采用虫情测报灯诱集的方法，调查研究了2018 — 2020年甘肃省武威市凉州区玉米棉铃虫成虫发生动态及其与气候因子的相关性。结果表明，金武地区棉铃虫1 a发生2代和一个完整或不完整的第3代，2018 — 2020年平均月诱虫总量(y)与月气温总和(x)之间显著正相关，模型方程log10(y)=5.606 3×log10(x)-13.386，R2=0.796 2，F=15.6 > F0.05。

The population dynamics of adult cotton bollworm and its correlation with climate factors were systematically investigated in the Liangzhou District of Wuwei of Gansu Province from 2018 to 2020 by using the method of light trap. The results showed that there were two generations and a complete or incomplete third generation of cotton bollworm occurred every year in the Jinwu area. There was a significant positive correlation between the monthly trapping amount(y) and the monthly temperature amount(x) from 2018 to 2020. The model equation was log10(y)=5.606 3×log10(x)-13.386， R2=0.796 2， F=15.6 > F0.05 .
