目的 对浙江省天目山、九龙山、清凉峰3个国家级自然保护区蠓科昆虫种类进行调查,并进行保护区间的蠓虫相似性分析。方法 采用网扫法、马氏网采集法和灯诱法进行昆虫采集,应用Jaccard二元相似性系数(SI)对各保护区蠓类相似性进行聚类分析。结果 浙江省3个保护区共发现蠓科昆虫3亚科9属56种,其中浙江省新纪录52种;相似性分析结果表明天目山与清凉峰SI最高(0.24),九龙山与天目山SI较低(0.21),九龙山与清凉峰SI最低(0.20)。结论 为浙江省蠓科昆虫的种类分布、蠓害防治和蠓传疾病研究提供了基础数据;保护区蠓类SI的高低主要与地理位置 、气候条件、人为干扰活动等因素相关。

Objective To determine the species diversity and similarity analysis of Ceratopogonidae in Tianmushan, Jiulongshan, Qingliangfeng National Nature Reserve of Zhejiang province. Methods The insect net capture, Malaise capture and light trap were used to capture biting midges. The similarity analysis of biting midges was clustered by the Jaccard bivariate similar coefficient. Results In the three National Nature Reserve, 56 species of 9 genera belonging to 3 subfamilies of Ceratopogonidae were found, including 52 new record species. The similarity analysis indicates that the similarity coefficient between Tianmushan and Qingliangfeng Reserve is the highest (SI=0.24); between Jiulongshan and Tianmushan Reserve is the lower (SI=0.21); between Jiulongshan and Qingliangfeng Reserve is the lowest (SI=0.20). Conclusion This study provides reference data for species diversity of Ceratopogonidae, control of bloodsucking midge and midge-borne viral diseases. The clustering analysis indicates that the similarity coefficient is mainly related to the factors of geographic locations, weather conditions, and human activities.
