长白山自然保护区灯蛾科昆虫区系及多样性研究

On Fauna and Diversity of Arctiidae in Changbai Mountain Nature Reserve

2003—2004年对长白山自然保护区灯蛾科昆虫进行了系统调查,共采集到灯蛾科昆虫40种,隶属2亚科22属.长白山自然保护区灯蛾科昆虫以古北-东洋共有种为主,并包含少量的新北成分,优势种为四点苔蛾.灯蛾科昆虫物种多样性具有明显的垂直分布格局:阔叶红松林植被带多样性、丰富度均最高,随着海拔高度的升高,相应植被带内灯蛾科昆虫种类逐渐减少,个体数量上亦呈减少趋势;在时间分布上,全年以7月份的物种多样性最高,各月份由高到低的顺序依次是7月>6月>8月>5月>9月;长白山各植被带之间灯蛾科昆虫类群组成极不相似.

Systematic survey on fauna and species diversity of Arctiidae was carried out in Changbai Mountain Nature Reserve from 2003 to 2004,40 species of Arctiidae belonged to 2 subfamilies and 22 genera were caught. Among them,common species from Palaearctic and Oriental regions are main component,and a small amount of species belong to Nearctic component. Lithosia quadra was dominant species. Species diversity and richness of Arctiidae shows obviously vertical distribution pattern,among 4 vegetation zones,species diversity of Arctiidae is the highest in broad-leaved Korean pine forest zone. With altitude increasing,species diversities and individuals in corresponding vegetation zones decrease gradually. In view of temporal pattern of species diversity, species diversities show difference among the months,their order is as follows ：July 〉June〉August 〉May 〉September. Meanwhile,the similarity of Arctiidae among 4 vegetation zones is significant different.
