Which insect is noted as migrating slowly from east to west across Kansas?

• A. corn rootworm
• B. black cutworm
• C. Japanese beetle
• D. wireworm

Answer: (C)

Understanding how pests spread across a region helps predict where damage may appear next and guides monitoring and control efforts. The Japanese beetle is an invasive species that has slowly expanded its range from east to west across the United States. In Kansas, eastern populations established earlier, and over time the beetles have dispersed westward in waves as adults fly and colonize new areas. This slow, directional expansion is a known pattern for Japanese beetle populations, making it the best match for a question about east-to-west migration in Kansas. The other pests are tied more to local field conditions or short-distance movements rather than a gradual, state-wide westward spread.
