摘　　要：研究山西农业大学林业生态站人工沙棘林螟蛾科的物种组成及发生规律,旨在为晋西北沙棘灌木林螟蛾科害虫的发生、防治和健康经营提供科学参考。2014年5—10月,每日夜间以灯诱法对林业生态站人工沙棘林内的螟蛾科昆虫进行监测,制作标本,物种鉴定后,统计物种组成和多度分布,计算多样性指数、丰富度指数、均匀度指数、优势度指数,并分析群落相似性。结果表明,山西农业大学林业生态站人工沙棘林内共有螟蛾科19个属的20个物种,其中,库氏歧角螟是优势种,7月物种的个体数达到最多,为259头,7、8月的螟蛾科物种数均为15种;多样性指数和丰富度指数均为8月最高,分别为2.3228和2.9451;均匀度指数5月最高,为0.9945;优势度指数7月最高,为0.7237;6、7月的群落相似性最高,为0.7500。该地区的螟蛾科害虫治理主要是防治库氏歧角螟,应该集中在7月进行。This paper mainly studied the species composition and occurence regularity of Pyralidae in artificial seabuckthorn plantation of forestry ecological station in Shanxi Agricultural University to provide reference materials for occurrence,control and healthy management of the pest of the Pyralidae in the seabuckthorn shrubbery forest in northwest Shanxi province.From May to October 2014,light trapping and monitoring of Pyralid moths in artificial seabuckthorn plantation was carried out.The species composition,abundance distribution,diversity index,richness index,evenness index,dominance index and community similarity analysis of the Pyralidae were calculated.The results showed that there were 20 species in 19 genera of Pyralidae in the artificial seabuckthorn plantation of forestry ecological station in Shanxi Agricultural University.Among them,the Endotricha kuznetzovi was a local dominant species,and the number of species reached the largest number of individuals in July,which was 259 heads.There were 15 species of Pyralidae in July and August.The diversity index(2.3228)and richness index(2.9451)were the highest in August.The evenness index was the highest at 0.9945 in May,and the dominance index was the highest at 0.7237 in July.The community similarity between June and July was the highest,which was 0.7500.The results showed that main pest of Pyralidae was Endotricha kuznetzovi in July.
