- Yellowing or chlorotic spotting
- Reduced vigour
- Honeydew contamination
- Colonies on soft growth and leaf undersides
Host relevance
Important in:
- protected ornamentals
- peppers
- tomatoes
- nursery crops
- soft growth crops

- young growth
- leaf undersides
- hotspots
- winged aphid movement
- beneficial establishment
Biological control relevance
