摘　　要：研究表明,北方特早熟棉区的辽宁省各地棉铃虫的发生程度与气温(年均等温线8～9℃)、降水(年平均降水量500～700mm)及寄主植物的分布三个条件重合程度呈明显的正相关。据此,将本省棉铃虫的发生区域划分为:重发生区、轻发生区、可发生区、偶发生区、不发生区,并绘制出棉铃虫区域划分图。Cotton bollworm (CBW) Helicoverpa armigera Hubner occurrence was studied in Liaoning province which was positively correlated with temperature,rainfall and host plants.Annual mean temperature 8～9℃,amount of precipitation 500～700mm,and fit host plants are favorable to CBW.According to the temperature,amount of precipitation and host plants,cotton bollworm occurrence zone was divided into five different regions,they are severely constant region,lightly constant region,possible region,occasional region and impossible region.Zone division figure was drawn in this paper.
