As a new prediction tool, the pest detector is widely used in monitoring and controlling agri-cultural and forest pests. The light trapping for forest pests in Hongtashan Nature Reserve of Yuxi was carried out by the pest detector in August 3, 2017. The results showed that with the advantages of trap-ping pest various in species, large in quantity and obvious in pest peak, the pest detector which was con-venient and relatively safe for natural enemies had better monitoring and controlling effect on Lepidoptera and Coleoptera pests. The dynamic occurrence and peak value of forest peats such as Scarabaeoidea, Ce-rambycidae, Sphingidae, Actias selene ningpoana of Saturniidae, Lasiocampidae, Geometridae and Arcti-idae were analyzed, which showed that the populations of the forest pests populations was not enough to threaten the region.%虫情测报仪是一种新型测报工具,广泛应用于农、林业虫害监测防控工作中. 2017 年3—8月,在云南省玉溪市红塔山自然保护区灵照山林区应用虫情测报仪开展森林害虫灯光诱测,结果表明,虫情测报仪诱集害虫种类多,虫量大,虫峰日期明显,对鳞翅目和鞘翅目森林害虫具有较好的监测和防治作用,且使用安全方便,对天敌相对安全,防治效果显著.根据诱测结果,对金龟子类和天牛类成虫以及天蛾科、蚕蛾科绿尾大蚕蛾、枯叶蛾、尺蛾类、灯蛾类等林业害虫的发生动态及峰值进行分析,结果表明,所监测到的森林害虫种群数量不大,对该区域森林不会造成威胁.
