What's eating my saintpaulia 'ness' dipity'?

Saintpaulia 'Ness' Dipity' is an indoor African violet cultivar prized by collectors. African violets are prone to cyclamen mites — the number-one pest across the genus — as well as mealybugs in the crown and thrips on flowers. Good quarantine practice when acquiring new plants is the most effective prevention.

Centre leaves curl inward, become stiff, misshapen, and lighter in colour; flowers deform; plant looks like it has a disease. Remove and destroy badly affected plants; treat the remainder with abamectin-based miticide; never share tools between plants without sterilising.

Cottony white specks in leaf axils and beneath leaves; sticky honeydew encourages black sooty mould. Dab with 70% isopropyl alcohol; follow with weekly neem oil sprays; keep infected plants quarantined.

Pale streaks and brown marks on petals; flowers fail to open properly; tiny insects visible under a hand lens. Remove affected flowers promptly; spray spinosad or insecticidal soap weekly; use blue sticky traps to detect and monitor.
