Answer: (A)

Billbugs are turf pests whose larvae feed on grass roots, so knowing which grasses they attack helps you predict where problems may show up. In eastern and southern Kansas, zoysiagrass is a known host, and there are also reports of billbugs infesting bermudagrass and bluegrass. This shows a broader host range in that region, including a warm-season grass (zoysia and bermuda) and a cool-season grass (bluegrass) when conditions allow. Because of this, the grasses billbugs may infest include all three listed: zoysiagrass, bermudagrass, and bluegrass. The other options omit grasses that have been documented as hosts, which is why they’re not as accurate in this context. If you see suspicious turf damage in those grasses in eastern or southern Kansas, consider billbug activity as a likely cause and proceed with appropriate monitoring and management.
