Leafrollers
Scientific Name
Tortricidae
Description
Leafrollers are caterpillars that roll or fold leaves to create a sheltered feeding site. They are commonly found on fruit trees and shrubs, and their rolled leaves are a clear sign of infestation.
Characteristics
Typically small and green or brown, these larvae use silk to roll leaves. Their feeding damages the leaf structure and reduces photosynthetic capacity, weakening the plant over time.
Control Methods
- Organic sprays: Apply neem oil or insecticidal soap during early infestation to disrupt larval development.
- Cultural practices: Practice crop rotation and remove rolled leaves to eliminate larval hiding places.
- Preventive methods: Maintain vigorous plant health with proper watering and balanced fertilization, and inspect plants regularly for early signs of leaf rolling.
- Biological controls: Encourage natural predators such as parasitic wasps, lacewings, and predatory beetles that target leafroller larvae.
- Mechanical physical: Hand-pick larvae when possible and use row covers during peak periods to prevent adult moths from laying eggs.
Natural Enemies
- Parasitic Wasps
- Lacewings
- Predatory Beetles
