Table 6. Ranking of termite resistance based on the two-choice test
| Wood type | Ranking |
| Pairing 1 | Pairing 2 | Pairing 3 | Sum |
| Abies holophylla | v. | Pd | 1.0 | v. | Pk | 1.0 | v. | Zs | 1.0 | 3.0 |
| Pinus densiflora | v. | Pk | 1.5 | v. | Ah | 2.0 | v. | Zs | 1.0 | 4.5 |
| Pinus koraiensis | v. | Pd | 1.5 | v. | Ah | 2.0 | v. | Zs | 1.0 | 4.5 |
| Zelkova serrata | v. | Pd | 2.0 | v. | Pk | 2.0 | v. | Ah | 2.0 | 6.0 |
Numbers listed in the same row indicate the feeding preferences of termites for each of the four wood species, i.e., 1.0 (preferred), 1.5 (similar), or 2.0 (not preferred), in comparison with the other three wood species. The sum was obtained by adding the values in each row, and a higher sum value indicates a higher ranking for termite resistance.
Pd: Pinus densiflora, Pk: Pinus koraiensis, Zs: Zelkova serrata, Ah: Abies holophylla.
