Sugarcane rootstock weevils are pests of which crop?

• A. Corn
• B. Cotton
• C. Sorghum
• D. Wheat

Answer: (C)

This question tests knowledge of which crops can serve as hosts for the sugarcane rootstock weevil. These weevils target the root crowns of grasses in the sugarcane family and are known to affect sugarcane and sorghum because both share similar root and crown structures that the insect can infest. The damage they cause at the root crown can stunt plants, cause wilting, and reduce stands, which is why sorghum is the best fit among the options. Corn, cotton, and wheat are not typical hosts for this pest, so they don’t fit as crops at risk from sugarcane rootstock weevils.
