摘　　要：本文测定了吉林省公主岭市玉米地中20 m×20 m矩形TBS(R-TBS)及长60 m和30 m的线形TBS(L-TBS)的控鼠效果、保护辐射半径及其防控害鼠的经济效益。在此基础上评估了玉米产量与L-TBS捕获量之间的关系。结果发现,当地优势害鼠最大活动距离(TBS保护辐射半径)超过100 m;R-TBS、L-TBS(60m)、L-TBS(30 m)的鼠害控制效果分别为84.57%、77.26%、66.77%,在保护辐射范围内(r=100 m)单位面积玉米产量与对照区产量差异不显著。但可挽回损失755、744、713 kg/hm2。通过计算其投入产出关系,建议东北地区玉米地每3 hm2使用一个60 m长的LTBS进行害鼠防控。In this study, we assessed the effects, protection halo and economic benefit of 20mx20m R-TBS, 60m L-TBS and 30m L-TBS on rodent management in maize fields in Gongzhuling county of Jilin Province. We also analyzed correlation between trapped rodent numbers by L-TBS and corn yields. It was found that activity distance of dominant rodent species （protection halo of TBS） were more than 100m; rodents population size decreased by 84.57%, 77.26% and 66.77% respectively, when using 20×20m R-TBS, 60m L-TBS and 30m L-TBS for rodents management in maize fields. There was no significant difference between corn yields in the treatment （r=100m） and the control area, while avoid yield loss at 755, 744, 713 kg/hm2. Corn yields increased with amplifying of rodent numbers captured by L-TBS. Based on analysis on economic benefits, 60m L-TBS was a good choice for managing rodents in this farming system.
