Three Japanese strains of mycoplasmalike organism (MLO) transmitted by Macrosteles orientalls, potato purple-top wilt MLO (PPWM) in Japan and aster yellows MLO (AYM) from USA were compared with each other from the viewpoints of their host range and mode of transmission by vectors. The three Japanese MLO strains and AYM were successfully transmitted by M. orientalis and M. fascifrons to test plants, but PPWM was not transmitted by these vectors. Scleroractus flavopictus transmitted PPWM but did not others. The host ranges of the three Japanese strains and AYM very resembled showing minor differences from each other. When M. orientails was fed on Cryptotaenia japonica infected with the three Japanese strains and AYM, respectively, percentages of infectious individuals increased in proportion to acquisition feeding period to reach about 80% by 5 to 7 days. In the case of M. fascifrons, however, only 30-40% of the individuals became infectious. The three Japanese MLO strains and AYM had incubation periods of 14-23 days (18-19 days in average) and were transmitted by M. orientalis in persistent manner. From these results, it became clear that the three strains of M. oreintalis-transmitted MLO in Japan were related to AYM from USA but not to PPWM in Japan.
