| 摘 要： | 棉铃虫在上世纪80~90年代,在我国多个老棉区严重发生或大暴发,致使棉花生产造成了严重损失。而后棉区迁移至新疆,加上抗虫棉的推广、综合治理措施的落实,有效遏制了棉铃虫的猖獗发生。近几年,在冀南多种作物上又有抬头,并有逐年加重的趋势,为对棉铃虫发生规律研究提出了新课题。

| Abstract: | Cotton bollworm occurred or broke out in many old cotton areas in 1980s-1990s, which resulted in serious losses of cotton production. After that, the cotton area moved to Xinjiang, with the promotion of insect resistant cotton and the implementation of comprehensive control measures, the rampant occurrence of cotton bollworm was effectively curbed In recent years, many kinds of crops in Southern Hebei have been growing up, and the trend is increasing year by year, which puts forward a new topic for the study of the occurrence of cotton bollworm. |
