| 随着高空灯在草地螟Loxostege sticticalis种群动态监测中的普遍应用, 分析高空灯的监测数据特点及其与传统黑光灯差异, 对基于高空灯监测数据进行种群动态趋势预测有着重要的意义。本研究通过提取并定义一系列的描述参数, 系统分析了河北省康保县2014年－2023年连续10年高空灯及黑光灯监测草地螟成虫的动态数据, 比较了高空灯与传统黑光灯对草地螟成虫监测的差异及相同点。结果表明, 高空灯监测下全年累计草地螟成虫诱集量是黑光灯的10倍以上;高空灯下雌蛾占比为0.53, 显著低于黑光灯;高空灯下始见期和终见期分别平均早于黑光灯3 d和2 d。在同一个蛾峰期内, 高空灯监测到的高峰日期比黑光灯平均早1 d。高空灯和黑光灯对草地螟监测的一致之处体现在:2种监测设备所示虫量的相对多少的年度变化趋势相同, 且整个监测期蛾峰次数均为3~4次, 蛾峰持续天数均为1~2 d。造成高空灯和黑光灯监测数据差异的主要原因是：两者分别对高空过境虫源和近地面虫源具有诱集优势。分析结果对于高空灯在草地螟种群预测预报上的应用提供了依据。 |

| With the increasing application of searchlight traps in monitoring the beet webworm (Loxostege sticticalis), evaluating their monitoring characteristics and comparing their effectiveness with traditional black-light traps is crucial for improving population forecasting accuracy. By extracting and defining a series of descriptive parameters, this study systematically analyzed ten years (2014-2023) of continuous monitoring data on adult L. sticticalis populations collected using both searchlight and black-light traps in Kangbao county, Hebei province. The differences and similarities in monitoring outcomes between the two trap types were examined. The results showed that searchlight traps captured over ten times more moths annually than black-light traps. The female moth proportion in searchlight traps was 0.53, significantly lower than in black-light traps. The initial and final appearance dates recorded by searchlight traps were, on average, three days and two days earlier, respectively. Within the same moth emergence peak period, the peak emergence date recorded by searchlight traps was, on average, one day earlier than that recorded by the black-light traps. Despite these differences, both searchlight and black-light traps showed consistent monitoring patterns. Annual population fluctuation trends were similar across both monitoring systems, and the number of moth emergence peaks per monitoring period remained consistent, typically occurring 3-4 times per season with each peak lasting 1-2 days. The observed differences in capture efficiency between searchlight and black-light traps were primarily attributed to their differing attraction mechanisms: searchlight traps are more effective at capturing high-altitude migratory moths, whereas black-light traps are more efficient at attracting moths closer to the ground. These findings provide a solid foundation for the application of searchlight traps in predicting and forecasting L. sticticalis population dynamics and improving pest early warning systems. |
