为了解亚洲玉米螟越冬代种群与温度的相关关系，指导玉米螟预测预报和田间防治策略，本研究对2006-2023年河南省漯河市自动虫情测报灯和当地温度的历史数据进行分析。结果表明，18年来河南漯河地区1-6月有效温度累积值显著升高100.32 ℃，超过发育起点温度天数显著增加9.37 d；玉米螟越冬代发生关键时间始见日、高峰日和终见日分别显著提前了14.91、10.08和11.17 d。线性回归发现，有效温度累积值与越冬代的发生关键时间呈显著负相关，有效温度累积值每上升10 ℃，始见日、高峰日和终见日分别提前1.35、0.81和0.53 d。

To clarify the relationship between overwintering generation of Asian corn borer(ACB), Ostrinia furnacalis(Guenée)and the temperature, and to provide a reference for prediction and control strategies of this pest, an investigation on historical data under monitoring light and local temperature, was carried out in 2006-2023, in Luohe City, Henan Province. The results showed that effective accumulated temperature and the days above developmental threshold temperature had significantly increased 100.32 ℃ and 9.37 d from January to June among an 18-year period, respectively. Additionally, the first occurrence day, peak occurrence day, and last occurrence day(key occurrence dates) of the overwintering generation of ACB had significantly advanced by 14.91, 10.08, and 11.17 days, respectively. Linear regression analysis revealed a significant negative correlation between the effective accumulated temperature and the corresponding key occurrence dates of the overwintering generation. For every 10 ℃ increase in the effective accumulated temperature, the first occurrence day, peak occurrence day, and last occurrence day advanced by 1.35, 0.81, and 0.53 days, respectively.
