Phorodon cannabis Aphid
Overview
Phorodon cannabis aphid (commonly called cannabis aphid) is a specialist aphid species associated with cannabis and hemp production systems.
It is particularly relevant in:
- protected cannabis production
- medicinal cannabis systems
- hemp production
- indoor cultivation environments
The species can establish rapidly in dense protected canopies where environmental conditions remain stable.
Identification
Typical characteristics include:
- pale green aphids
- elongated body shape
- darker longitudinal striping
- colonies on stems and undersides of leaves
- honeydew production
Colonies may establish deep within dense canopies before becoming visible externally.
Crop symptoms
Typical symptoms include:
- reduced plant vigour
- sticky honeydew
- black sooty mould
- distorted growth
- contamination of flowers
- reduced crop quality
Heavy infestations may significantly affect marketability and harvest cleanliness.
Environmental drivers
Pressure is often favoured by:
- warm stable environments
- dense canopy structure
- reduced airflow
- continuous vegetative growth
- protected indoor systems

IPM considerations
Integrated Pest Management programmes should focus on:
- early scouting
- canopy inspection
- airflow management
- environmental stability
- hotspot mapping
- compatible biological control
- hygiene between crop cycles
Dense crops may hide developing colonies until populations become well established.
Biological control relevance
Potential biological control agents may include:
Programme performance depends heavily on early establishment and canopy penetration.
Monitoring strategy
Useful monitoring approaches include:
- underside leaf inspections
- hotspot scouting
- winged aphid observation
- canopy penetration checks
- edge monitoring
- environmental stress observation
Monitoring intervals may need shortening during warm rapid-growth periods.
