Table 8 Insecticide induced blood-feeding inhibition of mosquitoes in experimental huts

From: An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission

Treatment Proportion of unfed mosquitoesa OR [95% CI] Mean proportion [95% CI] z value p value
Control 321/1120 1.00 [0.00 – 2.00] 0.15 [0.10 - 0.22] -7.49 NA
DDT 881/1047 13.21 [9.96 – 29.04] 0.77 [0.73 - 0.81] 24.10 <0.001
Transfluthrin coils 1164/1184 144.87 [67.19 – 382.05] 0.98 [0.96 - 0.99] 22.03 <0.001
Metofluthrin coils 1085/1146 44.27 [37.03 – 110.97] 0.93 [0.90 – 0.95] 25.57 <0.001
  1. 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.
  2. 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.
