1989～1993年,采用夜夹法对有代表性的城镇和农村居民点进行鼠密度监测。结果平均鼠密度为7.03％(578/8223),农村鼠密度明显高于城镇,近3年尤为显著(x~2=77.5,P<0.01);室外鼠密度前2年显著高于室内(x~2=23.53,P<0.01),后3年无显著性差异。鼠密度的季节高峰在秋季,室内为冬季,黑线姬鼠在春季还有一个高峰。经鉴定578只鼠,分属6个品种,黑线姬鼠是室外的主要优势鼠种,褐家鼠和小家鼠是室内的主要鼠种。提示今后该县灭鼠应采取经常与突击相结合和室内外并重的措施,并把初秋作为灭鼠的重点时期。
From 1989 to 1993, the night clip method was used to monitor the density of the representative urban and rural settlements. Results The average density of rats was 7.03% (578/8223). The density of rats in rural areas was significantly higher than that of urban areas, especially in the past three years (x ~ 2 = 77.5, P <0.01) ~ 2 = 23.53, P <0.01), no significant difference after 3 years. Rodent season peak season in the fall, the indoor winter, black Apodemus in spring there is a peak. 578 rats were identified, belonging to 6 varieties, Apodemus agrari is the main outdoor rat species, Rattus norvegicus and Mus musculus are the major indoor rat species. Prompted that the future rodent control in the county should take frequent and surprise combination of both indoor and outdoor measures, and early autumn as a key period of anti-rat.
