Table 7 Mortality of mosquitoes collected from exit traps compared to those collected inside experimental huts

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

Treatment Mosquitoes in exit traps Mosquitoes indoors
  Dead mosquitoes/total mosquitoes Median1 IQR Dead mosquitoes/total mosquitoes Median2 IQR
Control 91/313 0.35 0.19 – 0.43 102/754 0.15 0.09 – 0.18
DDT 286/581 0.52 0.30 – 0.75 550/604 1.00 0.94 – 1.00
Transfluthrin coils 273/599 0.49 0.34 – 0.55 454/468 1.00 1.00 – 1.00
Metofluthrin coils 333/581 0.35 0.25 – 0.73 430/512 1.00 1.00 – 1.00
  1. Legend: The proportion of mortality induced by insecticides was measured in experimental huts in a semi field system for 16 nights. Mortality was compared between huts that had mosquito coils, DDT and no insecticides.
  2. Median1 – median proportion of mosquitoes in exit traps per hut per night; IQR – Interquartile range; Median2 – median proportion of mosquitoes inside each hut per night.
