(1) While the rate of RSV diseased plants in the current pentad is
highly dependent on the amount of viruliferous L. striatellus
two pentads prior, which is the biological parameter, it is also
closely associated with the three important meteorological
parameters in the aerial layer, which are wind speed, relative
humidity, and insolation duration. On the one hand, in biology,
the occurrence and prevalence of rice stripe disease are directly
caused by RSV transmitted by L. striatellus, and thus, the amount
and viruliferous rate of L. striatellus during the early paddy stage
are the vital biological factors to rice stripe disease. On the other
hand, the occurrence and prevalence are also closely associated
with temporal and spatial distributions of meteorological
elements in the aerial layer. The wind, humidity, and light affect
not only RSV growth and propagation but also growth and
development of the host plant rice. Specifically, high wind
speed ensures enough ventilation and causes dryness in the
field; hence, RSV cannot cause pathogenicity. However, high
relative humidity is beneficial for the occurrence and spreading
of RSV. Further, long insolation duration causes evaporation
and drying and is not conducive to the breeding and spreading
of the RSV.
