摘　　要：在不同定温下观察了棉铃虫各发育阶段的发育速度，测得其发育始点和有效积温常数。运用测得的这些常数，推测棉铃虫在山东省主要棉区一年发生的代数和发生时期，与实测情况基本相符，在预测其发生期和地理分布时可供参考。In the laboratory under various constant temperature conditions,the development speeds of every development stage of the cotton bollworm,Heliothis armtgera Hubner,were observed.Besed on these results,their starting point of development and constants of effective accumulative temperature were computed respectively.It is possibl to estlmte the number of generations and the emergence period of cotton bollworm in Shandong with these biological constants.Their biological constants are also used to forecast the emergence period and geographical distribution of cotton bollworm.
