Abstract: Objective To investigate rodent population distribution and rodent control effectiveness in a working area of Japanese abandoned chemical weapons in eastern Jilin province, China. Methods The trapping method was used to capture rodents from June to August of 2016 in 3 habitats (mixed coniferous-broadleaf forests, marginal areas of cultivated land, and temporary settlements). The chi-square test was used to compare the capture rate of rodents in different habitats. Rodent control was conducted with poison baits in 4 zones of the working area and the control effectiveness was determined in July 2017. Results A total of 398 rodents were captured, involving 10 species from 8 genera. The dominant species were Apodemus agrarius (37.19%) and Tscherskia triton (32.66%), followed by Rattus norvegicus (9.30%) and A. peninsulae(8.54%). After 10 days of deratization, deratization rates in the 4 zones were 71.43%, 84.85%, 81.25%, and 91.30%, respectively, averaging 84.79%.The difference of mousetrap rate between different habitats and month was statistically significant (χ2=119.431, P<0.001; χ2=15.872, P<0.001). Conclusion There were many kinds of rodents in this area, the density of rodents was high, and the effect of poison bait is remarkable.

摘要: 目的 调查吉林省东部某日本遗弃化学武器作业区的鼠形动物种群分布,观察灭鼠效果。方法 2016年6-8月在作业区内选择针阔混交林、耕地边缘、临时住区3种生境,采取鼠夹法调查鼠形动物,以χ2检验比较不同生境的捕获率;2017年7月在作业区内的4个区域开展毒饵灭鼠,计算灭鼠率,观察灭鼠效果。结果 共捕获鼠形动物398只,经鉴定为8属10种,其中黑线姬鼠和大仓鼠为优势种群,分别占37.19%和32.66%,其次是褐家鼠和朝鲜姬鼠,分别占9.30%和8.54%。毒饵灭鼠10 d后,4个区域灭鼠率依次为71.43%、84.85%、81.25%和91.30%,平均灭鼠率为84.79%。不同生境和月份捕鼠率差异有统计学意义(χ2=119.431,P<0.001;χ2=15.872,P<0.001)。结论 该作业区鼠形动物多样,密度较高,毒饵灭鼠效果显著。
