摘　　要：为了更好地防治亚洲玉米螟,在哈尔滨地区通过春季剖秆进行越冬代亚洲玉米螟幼虫的发育进度调查,利用亚洲玉米螟性诱剂监测雄性成虫动态,研究田间亚洲玉米螟的发生规律。结果表明:2019-2021年哈尔滨地区亚洲玉米螟百秆越冬基数为8.6~9.5头,存活率为85.0%~89.1%,化蛹始见期为5月20日左右,化蛹盛期为5月26日至6月18日,化蛹高峰期为6月10日左右,羽化始见期为5月27日左右,田间亚洲玉米螟雄虫越冬代高峰期在6月17日-24日。综上明确了哈尔滨地区亚洲玉米螟发生规律,即越冬代亚洲玉米螟在5月中下旬开始化蛹,6月上旬到中旬达到化蛹高峰期,5月末开始羽化,6月中下旬田间出现雄性成虫高峰期,二代亚洲玉米螟雄性成虫田间发生时间主要集中在7月下旬至8月中旬。In order to control Ostrinia furnacalis better in the field, the occurrence regularity of O. furnacalis in the field was studied in Harbin. The development progress of the overwintering generation of larvae was investigated by dissecting the corn stalks in spring, and the dynamics of male adults were monitored by using sex pheromone. The results suggested that the over wintering base of O. furnacalis in Harbin district from 2019 to 2021 was 8.6-9.5 pre 100 stems, and the survival rate was 85.0%-89.1%. The initial pupation period was about May 20, the full incidence period of pupation was from May 26 to June 18, the peak pupation period was about June 10, and the initial eclosion period was about May 27. The peak period of overwintering generation of male O. furnacalis in the field was from June 17 to June 24. Based on the above results, the occurrence regularity of O. furnacalis in Harbin district was the overwintering generation of O. furnacalis began to pupate in the middle and late May, the peak of pupation in the early to middle of June, at the end of May began to eclosion, and the male adult moths appeared in the field in the middle and late June. The peak period of the second generation male adult moths in the field occurred in the late July to the middle of August.
