Fieberiella florii
privet leafhopper, Flor's leafhopper, cherry leafhopper
Fieberiella florii is a leafhopper species in the family Cicadellidae, native to Europe and established in North America. It is a phloem-feeding insect that develops on multiple woody host plants, particularly in stone fruit orchards and surrounding vegetation. The species has been experimentally confirmed as a vector of 'Candidatus Phytoplasma mali', the causal agent of apple proliferation disease. In western Oregon, it shows a distinct seasonal cycle with overwintering eggs, spring nymph emergence, and peak adult populations in summer.
Scaphytopius acutus
Sharp-nosed Leafhopper
Scaphytopius acutus is a leafhopper species in the family Cicadellidae, commonly known as the Sharp-nosed Leafhopper. It serves as a documented vector of Peach X-Disease, a phytoplasma pathogen affecting stone fruit cultivation. The species has been studied for its ecological role in bridging wild host plant reservoirs and cultivated peach orchards, with seasonal dispersal patterns between these habitats. It possesses a nationwide distribution across the United States.
