| 中文摘要: |
| 为了解北京小西山地区刺蛾科(Limacodidae) 昆虫发生动态,分析小西山地区生物多样性情况。在小西山地区设置5个虫情监测点,收集整理了2022 年全年监测数据。累计监测到刺蛾科昆虫216 只,隶属于9 属11 种,其中以梨娜刺蛾发生最多,其次为纵带球须刺蛾和桑褐刺蛾。对小西山地区刺蛾科昆虫进行发生动态分析发现,刺蛾科成虫发生期为6—9 月,集中在7 月。通过对不同监测点进行物种的Shannon-Wiener 多样性指数、Pielou 均匀度指数、Margalef 丰富度指数计算及
相关性分析,发现5 个监测点间物种多样性存在差异,其中西山国家森林公园范围内监测得到的刺蛾科昆虫物种数量和丰富度最高,但均匀度指数较低,一定程度上表明周边环境类型与昆虫多样性息息相关。自动虫情测报灯可在一定程度上监测昆虫多样性,控制林木害虫基数,同时还需结合其他多样化监测方法和手段,进一步完善区域内昆虫多样性数据,监测预报重大林木害虫的发生,保护小西山地区森林资源。 |

| In order to understand the diversity and occurrence dynamics of Limacodidae insects in the Xiaoxishan
area of Beijing, five insect monitoring points were set up in the Xiaoxishan area, and the monitoring
data in 2022 were collected and sorted out. A total of 216 Limacodidae insects were detected, belonging
to 11 species and 9 genera, among which Narosoideus flavidorsalis occurred the most, followed by
Scopelodes contracta and Setora postornata. The analysis of the occurrence dynamics of the Limacodidae
insects in the Xiaoxishan area found that the occurrence period of the Limacodidae adults was from June
to September, and concentrated in July. Through the calculation and correlation analysis of the Shannon-Wiener diversity index, Pielou evenness index, Margalef richness index in different monitoring points,
there were differences in species diversity among the 5 monitoring points. The number and richness of Limacodidae
insect species monitored in Xishan National Forest Park were the highest, but the evenness index
was low, indicating that the type of surrounding environment was closely related to the diversity of insects.
Automatic insect forecasting lights could monitor insect diversity to a certain extent and control the
base of forest pests. At the same time, it was necessary to combine other diversified monitoring methods
to further improve insect diversity data in the region, monitor and forecast the occurrence of major forest
pests, and protect forest resources in the Xiaoxishan area. |
