Feltia moth

The genus Feltia belongs to the family Noctuidae (order Lepidoptera). These insects are commonly referred to as surface-feeding cutworms, known for their soil-dwelling larvae that pose a significant threat to agricultural production worldwide.

Feltia species are polyphagous, attacking a wide range of crops including corn, sugar beets, sunflower, potatoes, and various vegetables. Their larvae thrive on young plant tissue, often targeting seedlings just after emergence, which leads to substantial stand loss.

The life cycle consists of four stages: egg, larva, pupa, and adult. Typically, these insects overwinter as larvae in the soil. Upon warming in the spring, larvae resume feeding activity, often migrating between plants at night. Multiple generations can occur depending on the specific species and climatic conditions.

The damage is particularly severe because the larvae bite through the stems at or just below the soil surface, causing the plants to topple over and wilt rapidly. This cutting behavior, which gives them the name "cutworm," makes them especially damaging to young, vulnerable crops during the early establishment phase.

• Implement deep fall tillage to expose larvae and pupae to predators.
• Maintain weed-free fields to reduce egg-laying sites for adults.
• Utilize pheromone traps to monitor adult flight and predict infestation levels.
• Apply targeted insecticides when larval populations exceed economic thresholds.
• Encourage natural enemies such as ground beetles and parasitic wasps.
