通过对１９８２～１９９７年棉铃虫发生动态与气象资料分析认为，影响该虫发生的关键因子是气候。棉铃虫蛹期雨量偏少、气温偏高，幼虫期雨量适中或偏多、雨日分散有利于棉铃虫的发生。这为棉铃虫预测预报提供了依据。
According to the dynamic and meteorological data analysis of cotton bollworm from 1982 to 1997, it is considered that the key factor affecting the occurrence of the insect is climate. The bollworm number of cotton bollworm was less than that of the normal one, and the temperature was too high. The amount of rain in the larvae was moderate or excessive, and the rainy day was conducive to the occurrence of cotton bollworm. This provided the basis for forecasting cotton bollworm.
