrast, live in the soil and feed on roots and crowns. Their damage shows up as thinning turf from below the surface, not from the leaf blades and stems, so they’re not considered aboveground feeders. Buffalograss pests is not a defined category of aboveground turf pests, and nematodes and slugs don’t fit the specific aboveground-feeding on blades/stems pattern as cleanly—their feeding is largely underground (nematodes) or not limited to the turf canopy (slugs can be surface feeders but aren’t the classic aboveground turf-feeding group described here). So, the group that fits the description best is those that feed on the turf canopy from above the ground line.
