摘　　要：美国白蛾[Hyphantria cunea (Drury)]是重要的林业害虫,对吉林省中西部农林业生产造成威胁。目前尚无美国白蛾在此区域种群动态的系统研究。2017-2019年,选用虫情测报灯、高空探照灯对美国白蛾的成虫动态进行监测,并评价其应用效果。结果表明:两灯在监测美国白蛾消长动态上一致,6月上中旬是成虫始见期,终见期为9月中旬。发生趋势曲线显示两个高峰期,6月下旬—7月上旬是1代成虫高峰期,8月是2代成虫高峰期。虫情测报灯、高空探照灯逐日诱蛾量具相关性。但两灯在诱集数量上未见一致性,对不同世代成虫的诱集效果也未体现规律性,这可能与此区域美国白蛾的虫源组成有关。本研究结果可为制定美国白蛾的防治策略提供科学依据。Hyphantria cunea(Drury)is an important forestry pest.It is becoming a potential threat for agri-culture and forestry in mid-west Jilin Province and there is no studies on its population dynamics in this area.Occurrence regularity and trapping effects were investigated based on pest forecast light trap and high-altitude search light during 2017-2019.The results showed:The moth's population dynamics was similar between the two kind of light traps;the moth occurred from early-middle June to middle Septem-ber,with two peaks from late June to early July(first generation adult)and August(second generation adult).There was relationship in daily captured numbers by the two kind of light traps.No consistency was found in total number,and no regularity was found in different generation numbers,which probably was caused by the composition of the moths source.These findings provide a scientific basis of effective control for the pest in the region.
