"cutworm"の定義と意味

What is a "cutworm"?

A cutworm is a common pest that belongs to the larvae stage of various moth species. These caterpillars are known for their habit of cutting through the stems of young plants, hence the name "cutworm." They primarily feed on the stems and foliage of a wide range of crops, including vegetables, fruits, and ornamental plants. Cutworms are nocturnal and tend to hide in the soil during the day, emerging at night to feed on plants. Their feeding can cause severe damage to young seedlings, often resulting in the complete destruction of the plant. Controlling cutworm populations typically involves preventive measures such as crop rotation, using physical barriers, and applying appropriate insecticides.
