Abstract:

Rice Plant Hopper is one of the main pests in the rice production in Fujian Province and its occurrence is closely correlated to the meteorological conditions．Based on statistical methods, the relation between the occurrence levels of late rice plant hopper and meteorological factors in twenty-one counties was analyzed. The factors included temperature, humidity, precipitation and sunshine hours. The experiential statistical model for the meteorological grade was established based on the key meteorological factors. The validation results by the historical test showed that the forecast accuracy can be reached from 50% to 96% by comparing meteorological grade with actual grade in each region. The forecast effect was good and the model could be put into operational application.
