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 understand the breeding of the fish in the university library. Methods From June 2005 to June 2007, 140 bookstores of 38 university libraries in Anhui Province were selected to investigate the breeding status of the fish. Trapping method and drug-induced method were used to collect the specimens of the fish, and the ecological habits such as the seasonal fluctuation and 24h activity of the fish were observed dynamically. Results A total of 38 university library specimens were collected and 3,748 specimens were collected. They were subdivided into Lepismatidae, Lepisma, including Ctenolepisma villosa, Lepisma saccharina, Thermobia domestica, Lepisma serricom. Sensitive pike fish for the dominant species. The first peak of the fish-feeding activity was around May and the second peak appeared after October. Diving fish have nocturnal nocturnal emission, starting activities at 20:00, 24:00 is the peak activity, then significantly decreased activity, to 5:00 the next day to stop activities. Conclusions The library of breeding fish in university libraries in Anhui Province is more serious. The prevention and control of library pests needs attention.
