Table 1 Summary of semi-field evaluations of eave ribbons. The table shows details of the experiments and also whether the eave ribbons were treated or untreated, as well as the concentration of transfluthrin used. The set ups were as shown in Fig. 3

From: Eave ribbons treated with the spatial repellent, transfluthrin, can effectively protect against indoor-biting and outdoor-biting malaria mosquitoes

Experiment Control (no ribbons) Untreated ribbons Transfluthrin-treated eave ribbons No. nights Brief description
5% 1.5% 0.2% 0.02%
Experiment 1 Yes n/a n/a n/a n/a n/a 10 Baseline control experiment to assess outdoor-biting risk (using human landing catch) and indoor-biting risk (using CDC light traps)
Experiment 2.1 Yes Yes n/a n/a n/a n/a 15 Evaluating the physical barrier effect of the untreated eave ribbons (the ribbons here had no transfluthrin but were soaked in a mixture of detergent and water). Methods for assessing outdoor-biting and indoor-biting risk were same as in experiment 1
Experiment 2.2 Yes n/a Yes n/a n/a n/a 15 Evaluating protective efficacy of eave ribbons treated with different concentrations of transfluthrin, i.e. 5%, 1.5%, 0.2% and 0.02%. Methods for assessing outdoor-biting and indoor-biting risk were same as in experiment 1
Experiment 2.3 Yes n/a n/a Yes n/a n/a 15
Experiment 2.4 Yes n/a n/a n/a Yes n/a 15
Experiment 2.5 Yes n/a n/a n/a n/a Yes 15
