Table 2. Duration of Anopheles gambiae contact with bed nets.
Duration of physical contact with the bed net surface (60 min test) | ||||
---|---|---|---|---|
N | Mean total time (all contacts)1 (min) | Mean time/mosquito (25 mosquitoes)2 (s) | Mean time/mosquito (observed max number)3 (s) | |
Unbaited | 3 | 2.4 (−2.1–6.8)a | 5.7 (−5.1–16.4)a | 41.9 (−19.5–103.4)a |
Untreated | 10 | 33.1 (24.3–41.2)b | 79.5 (58.2–100.7)b | 334.1 (264.6–403.6)b |
Treated | 10 | 7.3 (3.9–10.7)c | 17.5 (9.3–25.7)c | 95.6 (57.9–133.2)c |
Mean duration of contact with the bed net surface for 60 minutes tests, as calculated for
1mean total of all contacts observed.
2mean contact time per mosquito assuming all 25 mosquitoes responded.
3mean contact time per mosquito based on the maximum number of individual mosquitoes observed simultaneously (mean and 95% confidence interval), values for each mean followed by the same letter are not significantly different between net types at p < 0.05).
