摘　　要：为明确越冬代亚洲玉米螟发生动态,连续3年在辽宁沈阳开展了越冬代玉米螟化蛹及羽化进度调查和性诱监测。结果表明,越冬代玉米螟成虫羽化期为5月上旬至7月中旬,羽化高峰期在6月上、中旬。成虫性诱监测结果与化蛹及羽化进度调查结果基本一致,操作简便,可反映越冬代玉米螟发生动态,为预测预报及防治提供科学参考。不同田块性诱监测结果表明,越冬代玉米螟成虫的主要栖息场所是杂草地、小麦田和大豆田等植株生长茂密地块。To clarify the occurrence dynamics of the overwintering generation of Asian corn borer in Liaoning province,we conducted field sampling and sex pheromone monitoring in three consecutive years.The results showed the dynamics of emergence monitored by the sex trap were consistent with the field survey.The eclosion period of adult corn borer was from early May to mid-July and showed a peak in early to mid-June.According to the data of sex pheromone monitoring,it was identified that the main habits of the adult corn borer were lands with plants growing densely,such as weed,wheat,and soybean fields.With sex pheromone monitoring,the occurrence dynamic of the overwintering corn borer could be obtained more accurately and easily,which will provide a scientific reference for the prevention and control of the corn borer.
