Fuchsia Gall mite [Aculops fuchsiae] is a microscopic sap sucking mite of Fuchsia plants grown both outdoors and in greenhouses. It may have been imported into the UK from the USA by accident but is now an increasingly common and damaging pest of Fuchsia plants.
The mite is very difficult to see without a microscobe, so it is more the damage symptoms that will indicate its presence. Growth at the shoot tips of plants are often swollen and distorted and may look yellowish and reddish. Flowers may also be deformed and may even fail to develop. The mite is a sap sucker and the chemicals they secrete causes galling, distortion and yellowing.
How to control and prevent Fuchsia mite damage
If Fuchsia gall mite is suspected on plants, prune the ends of the plants to remove the mites. For very heavily infested plants it maybe better to remove and destroy to prevent the spread to healthy plants. There are no garden insecticides that can be applied. However there is a biological control available with the predator Amblyseius andersoni .This predatory mite can be applied to Fuchsias to feed on and consume the gall mite, it is more efficient as a preventative and low infestation control, so should be applied early and on a regular basis.
