  1. 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.
