Tents pre-treated with insecticide for malaria control in refugee camps: an entomological evaluation

Malaria Journal

Table 2 Blood-feeding and mortality in overnight platform trials with insectary-reared An stephensi and calves as bait.

	Number of replicates	Number of mosq. per night Mean (SD)	% blood fed (95% CI)	% 24 h mortality (95% CI)
Insecticide-treated canvas tent	14	257 (76)	22.2%** (20.9 – 23.6)	80.9%** (79.5 – 82.1)
Untreated canvas tent	7	262 (105)	51.1%** (48.8 – 53.4)	5.2%** (4.3 – 6.3)

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 and one batch of insectary reared mosquitoes was released at the start of the evening (6.30–7 pm). These data are included for reference purposes only. These means do not differ significantly by t-test.
