Cryptotaenia japonica witches' broom phytoplasma (CJWP) and onion yellows phytoplasma (OYP) were transmitted by the leafhopper H. sellatiformis. CJWP and OYP were also detected by PCR in H. sellatiformis fed on infected plants. Latent periods in H. sellatiformis of CJWP and OYP were 13-17 days. The phytoplasmas were detected by PCR in leafhoppers at about 7 days after the start of acquisition feeding. This is the first report of the transmission of CJWP and OYP by H. sellatiformis.
