城区特殊行业鼠类侵害现状调查

Investigation on the Situation of Encroachmet by Mouse in Special Areas in the City Zone

目的 :摸清城区特殊行业鼠类侵害现状及发生鼠害的原因 ,为有的放矢的降低鼠密度提供科学依据。方法 :将城区饭店、副食店、综合商店及五金百货商店作为 4类行业 ,用夹日法调查鼠密度及鼠种。结果 :4类特殊行业平均鼠密度为 1.83 % ,其中综合商店密度最高 ,为 2 .83 % ,其次是饭店为 2 .0 1% ,五金百货商店及副食品店较低 ,分别为1.5 1%及 1.3 1%。共捕鼠 13 6只 ,其中褐家鼠 10 6只 ,小家鼠 2 4只 ,黑线仓鼠 2只 ,北小麝 4只 ,褐家鼠为优势种 ,占捕鼠总数的 77.94%。结论 :城区饭店、副食店、综合商店及五金百货店等特殊行业鼠类侵害较重 ,其主要原因是这些单位环境阻力小 ,鼠容量高 ;

Objective: To investigate the encroachment situation and the cause happened by mouse, to provide basis for reducing the mouse density. Methods: An investingation was carried out on rat density and species with the method of night trapping in special areas including restaurants,no staple food shops, multiple shops, the five metal shops in the city zone of Weifang city,Shandong province. Results: The rat density was 2.83 %, 2.01 %, 1.51 %, 1.31 % respectively in the four areas, the average density was 1.83%. 136 mice were captured, Rattus norvegicus,Mus musculus, Circetulus barabensis,Suncus murinus were 106,24,2,4 respectively, Rattus norvegicus was predominant rat species ( 77.94 %). Conclusions: Encroachment by mouse was seriously in these special areas, it's cause was high rat density, perishing rats was not carried out centralizedly.
