Abstract: Objective To verify the efficacy of trap?barrier system (TBS) in controlling rodents in Tianjin, China. Methods Four TBS plots and three control plots were set in the corn field for study on rodent control. Results There were three species of pestiferous rodents in the corn field in Tianjin, i.e., Tscherskia triton, Rattus norvegicus, and Apodemus agrarius (in small numbers). The capturing effect of TBS was 2.1 times better than that of night trapping method. With TBS for rodent control, the production of corn field increased by 21.7 kg/667 m2, resulting in an increase of 10 839.15 kg in the 33.3 hm2 field, which amounts to 14 090.90 yuan; the investment?benefit ratio was 1∶3.88. Conclusion TBS holds promise for promotional application in Tianjin and elsewhere, China.

摘要： 目的 验证围栏捕鼠(TBS)技术在天津地区对鼠害的控制效果。方法 在玉米田建立4个TBS区和3个对照区进行害鼠控制研究。结果 天津地区玉米田的主要害鼠种类有大仓鼠、褐家鼠和少量的黑线姬鼠;TBS技术捕鼠效果是普通夹夜法的2.1倍;TBS技术在投入玉米田防鼠后每667 m2可增产21.7 kg, 33.3 hm2共增产10 839.15 kg, 折合经济收入为14 090.90元, 投入效益比为1∶3.88。结论 研究表明TBS技术在天津地区有一定的推广价值。
