How to Manage Pests

Pests in Gardens and Landscapes

Fuchsia gall mite—Aculops fuchsiae

Fuchsia gall mite was accidentally introduced from South America in the 1980s. They are microscopic wormlike mites and occur in growing tips year-round and in flowers during the blooming period.

Damage

The fuchsia gall mite causes leaves and shoots to become thickened and distorted, sometimes forming irregular galls. Because fuchsias grow best where summers are cool, this mite is a particular problem in coastal California.

Solutions

To reduce problems, plant only resistant fuchsias and consider replacing susceptible plants. Prune or pinch off and destroy infested terminals. If damage cannot be tolerated, pruning may be followed with two applications of a miticide, applied 2 to 3 weeks apart. Soap or oil sprays provide some control, but cannot kill fuchsia gall mites enclosed in distorted plant tissue. On highly susceptible varieties only, applications of acephate may help control mites.
