摘　　要：目的调查安徽省芜湖市图书馆内蜚蠊种群构成及季节消长状况,为蜚蠊的有效防制提供科学依据。方法采用盒式诱捕法于2008年1-12月对图书馆内蜚蠊孳生情况进行调查。结果共捕获蜚蠊1080只,分类鉴定为2科2属4种,即美洲大蠊、黑胸大蠊、澳洲大蠊和德国小蠊,其中德国小蠊占捕获总数的51.85%,为优势种;图书馆蜚蠊全年平均侵害率为53.32%,平均密度为2.56只/间,其中学生自修室侵害最为严重;蜚蠊的繁殖高峰期在8月,且其密度消长与气温高低密切相关(r=0.954,P<0.01)。结论芜湖市图书馆蜚蠊侵害状况较为普遍,蜚蠊防制工作十分紧迫。Objective To investigate the population composition and seasonal variation of cockroaches in libraries of Wuhu city,Anhui province for the development of effective control strategies. Methods The pests in libraries were studied using capture boxes from January to December 2008. Results A total of 1080 cockroaches,4 species in 2 genera,2 families,were captured,namely Periplaneta americana,P. fuliginosa,P. australariae,and Blattella germanica. Among them,B. germanica was the predominant species,accounting for 51.85%. The average year-round infestation rate was 53.32%,with an average density of 2.56 pests per room. The reading rooms were the worst affected. The reading rooms were most badly affected. The peak breeding season was in August,and the density variation was highly temperature-dependent（r=0.954,P〈0.01） . Conclusion Libraries in Wuhu city were highly roach-infested demanding immediate and effective control measures.
