- Legend: The proportion of mosquitos that were inhibited from blood feeding on humans was measured inside experimental huts in a semi field system for 16 nights. The proportion of unfed mosquitoes was compared between mosquito coils, DDT and no insecticide.
- aunfed mosquitoes/total number of mosquitoes recaptured from the hut; OR – Odds ratios of the proportion of mosquitoes that are likely not to feed; CI – Confidence intervals.
