Leek Moth
Scientific Name
Acrolepiopsis assectella
Description
Leek Moths are small moths whose larvae feed on leeks, garlic, and related alliums. Their presence is marked by serpentine mines in the leaves and overall reduction in plant vigor.
Characteristics
These moths are modest in size and coloration, while their larvae create winding, silvery trails on foliage. The damage disrupts photosynthesis and can significantly lower yields in allium crops.
Control Methods
- Organic sprays: Apply neem oil or insecticidal soap during peak larval activity to control infestations organically.
- Cultural practices: Practice crop rotation and promptly remove infected plant debris to break the pest’s life cycle.
- Preventive methods: Monitor allium crops early and maintain proper spacing and sanitation to reduce larval habitats.
- Biological controls: Encourage natural enemies such as parasitic wasps and insectivorous birds that target leek moth larvae.
- Mechanical physical: Utilize floating row covers to prevent adult moths from laying eggs, and hand-pick larvae when observed.
Natural Enemies
- Parasitic Wasps
- Insectivorous Birds
