摘要
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。
Occurrence degree of cotton bollworm, Helicoverpa armygera and meteorological data from 1982 to 1997 are analyzed in this paper. The results show that the weather is the key factor affecting the insect occurrence degree. It is beneficial to the bollworm incidence under following condition: less rainfall and higher temperature during the pupal stage, and moderate or more and scatterd rainfall during larval stage of the pest. These results provide basis for the forecasting of Helicoverpa armigera.
