Table 3 Adult emergence rates of larvae introduced into open ponds in the three experiments to evaluate transfer of PPF in semi-field cages

From: Testing a pyriproxyfen auto-dissemination station attractive to gravid Anopheles gambiae sensu stricto for the development of a novel attract-release -and-kill strategy for malaria vector control

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
 furthest test (10.3 m) 0.92 (0.85–0.98) 1.437 (0.846–2.444) 0.180
