Malaria Journal

Table 1 Blood-feeding and mortality in overnight platform trials with wild-caught mosquitoes and human sleepers.

	Number of replicates	Number of mosq. per night Mean (SD)	% blood fed (95% CI)	% 24 h mortality (95% CI)	Number of mosq. per night Mean (SD)	% blood fed (95% CI)	% 24 h mortality (95% CI)
Insecticide-treated canvas tent	9	143 (31)	0.4%* (0.2 – 0.9)	39.4%** (36.7 – 42.1)	7.2 (4.1)	9.2%** (4.2 – 19.1)	50.8%* (38.8 – 62.6)
Untreated canvas tent	6	145 (22)	2.0%* (1.2 – 3.1)	17.1%** (14.8 – 19.8)	18.8 (18.2)	46.0%** (37.1 – 55.2)	25.7%* (18.5 – 34.5)

Notes: 1. Mean percentage blood-fed, mortality and 95% confidence limits are back-transformed from values calculated by the blocked logistic regression model. 2. Significance levels between results on the treated tent and untreated tent for each genera are indicated with asterix: * = P = 0.001 ; **P < 0.001. 3. The mean number of mosquitoes per treatment per night does not provide information about the relative attractiveness of each test item: enclosed platforms were used, wild-caught mosquitoes were manually introduced to these and were then unable to leave the platform. These data are included for reference purposes only. These means do not differ significantly by t-test. 4. Due to low numbers of individual species all anophelines have been grouped.
