Table 1 Theoretical population trend with nine sterile males released for each initial fertile wild male per generation with a 5-fold rate of increase (after Knipling [1])
From: Historical applications of induced sterilisation in field populations of mosquitoes
Generation | Density of fertile males | No. released males/generation | Ratio of sterile to fertile males | Population density |
|---|---|---|---|---|
1 | 1,000,000 | 9,000,000 | 9:1 | 500,000 |
2 | 500,000 | 9,000,000 | 18:1 | 131,580 |
3 | 131,580 | 9,000,000 | 68:1 | 9,535 |
4 | 9,535 | 9,000,000 | 944:1 | 50 |
5 | 50 | 9,000,000 | 180,000:1 | 0 |
