| Abstract: |
| In order to reduce the ecological risk of rodenticide caused by chemical control，and aiming at
the occurrence dynamics and habitat characteristics of agricultural rodents in Guangdong Province，the emerging
TBS at home and abroad was optimized，and the rodent control test was carried out in Xinhui District of Jiangmen
City，Guangdong province. The results showed that the number of effective burrow per hundred metres in the
drainage channel，two sides of the ploughing road and the high ridge was 36.2±6.77，37.4±6.39 and 17.3±
4.13 respectively. These places were the main habitats of the farmland rodents and the place position of TBS.
After changing the entrance of the fence into square with 10 cm×12 cm，and adding rat blocking tablet on the top
of the fence and the surrounding of the fence hole，the average number of rats trapped in the TBS fence was 10.00±
1.12 each month，and the total biomass was 7 898.0 g in eight months，which was obviously higher than that of the
conventional TBS test area. After applying optimized TBS technology，the rodent density decreased by 75.11%，and
the rodent damage rate of rice was 1.23%. The control effect was slightly lower than that of chemical control，but it
had significant ecological significance. |
