RESISTANT or IMMUNE to DAMAGE from 

 fuchsia gall mite (Aculops fuchsiae-Keifer)

 

                Growing fuchsias highly resistant to fuchsia mite (DAMAGE)…completely negates the need for spraying.

                                                                                                 Carlton Koehler, Entomologist,

                                                                                                 University of California at Berkeley, 1985

The following information has been gathered from the American Fuchsia  Society, Dr. Peter Baye  (San Francisco Botanical Garden/Strybing Arboretum), Mary Cooke (Redwood City), Regine Plows (1998- Ft. Bragg), Marjorie Wickham (1985- Mill Valley) and other AFS sources in California. Both Peter Baye and Mary Cooke currently maintain a mite garden to test resistance.  Previously, Regine Plows and Margaret Wickham had used microscopes to detect mites and compare their numbers to the severity of the damage.  They found mites on some plants that showed no symptoms of mites.  (In other words, with the mites there and no symptoms, the resistance is really to the damage, not the mites themselves.  Think of it as a "carrier" of some disease that does not seem to affect the host.)   From 1982-4, University of California entomologists formally tested plants’ resistance and response to various controls.  

This is not a complete list, and there are conflicting reports. Some fuchsias seem to be resistant in one garden but not in another.  Mites are transported passively and need insects, birds, wind or gardeners to move them around.  Because of this, even in the midst of a mite infected area, they may have never been exposed to mites. The following list will be updated and corrected as more information is gathered.

Along with information from PNW gardeners who have had fuchsia mite infestations, THE REALLY GOOD NEWS IS THAT it has been  found that the mites are killed when frozen (in the low 20's or teens for 6-8 hours) for 3-4 nights on hardy fuchsias outdoors all year.

KEY:

R= resistant.  Fuchsia gall mites will attack this plant, but damage is lessened to various degrees and at various stages in their growth pattern.  The ornamental value of the plant is retained.

I= immune.  Mites may be present but no galls are produced; little or no damage seen.
