Colladonus
Colladonus is a genus of leafhoppers in the family Cicadellidae, established by Ball in 1936. Species in this genus are native to North America and are economically significant as vectors of X-disease phytoplasma (Candidatus Phytoplasma pruni), which affects stone fruit crops including cherries, peaches, and nectarines. The genus includes notable species such as Colladonus clitellarius (saddled leafhopper) and C. montanus, both documented as important disease vectors.
