FIEBERIELLA FLORII (STÅL), A VECTOR OF APPLE PROLIFERATION AGENT |
| Authors: | G. Krczal, H. Krczal, L. Kunze |
| Abstract:
When testing different leafhopper species from MLO-free leafhopper cultures, it was possible to transmit the apple proliferation agent with Fieberiella florii (Stål) from apple to apple ("Golden Delicious") under field conditions. Test plants developed symptoms 3 years after the beginning of the experiment. When injecting leafhoppers with MLO-containing insect inocula, F. florii transmitted the pathogen to celery. The plant showed symptoms after 18 weeks. Injection of insects with plant inocula did not result in a transmission of the proliferation agent. | |
