Since climatic conditions in Myanmar are favorable
for the spread of insect vectors, leafhoppers could be
suggested as being responsible for spreading phytoplasma
diseases. Further studies need to be undertaken in order to
define the relationship between phytoplasma transmissibility
and putative insect vectors. Mostly, China aster plants are
vegetatively propagated from cutting of young shoots rather
than direct sowing of seeds. Although disease incidence was
low, the use of infected propagating materials may become
the main source for spreading this phytoplasma. Based
on this result and previous studies, it could be concluded
that China aster plants are potential reservoirs for distinct
phytoplasmas.
