Cutworms
Scientific Name
Noctuidae
Description
Cutworms are the larval stage of moths that sever young seedlings at the soil line. They are most active at night and can cause significant damage to emerging plants.
Characteristics
These robust, hairy caterpillars are typically brown or gray. Their nocturnal feeding makes them hard to detect until significant damage has been done.
Control Methods
- Organic sprays: Apply neem oil or insecticidal soap during early infestation periods to minimize damage.
- Cultural practices: Practice crop rotation and remove plant debris that may harbor cutworms.
- Preventive methods: Keep garden beds clean and use protective collars around seedlings to deter cutworm feeding.
- Biological controls: Promote natural predators such as ground beetles, birds, and parasitic wasps that feed on cutworms.
- Mechanical physical: Hand-pick cutworms during the evening and use physical barriers like seedling collars.
Natural Enemies
- Ground Beetles
- Birds
- Parasitic Wasps
