高校图书馆衣鱼孳生种类和生态调查

Investigation of Lepisma Breeding in Libraries of Universities

目的了解高校图书馆衣鱼的孳生情况。方法于2005年6月—2007年6月,选取安徽省38所高校图书馆的140间书库对衣鱼孳生情况进行调查。采用诱捕法和药激法收集衣鱼标本,同时动态观察衣鱼的季节消长和24h活动度等生态习性。结果调查高校图书馆38个,收集衣鱼标本3748只,隶属于衣鱼科(Lepismatidae),衣鱼属(Lepisma),包括敏栉衣鱼(Ctenolepisma villosa)、西洋衣鱼(Lepisma saccharina)、小灶衣鱼(Thermobia domestica)、台湾衣鱼(Lepisma serricom)。敏栉衣鱼为优势种。衣鱼活动第1个高峰在5月前后,10月后出现第2个高峰。衣鱼具有昼伏夜出性,20:00开始活动,24:00是活动高峰,随后活动度明显下降,到翌日5:00停止活动。结论安徽省高校图书馆衣鱼孳生情况较严重,图书馆害虫的防制需引起重视。

Objective To investigate the species and ecosystem of lepisma breeding in libraries of universities. Methods The lepisma samples were collected from the libraries of universities in Anhui by trapping bottle and chemical stimulating and the life cycle and the biocycle were observed meanwhile, from June 2005 to June 2007 .Results 38 libraries were examined and 3 748 lepismas were gathered, belonging to 1 family 1 genus and 4 species. The first activity peak appeared in May, and the second in October. Lepismas were active from 20： 00 to 5 ： 00.The activity peak appeared at 24： 00.This was identical with the living habits of their hiding by day and coming out at night. Conclusion The lepisma pollution in libraries of universities is serious in Anhui province and the Ctenolepisma villosa is the dominant species.
