Table 6. Bed bug population estimation based on m-r-r technique.
| Apt. # | Trapping period | Total # of marked adult bed bugs existed at 4 d 1 | Proportion of marked adult bed bugs 2 | Estimated total adults | Proportion of adults in unmarked bed bugs | Estimated total population | Standard deviation |
|---|---|---|---|---|---|---|---|
| 1 | 4 to 7 d | 505 | 0.3778 | 1,337 | 0.09354 | 14,291 | 1,578 |
| 2 | 4 to 6 d | 226 | 0.7059 | 320 | 0.13158 | 2,433 | 381 |
| 5 | 4 to 7 d | 177 | 0.1396 | 1,268 | 0.10304 | 12,305 | 1,630 |
| 6 | 4 to 7 d | 173 | 0.5476 | 316 | 0.02794 | 11,306 | 1,586 |
1 This is the number of bed bugs initially released minus the recaptured marked bed bugs during the first three days.
2 This is the (R+1)/(C+1) used in the formula for population estimation.
