| Abstract: | The number of opitmum sampling to rat damage study from fields was conducted by Iwao method, and 6 kind of sampling methods were compared with statislical analysis. The results indicated that the Para- llel-Jumping method was better than the other five when damage esti mated to be 5%, defined exact was 0.25. The optimal sampling numbers were 5 nests in each sampling set, total about 200 nests from one field. |
