Blackberry Psyllid on Brambles
Return to Insects and Other Arthropod Pests
Blackberry psyllid (Trioza tripunctata) is a tiny 1/12- to 1/8-inch long insect and feeds with piercing-sucking mouthparts. Feeding causes distorted, compact growth. Nymphs also contribute to leaf distortion and feed inside curled leaves. Blackberry psyllid overwinters on nearby coniferous trees and migrates to brambles in May.

Management:
- Avoid planting brambles within 250 yards of conifer plantings.
- Apply insecticide when psyllids are present.
