Table 4 Effect of CO2 flow rate on trap catches during screen house experiments

From: Sugar-fermenting yeast as an organic source of carbon dioxide to attract the malaria mosquito Anopheles gambiae

CO2 flow rate (ml/min) Total number

χ2-test N Mean %
caught (± sem)1
ind. CO2 no odour
0 22 16 P = 0.33 200 19.0 ± 3.0
25 86 64 P = 0.07 400 37.5 ± 6.1
60 100 22 P < 0.001 400 30.5 ± 8.0
100 177 42 P < 0.001 400 54.8 ± 7.6
250 126 32 P < 0.001 400 39.5 ± 4.9
500 71 47 P = 0.03 400 29.5 ± 4.6
  1. Ind. = industrial
  2. N = total number of mosquitoes released
  3. 1 Mean percentage caught expressed as the number of female mosquitoes caught in the two MM-X traps together divided by the number of mosquitoes that flew out of the release cage.
  4. Underlined number: significant higher catch (χ2-test, P < 0.05)
