| 中文摘要: |
| 近年来,棉铃虫在吉林省各地区玉米田为害,成为了潜在的玉米穗部重要害虫。明确棉铃虫在吉林省的种群动态、虫源性质,对其早期预警与综合防控具有重要意义。本研究在吉林省中西部的公主岭市,综合运用常规监测、卵巢解剖、田间调查、气象分析、轨迹分析等技术和方法,对棉铃虫的发生时间、发生世代、虫源地、迁飞情况进行了初步研究。结果表明,8月上旬－10月上旬为棉铃虫成虫发生期,其中8月中旬－9月下旬是发生高峰期。棉铃虫成虫在当地发生2代(第3代和第4代),第3代为迁入世代,第3代高峰期的虫源主要来自于辽宁省部分地区。第4代主体为本地繁殖世代,其为害期正值当地玉米灌浆至蜡熟期。第4代棉铃虫成虫羽化后滞留本地的种群因气候以及食物原因而消亡。迁出期的风向不利于棉铃虫种群回迁。 |

| Helicoverpa armigera (Hübner) is becoming a pest of maize ear and causes serious damage to maize in Jilin province in recent years.Understanding the occurrence dynamics and migration pathways is important to monitor and control the pest. In this study, the occurrence period, generation, source areas and migration of the moth were investigated by monitoring, field survey, ovarian development observation, weather analysis and track analysis. The results showed that the moth occurred from early August to early October, with a peak from middle August to late September. Population characteristics indicated that there were two generations, the third and the fourth generations, occurred in Gongzhuling city per year. The third generation was immigrants and the moths at peak period came from part of Liaoning province. The major of the fourth generation was emerged locally, which caused serious damage to maize ear. The fourth generations of moth remaining in local would be extinct due to disadvantageous climate and food. The wind direction is unfavorable to the southward migration population. |
