| 中文摘要: |
| 为了解漯河地区地老虎类成虫的种群动态, 2006年－2021年, 在河南省漯河利用虫情测报灯对其成虫种群进行了持续监测。结果表明, 16年诱集的地老虎类害虫共计4种44 899头, 主要包括小地老虎Agrotis ipsilon (Hüfnagel)、大地老虎A. tokionis Butler、黄地老虎A. segetum (Denis et Schiffermüller)和八字地老虎Xestia c-nigrum (Linnaeus), 不同种类间年诱虫量差异较大。混合种群发生盛期在5月下旬至8月上旬。小地老虎在河南漯河1年可见4代成虫, 以第1代诱虫量最大; 诱虫高峰主要集中在5月下旬至7月上旬(1代)和7月上旬至8月上旬(2代); 近16年间小地老虎在各年均为优势种, 但其虫量和诱虫的比例在近几年呈明显下降的趋势。黄地老虎年度诱虫量在近几年上升趋势明显, 诱虫高峰主要集中在6月中旬至7月上旬。大地老虎成虫盛发期在10月上旬至10月下旬, 八字地老虎所占比例有所上升, 但全年无明显的诱虫高峰; 而且这两个种类的诱虫数量较少。 |

| To understand the population dynamics of cutworms, we consecutively monitored the adult population of these pests in Luohe with a light trap from 2006 to 2021. The results showed that 44 899 individuals of four species were trapped in the past 16 years, including Agrotis ipsilon (Hüfnagel), A. tokionis Butler, A. segetum (Denis et Schiffermüller) and Xestia c-nigrum (Linnaeus). There was a great difference in the number of annual catches among different species. The emergence peak of the mixed population was in late May to early August. The adults of A. ipsilon occurred four generations per year, and the first generation held the most catches. The emergence peak of A. ipsilon was mainly in late May to early July (the first generation) and early July to early August (the second generation). Over the 16 years, A. ipsilon was the dominant species in each year, but its number and proportion showed a significant decline in recent years. In recent years, the annual catches of A. segetum increased obviously, and the population peaked mainly in mid June to early July. A. tokionis and X. c-nigrum had relatively small numbers. The emergence peak of A. tokionis was from early October to late October. The adult population of X. c-nigrum increased in recent years, but there was no clear peak throughout the year. |
