Euscelidius variegatus
leafhopper
Euscelidius variegatus is a multivoltine, polyphagous leafhopper in the family Cicadellidae, widespread across Europe and North America. It serves as a natural vector of 'Candidatus Phytoplasma asteris' (chrysanthemum yellows strain) and as a laboratory vector for Flavescence dorée phytoplasma and the X-disease phytoplasma affecting cherry production. The species has become a model organism for studying phytoplasma-vector interactions due to its ease of laboratory rearing compared to natural vectors like Scaphoideus titanus. Development from egg to adult occurs in approximately 35 days under controlled conditions, with adult longevity averaging 52 days.
