Data of a pest control business was used to study infestation with the brown, or Norway rat (Rattus norvegicus Berkenhout, 1769]) in the City of Magdeburg for the year 1999. Swarms of rats were found to live all over the territory of the city. Blocks of residential buildings erected during G. D. R. times and, more specifically, their basements were noted to be focal sites of infestation with rats. The problem of rats living in the sewerage system of the city turned out to be unresolved. Detailed reference is made to rodenticides and active substances as well as to control strategies. The priority given to economical issues over the application of scientific findings is considered to be the decisive factor which accounts for the needs in the extermination of rats. 相似文献
