Yes, certain types of worms, specifically the larvae of the corn earworm, can eat corn silk.
Corn Earworms and Corn Silk
The primary insect pest that targets sweet corn is the corn earworm. According to the National Agricultural Library, the larvae of the corn earworm, often referred to as "worms," hatch from eggs typically laid on the corn silks. These larvae then feed on the silk itself.
Feeding Habits of Corn Earworms
Here's a breakdown of how corn earworms consume corn silk:
- Egg Laying: The adult corn earworm moth lays its eggs directly on the corn silk.
- Hatching: Once the eggs hatch, the larvae (worms) emerge.
- Feeding on Silk: The newly hatched larvae immediately begin to feed on the corn silk.
- Burrowing: As they feed, they burrow through the silk mass towards the corn kernels.
- Kernel Consumption: If left unchecked, they will also devour the kernels themselves, causing significant damage to the corn ear.
Impact of Worms Eating Corn Silk
The consumption of corn silk by corn earworms can have negative consequences for corn production:
- Reduced Yield: Kernel damage reduces the overall yield of the corn crop.
- Quality Degradation: Damaged kernels lower the quality and market value of the corn.
