°C, 44% RH, night-time, 22°C, 65% RH) and the rainy season (daytime, 36°C, 46% RH, night-time, 25°C, 70% RH) in Thailand also showed no difference in the infected plants. These results indicated that low temperature or relative humidity did not affect the transmissibility of PBNV. The difference in disease incidences in the rainy and the dry seasons in Thailand could not be explained by the difference in climatic conditions but could possibly be accounted for by the difference in vector infestation.
