摘要
[目的]探明四川雪宝顶国家级自然保护区蛾类昆虫种类与分布,掌握该保护区蛾类昆虫资源现状。[方法]采用灯诱法采集蛾类昆虫,并对标本进行分类学鉴定及多样性分析。[结果]经初步鉴定,该保护区内蛾类昆虫共19科160种2418头,其中尺蛾科个体数量(524头)和种数最多(45种)。3个保护站中,虎牙保护站蛾类群落个体数量最多(1116头),多样性指数(2.257)、均匀度指数(0.8333)最大,优势度指数最小(0.1317),个体分布最均匀,结构最为稳定。在4种植被类型中,针阔混交林中的蛾类多样性指数(2.345)、均匀度指数(0.8619)与丰富度指数(2.485)均最大,优势度指数最小(0.1201),个体分布最为均匀,群落结构最为稳定。[结论]尺蛾是雪宝顶国家自然保护区的优势种类,虎牙保护站和针阔混交林的蛾类结构最为稳定。
[Objective]To investigate the species and distribution of moth insects in Xuebaoding National Nature Reserve in Sichuan Province and understand the current status of moth insect resources in the reserve.[Method]The moth insects were collected by using light induction method,the taxonomic identification and diversity analysis were conducted on the collected specimen.[Result]According to the preliminary identification,a total of 2418 moths belonging to 160 species oF_(1)9 families were found in the reserve,among which the number of individual moths(524)and the number of species(45)were the most.Among the three conservation stations,Huya Station had the largest number(1116)of moth communities,and the largest diversity index(2.257)and evenness index(0.8333),and the smallest dominance index(0.1317).The moths of Huya Station had the most uniform distribution and the most stable structure.Among the four vegetation types,the diversity index(2.345),evenness index(0.8619)and richness index(2.485)of moths in coniferous and broad-leaved mixed forest were the largest,while the dominance index(0.1201)was the smallest,and the distribution of moths was the most uniform,and the community structure was the most stable.[Conclusion]Geometridae was the dominant species in Xuebaoding National Nature Reserve.The structure of moths was the most stable in Huya Station and coniferous and broad-leaved mixed forest.
