Table 3 Adult emergence rates of larvae introduced into open ponds in the three experiments to evaluate transfer of PPF in semi-field cages
Ponds (distance betweeen pond and pond that served as bait station) | Mean proportion adult emergence (95% CI) | Odds ratio (95% CI) | p-value |
|---|---|---|---|
Control 1 - Mosquitoes released in semi-field cage & bait-station without PPF | |||
 closest to bait station (4.4 m) | 0.85 (0.82–0.87) | 1 |  |
 medium to bait-station (8.4 m) | 0.83 (0.80–0.86) | 0.87 (0.62–1.23) | 0.443 |
 furthest to bait-station (10.3 m) | 0.84 (0.81–0.87) | 0.99 (0.71–1.37) | 0.944 |
Control 2 - No mosquitoes released in semi-field cage & bait-station with PPF | |||
 closest to bait-station (4.4 m) | 0.89 (0.86–0.91) | 1 |  |
 medium to bait-station (8.4 m) | 0.89 (0.87–0.92) | 1.03 (0.72–1.49) | 0.854 |
 furthest to bait-station (10.3 m) | 0.88 (0.85–0.91) | 0.94 (0.65–1.34) | 0.721 |
Test - Mosquitoes released in semi-field cage & bait-station with PPF | |||
 closest to bait-station (4.4 m) | 0.25 (0.22–0.29) | 1 |  |
 medium to bait-station (8.4 m) | 0.58 (0.54–0.62) | 4.07 (3.19–5.21) | < 0.001 |
 furthest to bait-station (10.3 m) | 0.92 (0.89–0.94) | 33.89 (24.16–48.47) | < 0.001 |
Emergence inhibition due to auto-dissemination – comparison of test with control | |||
 control | 0.89 (0.84–0.94) | 1 |  |
 closest test pond (4.4 m) | 0.25 (0.20–0.33) | 0.042 (0.023–0.077) | < 0.001 |
 medium test (8.4 m) | 0.58 (0.51–0.66) | 0.173 (0.098–0.303) | < 0.001 |
